    Description: Data from this century on the distribution of Caltha palustris and Hottonia palustris are used tot illustrate the role of volunteers in a monitoring scheme. Actual patterns in the distribution of the two species are discussed. About 40 percent of these data has been sampled by volunteers. It is demonstrated that both Caltha and Hottonia showed a decline in the period 1975—1989. In contrast to Caltha, the occurrence of Hottonia is strongly linked to areas with seapage water.

    Biochemical systematics of the leaf mining moth family Nepticulidae (Lepidoptera). III. Allozyme variation patterns in the Ectoedemia subbimaculella group (1990)
    In:  Bijdragen tot de dierkunde vol. 60 no. 3/4, pp. 189-197
    Details
    Publication Date: 2024-02-22
    Description: Gel electrophoretic techniques were used to analyse patterns of variation at 12 genetic loci within and among species of the Ectoedemia subbimaculella group from western Europe. Geographically separated conspecific populations were similar to one another genetically, with the exception of E. subbimaculella where the malate dehydrogenase locus exhibited clinal variation. Genetic differences among species often concerned loci that were monomorphic or slightly polymorphic within populations. Three of the species could not be diagnosed by their allozyme content; allele distribution patterns at some loci suggest that speciation took place recently and did not involve a genetic bottleneck. Phylogenetic trees constructed from allozyme data paralleled closely the phylogeny based on morphology.

    Botanical Files on Lettuce (Lactuca sativa). On the chance for gene flow between wild and cultivated Lettuce (Lactuca sativa L. including L. serriola L., Compositae) and the generalized implications for risk-assessments on genetically modified plants (1994)
    In:  Gorteria. Supplement vol. 2 no. 1, pp. 1-44
    Details
    Publication Date: 2024-02-08
    Description: In Botanical Files, a study of the real chances for gene flow from cultivated plants to the wild a system of dispersal codes (Dpdf) was introduced (see text box Dpdf).\xc2\xb37 They are indications of already occurring gene flow from cultivated plants to the wild flora, as can be deduced from herbarium collections and florisdc archives. These codes apply to the Netherlands only.\nOne of the crops of which the real chances for gene flow could not be determined, because of uncertainties regarding the relationship between the cultivated plant and its wild relatives, is Lettuce (Lactuca sativa L.). Its relationship with the wild L. serriola L. is accepted to be very close, but the species are considered to be distinguishable. In a field trial, using 350 specimens from 67 genetically different populations, the distinction between the two species proved to depend largely on character states usually connected to domestication, like absence or presence of prickles, retention of achenes, leaf texture and colour.\nThe consequences are that both wild and cultivated lettuce must be considered to belong to the same species. The finding of some \xe2\x80\x98domesticated\xe2\x80\x99 character states in \xe2\x80\x98wild\xe2\x80\x99 lettuces indicates an already ongoing gene flow between cultivated lettuce and the wild flora, and the Dp(jf-code is adapted accordingly, indicating a substantial chance for gene flow from cultivated lettuce to its wild relative in the Netherlands.\nIf the scope of Dispersal codes as in Botanical Files is extended to Europe, European Dpdf-codes are needed. In this report a model is proposed using a plant geographical division of Europe into six vegetational regions. For each species six Dpdf-codes, summarizing the chances for gene flow to each of the regions, should be developed. For the major part of the species this can be done using the information already present in national herbarium collections.

    Botanical Files. A study of the real chances for spontaneous gene flow from cultivated plants to the wild flora of the Netherlands (1992)
    In:  Gorteria. Supplement vol. 1 no. 1, pp. 1-100
    Details
    Publication Date: 2024-02-08
    Description: Separate \xe2\x80\x98Botanical files\xe2\x80\x99 have been made for 42 species of cultivated plants. Each file gives information about the cultivated plant itself (use, origin, etc.), its wild relatives in the Netherlands, a report on actual hybridization and/or crossing (indicating gene flow by pollen), and observations on escapes from the field to nature (indicating gene flow by diaspores); the information is summarized to a conclusion and a numerical code, indicating the possible ecological effects of the cultivated plant on the wild flora of the Netherlands. This study was especially undertaken for questions regarding biosafety research on Genetically Modified Organisms (GMO\xe2\x80\x99s). The sources are the herbarium collections of the State Herbarium at Leiden, floristic archives and botanical literature, as well as expert judgment on the flora of the Netherlands and crop plants. An important consideration is that the absence of certain hybrids in the State Herbarium can be interpreted as a decisive indication that such a hybrid does not occur in the wild in the Netherlands. The botanical files show that in c. 50% of the cases no gene flow is expected; in c. 15% of the cases small, often local-scale effects are expected; in c. 25% of the cases considerable gene flow to the wild is expected; in c. 10% of the cases further research should be done before a definite conclusion can be drawn (most of the cases need further taxonomic research).

    Description: Een nieuwe combinatie in Glyceria \xe2\x80\x94 Zoals door M. Kergu\xc3\xa9len in Buil. Soc. Bot. Fr. 125 (1978): 113\xe2\x80\x94120 is uiteengezet, moet de plant die tot dusver als Glyceria plicata Fries bekend stond, de (oudere) naam Glyceria notata Chevallier krijgen. Beschouwt men Glyceria declinata en G. notata als ondersoorten van \xc3\xa9\xc3\xa9n soort (de argumenten hiervoor zullen over enige tijd in Gorteria worden gepubliceerd), dan dient ook G. declinata een nieuwe naam te krijgen. Zij heet dan Glyceria notata Chevallier subsp. declinata (Br\xc3\xa9bisson) Weeda, comb. nov. (basionym: Glyceria declinata Br\xc3\xa9bisson, Fl. Normandie, ed. 3, 1859: 354).

    Description: De internationale natuurbeschermingsorganisatie I.U.C.N. begon in de jaren zeventig met de publicatie van soortenlijsten van in hun voortbestaan bedreigde organismen, de zogenaamde \xe2\x80\x98Red Data Books\xe2\x80\x99. Voor planten dateert de meest recente lijst voor Europa uit 1983.\xc2\xb9 Naast lijsten voor in Europa bedreigde soorten werden in Belgi\xc3\xab\xc2\xb2, Groot-Brittanni\xc3\xab\xc2\xb3 en Duitsland 4 ook nationale Rode Lijsten samengesteld. De huidige publicatie is bedoeld als een voorlopige eerste Rode Lijst van in Nederland bedreigde (vaat-)planten.\nNationale Rode Lijsten ontlenen hun waarde voor toepassingen op het terrein van natuurbeheer, -beleid en -bescherming uitsluitend aan de mate van betrouwbaarheid van de achterliggende gegevens. Hun betekenis is des te groter, naarmate onder deskundigen een grotere eensgezindheid over de inhoud van de Rode Lijst bestaat. De publicatie van de thans gepresenteerde Rode Lijst heeft dan ook vooral tot doel om allen die deskundig zijn op het gebied van de Nederlandse flora in de gelegenheid te stellen de Lijst op zijn merites te beoordelen. Het is de wens van de samenstellers dat deze Lijst in discussie komt, zodat eind 1990 of begin 1991 tot het maken van een tweede versie van de Rode Lijst kan worden overgegaan.

    Description: Najas minor was found again after 85 years of absence. Four species have for the first time crossed the border of the Netherlands, while extending their range: Bidens radiata, Bupleurum falcatum, Callitriche brutia, and Scirpus holoschoenus. Possible recent immigrants are Hypericum androsaemum, Leucanthemum paludosum and Polycarpon tetraphyllum. It is unlikely that Cerastium brachypetalum and Helichrysum arenahum are again part of the Dutch flora.

Ook druktechnisch is het boek van hoge kwaliteit, en met name de talrijke kleurenfoto\xe2\x80\x99s zijn een lust voor het oog.\nW. Adler, K. Oswald & R. Fischer, Exkursionsflora von Osterreich, Stuttgart, 1994, 1180 pag., 510 illustraties, DM 78, ISBN 3-8001-3461-6, Verlag Eugen Ulmer, Stuttgart, Duitsland. \xe2\x80\x94 Handzame flora van klein formaat, stevig gebonden. Voor de eerste hoofdsleutel vindt men 184 pagina\xe2\x80\x99s met hoofdstukken over taxonomie, nomenclatuur, morfologie, ecologie, endemisme, vegetatiekunde, enzovoort. De talrijke en niet altijd logische afkortingen in de sleutels en beschrijvingen bemoeilijken het gebruik: de gemiddelde Nederlander zal vaak de lange lijst van afkortingen moeten raadplegen. Over het algemeen is men terughoudend in het opnemen van \xe2\x80\x98kleine soorten\xe2\x80\x99, zoals die beschreven zijn in genera als Rubus en Taraxacum. Binnen de Orchidee\xc3\xabngenera Epipactis en Nigritella worden echter wel een aantal taxa met een zeer onduidelijke status opgenomen. De plaatjes ter verduidelijking van de sleutels zijn zeer schematisch en gering in aantal, maar waarschijnlijk had een ruimere toepassing van plaatjes het boek dikker gemaakt en dus minder bruikbaar in het veld. Het boek is zeer aan te bevelen voor de vakantieganger die meer informatie over de Oostenrijkse flora wil hebben dan de vele gidsen met kleurplaatjes kunnen bieden!

    Description: The number of new records of rare fern species (among which three new Asplenium species) is remarkable, partly due to careful inventory work, but also because of spontaneous area expansion. Also Acer negundo and Stachys recta may show this phenomenon. It is uncertain whether Silene gallica must still be considered as extinct. Fortunately Wahlenbergia hederacea is part of the living flora again.

    Publication Date: 2024-01-12
    Description: A new species of the tropical-subtropical genus Monanchora Carter, 1883, is reported from S\xc3\xa3o Tiago (Cape Verde Islands) and Ascension Island. The new species, M. stocki n. sp., is compared with related Atlantic and Indo-Pacific species, viz. Caribbean M. arbuscula (Duchassaing & Michelotti, 1864) (senior synonym of Echinostylinos unguiferus De Laubenfels, 1953, and Monanchora barbadensis Hechtel, 1969), and Indo-Pacific M. unguiculata (Dendy, 1922). The new species stands out among Monanchora species by the longer and more pointed teeth of its spatulate-unguiferate chelae, which in extreme cases almost meet. The structure of the chelae of Monanchora species of various parts of its range are compared with that found in some other (? related) genera, leading to critical remarks on current familial classifications of the Poecilosclerida.

    Description: According to electrophoresis and erythrocyte size the genotypes of 756 waterfrogs, collected during 1986\xe2\x80\x941988 in 54 localities in The Netherlands, were classified as belonging to 5 different genotypes: 331 diploid R. lessonae (LL), 5 triploid R. lessonae (LLL), 250 diploid R. kl. esculenta (LR), 133 triploid R. kl. esculenta (LLR), and 37 diploid R. ridibunda (RR).\nThe occurrence of triploid R. kl. esculenta in The Netherlands is reported for the first time and triploid R. lessonae has not yet been reported previously. There are indications that LL gametes could be produced by LLR triploids and LL diploids. R. kl. esculenta in R. kl. esculenta and R. ridibunda \xe2\x80\x94 R. kl. esculenta populations of the western regions seems to be exclusively triploid, whereas the percentage of triploid R. kl. esculenta in R. lessonae \xe2\x80\x94 R. kl. esculenta populations of the eastern regions is about 1%.\nBiometrical differences were neither found between R. kl. esculenta triploid and diploid, nor between R. lessonae triploid and diploid.

    Description: The genus Guineapsaltria is erected for eight species, distributed in New Guinea and northeastern Queensland. Five species are transferred from the genus Baeturia St\xc3\xa5l, 1866 and redescribed, viz. G. chinai (Bl\xc3\xb6te, 1960), G. flava (Goding & Froggatt, 1904), G. pallida (Bl\xc3\xb6te, 1960), G. stylata (Bl\xc3\xb6te, 1960), and G. viridula (Bl\xc3\xb6te, 1960), while three species are described as new to science (G. flaveola n. sp., G. pallidula n. sp., and G. pennyi n.sp.). G. flava is designated as the type species of the genus. Baeturia minuta Bl\xc3\xb6te, 1960 is synonymized with Guineapsaltria flava. The phylogeny of Guineapsaltria is discussed and some remarks are made on its phylogenetic relationships with other New Guinean and Australian tibicinid genera. A key to the males and maps of distribution are presented.

    Description: Lovenula (Neolovenula) alluaudi is widespread on Lanzarote, where it occurred at 22 of the 105 stations. On Fuerteventura it was found at only 2 of the 53 stations, both in the extreme northwest part of the island. It was also found in a reservoir on the south side of the small island of Alegranza. Samples collected at several hundred stations in the other Canary Islands failed to yield a single calanoid, supporting the belief that the eastern islands are fragments of the African continent that drifted to deeper waters.\nMales outnumbered females in about 2/3 of the samples, often heavily.

    Description: Burrington Baker (1924) states that Cura\xc3\xa7ao can be divided into three distinct faunal areas. Stock (1977) mentions the occurrence of three subspecies of hadziid amphipods almost exclusively confined to different parts of Cura\xc3\xa7ao. The results of a study of the distribution on this island of various subspecies of the gastropods Cerion uva, Brachypodella raveni, Tudora megacheilos and T. rupis, however, do not support the hypothesis of a tripartite Cura\xc3\xa7ao.

    Publication Date: 2024-01-12
    Description: Mantra speciosa Leigh-Sharpe, 1934 (ex Poecilostomatoida), collected during the Siboga Expedition is redescribed on the basis of the holotype female. The 15-segmented antennule and the gnathostomous nature of the mouthparts exclude the Mantridae from the Poecilostomatoida and point to a relationship with the tunicate-infesting families Ascidicolidae, Notodelphyidae and Archinotodelphyidae (Cyclopoida). Nearchinotodelphys indicus Ummerkutty, 1960 (ex Archinotodelphyidae) is transferred to the Mantridae. It is suggested that the bivalveinhabiting mantrids have diverged from the ascidicolous lineage leading to the Notodelphyidae and Ascidicolidae.

    Details
    Publication Date: 2024-01-12
    Description: In many copepod species adult males clasp females for an extended period before transferring spermatophores. Clasping juvenile females (first to fifth copepodid inclusive) is interpreted as mate guarding and is shown to be widespread among podoplean copepods. It is distinct from copulation, which takes place only between adults and is often distinguishable from mate guarding by a difference in clasping posture.

    Genetic differentiation and estimated levels of gene flow in members of the Gammarus pulex-group (Crustacea, Amphipoda) in western Europe (1990)
    In:  Bijdragen tot de dierkunde vol. 60 no. 1, pp. 3-29
    Details
    Publication Date: 2024-01-12
    Description: Genetic differentiation of morphologically variable members of the G. pulex-group in northwestern Europe was investigated by electrophoresis at 20 enzyme loci. Five recently described related forms were examined with reference to the \xe2\x80\x9cclassical\xe2\x80\x9d species G. pulex, G. wautieri and G. fossarum. G. pulex and G. wautieri were shown to be genetically homogeneous and clearly distinct species. In the other species, morphologically similar forms were shown to be genetically distant, and inter-areal intraspecific genetic differentiation may warrant recognition of subspecies or sibling species. In some cases, levels of reproductive isolation of the forms involved could be assessed by cross-breeding experiments. To estimate dispersal capabilities, gene flow levels were indirectly estimated from gene frequency data. Gene flow levels are generally low and fluctuating population sizes may enhance the occurrence of stochastic processes. Dendrograms derived from genetic distances were compared with zoogeographical and paleoclimatological evidence. The distribution areas of the species involved correspond to patterns predicted by these data.

    Description: The family Archimonocelididae Meixner, 1938 has been revised. The family contains two subfamilies, each comprising two genera: the Archimonocelidinae with Archimonocelis Meixner, 1938 and Meidiama Marcus, 1946, and the Calviriinae subfam. nov. with Asilomaria Karling, 1966 and Calviria gen. nov. with 20, 2, 1, and 3 species, respectively, 13 of which are new to science. The type species of the family is redescribed. Material of all the Archimonocelididae genera has been studied and supplementary remarks are made on some known species. The karyotype of 14 species is described. Archimonocelis has a cosmopolitan distribution while Meidiama is restricted to the South American coast, Calviria to the Mediterranean, and Asilomaria to the Pacific North American coast. The phylogenetic relationships within the family are analysed.

    Description: The viridis group is proposed for a supposedly monophyletic group of seven New Guinean species of the cicada genus Baeturia St\xc3\xa5l, 1866. Three species (B. brongersmai Bl\xc3\xb6te, B. rufula Bl\xc3\xb6te, and B. viridis Bl\xc3\xb6te) are redescribed and four species (B. furcillata, B. karkarensis, B. lorentzi, and B. turgida) are described as new to science. A key to the males is provided. The phylogenetic position of the viridis group within the genus Baeturia is discussed. The distribution of shared characters suggests a subdivision of the group into two subgroups. One subgroup is restricted to southern and western Irian Jaya, while the other is distributed along the coastal mountain ranges of northern New Guinea, including Karkar Island.

    The taxonomic significance of the short-shafted mesotriaene reviewed by parsimony analysis: validation of Pachastrella ovisternata Von Lendenfeld (Demospongiae: Astrophorida) (1993)
    In:  Bijdragen tot de dierkunde vol. 63 no. 3, pp. 129-148
    Details
    Publication Date: 2024-01-12
    Description: The spicule complement of a demosponge specimen collected from the Atlantic coast of Spain was noted to be similar to that of Pachastrella monilifera, but particularly characterized by the presence of short-shafted mesotriaenes. After detailed examination, it was concluded that the specimen undoubtedly belonged to the species Pachastrella ovisternata Von Lendenfeld, 1894. For a long time, this species has been regarded a synonym of Pachastrella monilifera Schmidt, 1868. Examination of this new specimen showed that Pachastrella ovisternata was a valid species of the genus Pachastrella. Moreover, it denoted the real existence of mesotriaenes in this genus.\nThe parsimony analyses indicated that the species Yodomia perfecta, traditionally assigned to the genus Yodomia by the presence of mesotriaenes, ought to be reclassified in the genus Pachastrella, close to P. ovisternata. These analyses also showed that mesotriaenes are a product of a convergent evolution in shape of tetraxon spicules in Calthropellidae and Pachastrellidae. At the species level it is suggested that short-shafted mesotriaenes have arisen more than once in the family Pachastrellidae. Thus, the presence of mesotriaenes itself cannot be regarded as a diagnostic characteristic at generic level. However, it was noted to be a reliable feature in order to distinguish taxa at specific level.

    Publication Date: 2024-01-12
    Description: The Niphargus transitivus group includes 12 groundwaterdwelling species. It is defined by an upright body position during locomotion, a small, stout body with short appendages, except for long coxae and dactyli, coxae V-VI equilobate or posterolobate, accessory flagellum subject to reduction, and the body endowed with adaptations for volvation ( = ability to enroll into a ball).\nThe biogeography of this southeastern European group of species is discussed and a cladistic analysis of the group is presented. Some cases of parallel character evolution in groundwater amphipods are mentioned. The inference of biogeographic and phylogenetic information in elucidating the evolutionary history of the group is hampered by inconsistency of the data. One of the hypotheses about the evolutionary history of the group is thought to be the most parsimonious.

    Details
    Publication Date: 2024-01-12
    Description: The critical function is an important aspect of the science of taxonomy. Every classification is built upon a critical evaluation and emendation of a previously existing one. Ultimately, this reaches back to pre-scientific classifications which are, like scientific ones, hierarchically structured. The critical function is strongly developed in phylogenetic systematics in which some time-honoured taxa are no longer considered natural groups. Rejection of paraphyletic taxa has given rise to opposition against the phylogenetic methodology. It is suggested that paraphyletic taxa may be retained for administrative reference, but not for scientific evaluation of biogeography and evolutionary differentiation.

    Description: Recently the scientific correspondence of the Dutch zoologist P.P.C. Hoek (1851\xe2\x80\x941914) turned up in the Artis Library. This collection contains three hitherto unpublished letters from Charles Darwin. It appears that Charles Darwin recommended Hoek to the favour of Sir Charles Wyville Thomson upon Hoek\xe2\x80\x99s request for duplicates of Pycnogonida collected by the Challenger Expedition. This led to Hoek\xe2\x80\x99s participation in the publication of the scientific results of the Challenger Expedition. Hoek\xe2\x80\x99s report on the Pycnogonida was published in 1881 and those on the Cirripedia in 1883 (Systematic Part) and 1884 (Anatomical Part). In a letter to Hoek dated November 23, 1881 Charles Darwin praises Hoek\xe2\x80\x99s contribution on the Pycnogonida as a magnificent piece of work with admirable plates.

    Description: A new family Cristacoxidae is proposed to accommodate the monotypic genera Cristacoxa gen. nov., Noodtorthopsyllus Lang (ex Canthocamptidae) and Cubanocleta Petkovski (ex Laophontidae). Cristacoxa petkovskii gen. et spec. nov. is described on the basis of a single male collected from coralline sand of Bonaire, West Indies. N. psammophilus Noodt and C. noodti Petkovski are redescribed and refigured on the basis of new material from the Gal\xc3\xa1pagos (Isla Santa Cruz), the West Indian Islands (Cura\xc3\xa7ao, Klein Cura\xc3\xa7ao, Bonaire) and the Canary Islands (El Hierro, Tenerife). The new family is characterised by the presence of an outer spinous process on the first antennular segment, the absence of the antennary exopod, the uniramous mandibular palp, the presence of conspicuous cristae on the precoxa and coxa of leg 1 and the elongation of the apical exopodal spines of P2 to P4. The Cristacoxidae are unique in having an equal number of setae/spines on the P5 in both sexes. Examination of the ontogeny of this leg in males and females of Orthopsyllus spec. gives strong evidence that the cristacoxid P5 has undergone neotenous evolution. Males of Cristacoxidae are readily recognisable by their extremely long spermatophores. The new family is allocated to the superfamily Laophontoidea T. Scott, together with the Laophontidae T. Scott, the Laophontopsidae Huys & Willems, the Orthopsyllidae Huys and the Adenopleurellidae Huys. A phylogenetic analysis of the relationships within the superfamily is presented, and as a result Por\xe2\x80\x99s (1986) concept of the Laophontoidea is refuted. Instead, it is concluded that the superfamily can be defined on the basis of the following apomorphies: (1) antennules with outer spinous process on segment 2; (2) antenna with allobasis bearing 1 seta; (3) antennary exopod quadrisetose; (4) P1 exopod without inner seta on exp-2 and 4 setae/spines on exp-3; (5) P1 endopod 2-segmented with elongated enp-1 and 2 elements on enp-2; (6) P2\xe2\x80\x94P4 with 2-segmented endopods; exp-1 without inner seta; (7) sexual dimorphism of P3 endopod; (8) P6 bisetose with one member fused to somite. There is no close relationship neither with the Normanellidae Lang, nor with the Ancorabolidae T. Scott. The Laophontidae are considered the first offshoot in the evolution of the Laophontoidea because of the retention of the 8-segmented antennule in both sexes and the ancestral seta formulae on P2\xe2\x80\x94P4. The other families can be assigned to two clades: the Adenopleurellidae and the Laophontopsidae-Cristacoxidae-Orthopsyllidae-grouping. The Laophontopsidae and the Cristacoxidae are sister groups because of the shared sexual dimorphism of the P3 endopod (advanced type), and the fusion of antennular segments distal to the geniculation in the male. Emphasis is placed on the postembryonic development in the Laophontoidea of the male P3 endopod and P6 and on their homologies in the female. A reconstruction of the hypothetical ancestor of the Laophontoidea is presented.

    Description: The pseudoscorpions of the genera Chthonius C.L. Koch, 1843 (Chthoniidae) and Roncus L. Koch, 1873 (Neobisiidae) from caves in Serbia, Yugoslavia, have been studied. Three new species, Chthonius (Globochthonius) purgo, Chthonius (Ephippiochthonius) kemza, and Roncus talason are described. A reanalysis of the type material of three subspecies of Chthonius and Roncus from Serbian caves has supported their elevation to full specific rank: Chthonius (Globochthonius) pancici \xc4\x86ur\xc4\x8di\xc4\x87, 1972, Roncus remesianensis \xc4\x86ur\xc4\x8di\xc4\x87, 1981, and R. timacensis \xc4\x86ur\xc4\x8di\xc4\x87, 1981. All species studied are considered endemics of the Balkan Peninsula. Diagnostic characters of the analysed taxa are thoroughly described or figured. Taxonomic interrelationships and geographical distribution are briefly discussed.

    Neocyclops Gurney from Brazilian sandy beaches (Copepoda: Cyclopoida) (1993)
    In:  Bijdragen tot de dierkunde vol. 63 no. 3, pp. 163-172
    Details
    Publication Date: 2024-01-12
    Description: Neocyclops medius Herbst, 1955 and Neocyclops vicinus (Herbst, 1955) are redescribed from intertidal interstitial water of sandy beaches along the Brazilian coast. The male of N. vicinus is described for the first time.\nNeocyclops vicinus can be easily distinguished from N. medius by the relatively longer caudal rami, the presence of a mandibular palp, and the sexually dimorphic antenna.\nThis study revealed the leg 4 endopodite segments 2 and 3 as being fused in both species. The terminal segment of the 2-segmented leg 4 endopodite of the copepodite 5 does not differentiate into 2 distinct segments during the molt to adult. The plane of fusion is marked by a thin and incomplete line on the frontal surface. This scar was erroneously interpreted as a functional articulation by Herbst (1955). Topotypes of N. salinarum (Gurney, 1927) examined showed a similar fusion of those segments of leg 4.\nPopulations from the Black Sea coast ascribed to N. vicinus differ from the Brazilian specimens in a number of morphological details, sufficient to propose that they represent a separate taxon, perhaps N. remanei (Herbst, 1952).\nA diagnosis for Neocyclops is provided.

    Morphological characterization, cytogenetic analysis, and geographical distribution of the Pygmy Marbled Newt Triturus marmoratus pygmaeus (Wolterstorff, 1905) (Caudata: Salamandridae) (1993)
    In:  Bijdragen tot de dierkunde vol. 63 no. 1, pp. 3-14
    Details
    Publication Date: 2024-01-12
    Description: Triturus marmoratus pygmaeus, a problematic subspecies of the Marbled Newt from the southern part of the Iberian Peninsula, is redescribed using specimens collected in the \xe2\x80\x9ctypical\xe2\x80\x9d area. Diagnostic external morphological features are provided to permit the accurate determination of the specimens belonging either to T. m. marmoratus or to T. m. pygmaeus. These diagnostic features were applied to individuals both from the field and from museum collections. The results indicate a larger distributional area for T. m. pygmaeus than was previously recognized. The distribution of T. m. marmoratus ranges over the northern half of the Iberian Peninsula and most of France; T. m. pygmaeus occupies the southwestern part of the Iberian Peninsula. The contact area between the two subspecies seems to be located along the Central Range Mountains (Sistema Central) in Portugal and Spain. T. m. marmoratus extends southwards beyond this borderline in three areas: Serra da Estrela (Portugal), Sierra de Gata (Spain) and Sierra de Guadarrama (Spain). The only point at which T. m. pygmaeus reaches northwards beyond the Central System is near Puerto de Malag\xc3\xb3n (Madrid Province, Spain). No cases of strict sympatry, nor individuals with intermediate morphological features have been observed. The results of an extensive cytogenetical analysis do not show any differences between T. m. pygmaeus and T. m. marmoratus. Interestingly, however, the T. m. pygmaeus populations from Do\xc3\xb1ana (Huelva Province, Spain) showed an exclusive, though little differentiated, C-banding pattern.

    New species of Zyzzya, Cornulella, Damiria, and Acheliderma (Porifera: Poecilosclerida), with a review of fistular genera of Iophonidae (1994)

    Publication Date: 2024-01-12
    Description: New sponge species belonging to the closely related fistular genera Zyzzya, Cornulella, Damiria, and Acheliderma are described from reef habitats off the coasts of Colombia, Bonaire and Cura\xc3\xa7ao in the southern Caribbean. With very few exceptions these sponges are small to tiny specimens inhabiting crevices and other cryptic habitats; some may be excavating. For comparison both published and unpublished material belonging to these genera from other parts of the world was examined, and this yielded several nomenclatorial changes and a further three new species from the Indian Ocean. The new species are: Zyzzya invemar (Caribbean), Cornulella santamartae (Caribbean), C. tyro (Seychelles), C. amirantensis (Seychelles), Damiria leonorae (Caribbean), D. toxifera (Seychelles) and Acheliderma lisannae (Caribbean). All species belonging to these genera, as well as to the closely related Indo-Pacific genus Paracornulum, are briefly diagnosed. The genera and species of this group are found to be distributed over tropical and subtropical waters of all three oceans. The five genera were so far of controversial systematic allocation, although their close relationship with Cornulum was generally accepted. The recently revived family Iophonidae is demonstrated to be the likely assemblage for them. A brief survey of Iophonidae genera is presented and a preliminary phylogenetic analysis of the fistular genera is attempted. Although several parts of the phylogenetic relationships remain unsolved, it is nevertheless clear that in all genera the closest relatives are not found in adjacent areas, but are often disjunct.

    Description: Two new clausidiid copepods of the genus Hemicyclops (Poecilostomatoida: Clausidiidae) associated with mud shrimps are described from Brazil: Hemicyclops caissarum sp. n. associated with Callichirus major (Say, 1808) from a beach in Santos and Hemicyclops sebastiani sp. n., in burrows of Callichirus guassutinga (Rodrigues, 1971) in S\xc3\xa3o Sebasti\xc3\xa3o. H. caissarum is closest to H. carinifer Humes, 1965 from Madagascar and H. sebastiani can be easily distinguished from all its congeners by the presence of a thick, densely plumose seta on the antennule segment 2, and the greatly enlarged tergal plate of the 4th pediger. New records of Hemicyclops subadhaerens Gooding, 1960 and Hemicyclops thalassius Vervoort & Ramirez, 1966 from the Brazilian coast are also included.

    A black, non-troglomorphic amphibian from the karst of Slovenia: Proteus anguinus parkelj n. ssp. (Urodela: Proteidae) (1994)
    In:  Bijdragen tot de dierkunde vol. 64 no. 1, pp. 33-53
    Details
    Publication Date: 2024-01-12
    Description: A morphologically distinct cavernicolous salamander Proteus anguinus from southeastern Slovenia (Bela Krajina) is described as P. a. parkelj ssp. n. It differs from P. a. anguinus in a dark pigmentation, fully developed eyes, a skull with broader and shorter bones and fewer teeth, a voluminous jaw musculature that gives the head a bulky appearance, a proportionally longer trunk with a higher number of vertebrae, shorter extremities, and a shorter tail. Most of these traits are considered to be plesiomorphic character states. An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Sti\xc4\x8dna (DNei = 0.23). Both populations in turn are genetically dissimilar to a geographically more distant population from Postojna (DNei = 0.49). The observed level of genetic differentiation suggests that western and southeastern Slovenian populations form separate lineages since the uppermost Miocene but conservatively hitherto only a single species is recognised. The new taxon is only known from a small area and may be rare. P. a. parkelj now under strict legal protection, is threatened by industrial pollution.

    Paul Louis Steenhuizen (1870-1940) : preparateur en vogelfotograaf (1990)
    Details
    Publication Date: 2024-01-12
    Description: Om een tentoonstelling aan de preparateur P .L. Steenhuizen te kunnen wijden, \nmoest voor het Zo\xc3\xb6logisch Museum te Amsterdam eerst meer informatie over \nSteenhuizen verzameld worden. Tijdens het bijeenzoeken van informatie bleek \nniet over alle aspecten van het leven en werk van Steenhuizen evenveel bekend \nte zijn. Dit heeft tot gevolg, dat in de navolgende biografie niet op alle aspecten \neven gedetailleerd ingegaan kan worden. Uit het materiaal is gebleken, dat de \nkeuze van het museum om een tentoonstelling aan Steenhuizen te wijden een \nzeer goede is, want Steenhuizen heeft duidelijk zijn sporen achtergelaten in de \ngeschiedenis van Artis en het Zo\xc3\xb6logisch Museum. \nIn de tijd, dat Steenhuizen bij Artis werd aangesteld, was in vele natuurhistorische musea de taxonomische opstelling ten dienste van de wetenschapper nog gebruikelijk. Heimans & Thijsse trachtten echter de natuurbeleving en \nde veldbiologie populairder te maken bij het grote publiek. Wat zij veelal met \nboeken en artikelen in kranten en tijdschriften deden, poogde Steenhuizen te \nbewerkstelligen met zijn eigen werk: vogelgroepen, diorama\'s en vogelfoto\'s. \nSteenhuizen had ook de unieke gelegenheid zijn hobby (vogels) ten dienst te \nmaken aan zijn museumwerk. De kennis over vogels, die hij tijdens zijn vele \ntochten opdeed, verwerkte hij in zijn prepareerwerk. De bezoekers van de \nverschillende instellingen, waar zijn werk te zien was, profiteerden daar op \nhun manier ook weer van. Hoewel natuurlijk met instemming van zijn \nsuperieuren, kreeg Steenhuizen de gelegenheid met zijn vogelgroepen een \noverheersend stempel te drukken op het zogeheten Museum Fauna \nNeerlandica. \nDe uitdrukking "wie schrijft, die blijft" is op Steenhuizen als volgt van \ntoepassing: Heimans & Thijsse hebben veel geschreven, zodat zij ook nu nog \nnaamsbekendheid genieten; Steenhuizen schreef niet, zijn prepareerwerk \ndoorstond de tand des tijds maar ten dele, zodat hij nu tot de rang der \nonbekenden behoort. Van het kaliber Heimans & Thijsse was hij niet, maar hij \nverdient meer dan anonimiteit. De tentoonstelling van het Zo\xc3\xb6logisch Museum \n is een poging om hem daarvoor te behoeden. \nHoewel volledigheid is nagestreefd, blijven aanvullingen mogelijk. \nDe samensteller staat open voor alle op- en aanmerkingen, correcties, \naanvullingen etcetera, die lezers na het lezen van de navolgende biografie \nzouden kunnen hebben. Mogelijke bijdragen worden wellicht in een herziene \n(en eventueel uitgebreide) versie verwerkt . \nWanneer in het navolgende verhaal sprake is van Artis wordt of het Koninklijk \nZo\xc3\xb6logisch Genootschap "Natura Artis Magistra" of de door dit genootschap \nbeheerde diergaarde bedoeld. Tenslotte bedankt de samensteller iedereen, die op \nwat voor manier dan ook heeft bijgedragen aan de samenstelling van de \nnavolgende biografie.

    Description: Seven species of Tubificidae are recorded from the Canary Islands, viz. Heterodrilus amplus n. sp., Coralliodrilus leviatriatus Ers\xc3\xa9us, 1979, Limnodriloides agnes Hrab\xc4\x95, 1967, L. janstocki n. sp., Aktedrilus cuneus Ers\xc3\xa9us, 1984, A. parvithecatus (Ers\xc3\xa9us, 1978), and Tubifex tubifex (M\xc3\xbcller, 1774); the two latter taxa are reported also from the Cabo Verde Islands. All taxa except T. tubifex are marine and there is no evidence of endemism in the freshwater oligochaete fauna of these islands. Heterodritus amplus has short, spindle-shaped, heavily muscular atria; they are morphologically unique within the genus. Limnodriloides janstocki has modified spermathecal setae; it is distinguished from similar species by its long atrial ducts and deep, elaborate copulatory sacs.

    Gammaridea and Caprellidea (Crustacea \xe2\x80\x94 Amphipoda) of the Portuguese south-western continental shelf: taxonomy and distributional ecology (1991)
    In:  Bijdragen tot de dierkunde vol. 61 no. 2, pp. 65-87
    Details
    Publication Date: 2024-01-12
    Description: Amphipods from the Portuguese south and south-western continental shelf were studied with regard to the species inventory, distribution, and ecology. This study allowed the identification of 113 species, belonging to 52 genera; of these species 28 are recorded for the first time along the Portuguese coast. Two species, Ampelisca heterodactyla Schellenberg, 1925, and A. latifrons Schellenberg, 1925, are redescribed. The latter is different from the Ampelisca named latifrons by Ledoyer in 1972 and 1982.\nThe absolute frequencies and abundances of the species, and their distribution in terms of bathymetry and type of substrate are also analysed. The most frequent and abundant species also presented wide ranges of vertical distribution. In addition, these species are preferentially found in medium or fine sand bottoms. The granulometric structure of the habitats might, therefore, be the most important factor conditioning the development of amphipod populations. The group of the most frequent and abundant species was dominated by Ampelisca. Thus, at least in the shelf sediments, the species of this genus might have a key role as food for many secondary consumers, especially demersal fishes.

    Description: Many of the lower metazoans reach adulthood via complex developmental stages. Each of these stages is described with a specialized terminology, which is different for every major group of organisms. Biologists with a proper training in biodiversity may have learned about these complex issues during their undergraduate days, but many of us do no longer encounter the intricacies of lower metazoan development in later stages of our careers. We may be familiar with the ontogenetic stages in the group on which we specialize, but only a few will have practical knowledge and an overview of the larval stages in such groups as crustaceans, echinoderms, polychaetes, sipunculans, molluscs, flatworms, bryozans, and nemertines. Donald Williamson certainly belongs to the last-mentioned category of biologists.\nIn this book, Williamson addresses the situation that marine invertebrates from highly distinct and not closely related phylogenetic lines may develop from very similar larvae. There are many examples of distinct lower metazoan lineages sharing highly similar early developmental stages.

    Frustrating facts about area cladistics and species individuality (1990)
    In:  Bijdragen tot de dierkunde vol. 60 no. 3/4, pp. 151-154
    Details
    Publication Date: 2024-01-12
    Description: Area cladistics suffer from the fact that areas have various \xe2\x80\x9chistories\xe2\x80\x9d, as such dictated by different groups of taxa. Consequently, a generalized area cladogram has not or hardly any biological meaning. Conflicting area cladograms may be derived from even the same species, when their ranges in different geological periods are used. This is a consequence of the individuality of species.

    Description: Samples collected in underground waters of Spain by Ine Meijers and Jos Notenboom demonstrated the presence of some oculated asellids previously known: Proasellus coiffaiti, P. coxalis, and P. meridianus, and also four new stygophilous species, more or less depigmented, with different stages of regression of the ocular system: P. beticus n. sp., P. ortizi n. sp., P. aragonensis n. sp., and P. ebrensis n. sp. These forms represent relict populations of ancient epigean species. The anophthalmous species of the Aquitanian Basin, Pyrenees, and Iberian Peninsula are more closely related to P. beticus and P. ortizi than to the Recent epigean species P. coxalis and P. meridianus.

    Publication Date: 2024-01-12
    Description: It is shown that the pinnacle of Max Weber\xe2\x80\x99s scientific career was the organization and leadership of the Siboga Expedition to the former Netherlands East Indies (now Indonesia) in the years 1899\xe2\x80\x941900. Before that time, as Professor of both General and Special Zoology at the University of Amsterdam, he had devoted his research mainly to the anatomy of mammals, which resulted in the fundamental reference work Die S\xc3\xa4ugetiere published in first edition in 1904.\nJust before his departure with the Siboga Expedition Weber was appointed Extraordinary Professor of Special Zoology in Amsterdam. This gave him more time to edit the results of the Siboga Expedition and for taxonomic studies, especially on the fishes of the Indo-Australian Archipelago. Nevertheless he kept a keen interest in general zoology, which resulted in his extensive contribution to the modern textbook Lehrbuch der Biologie f\xc3\xbcr Hochschulen co-authored by Moritz Nussbaum and Georg Karsten, published in first edition in 1911.\nWeber retired in 1921 and by the time he died in 1937 about 95% of the scientific results of the Siboga Expedition had been published \xe2\x80\x93 an outstanding achievement.

    Details
    Publication Date: 2024-01-12
    Description: A new analysis within the framework of developmental genetics provides both raw data and theoretical support to the \xe2\x80\x9cold\xe2\x80\x9d morphology and suggests a new, more predictive, approach to the concept of homology. We distinguish between \xe2\x80\x9cpositional homologues\xe2\x80\x9d and \xe2\x80\x9cstructural homologues\xe2\x80\x9d as independent components of the more general concept of homology. We discuss some general patterns seen in the anatomy of animals and in their morphogenesis. Slack et al. (1993) advanced the concepts of the \xe2\x80\x9czootype\xe2\x80\x9d, a particular spatial pattern of gene expression, and the \xe2\x80\x9cphylotype\xe2\x80\x9d, a particular stage of embryonic development that expresses the zootype. We build upon these concepts and expand them. This allows us to propose some additional phylotypes (arthrotype, cyclotype, platytype, malacotype, trimerotype) that may guide future investigations towards understanding the genesis of metazoan form.

    Growing knowledge and understanding of dichromatism and sex reversal in Labridae (1990)

    Details
    Publication Date: 2024-01-12
    Description: A brief survey is given of current literature in comparison with former studies. Since the 18th century phenotypic diversity of Labridae is a matter of argument. At first in dribs and drabs, yet last decades at a rapid rate, dichromatic adult morphs are synonymized. There are few monochromatic species.\nWrasses are protogynous hermaphrodites. Most species are described as monandric, but a minority (of slightly or extremely dichromatic) species is diandric, with both primary and secondary males. Terminal males reproduce with single females, but initial phase males spawn in aggregations. Some species are haremic, and large males are permanently or temporarily territorial. Last decades insight in the various social factors has greatly increased, resulting in theoretic models to explain the evolution of the typical, diverse modes of labrid reproductive biology.

    Details
    Publication Date: 2024-01-12
    Description: The new genus and species, Dicrotrichura tricincta, is described from deep mud (1220 m) in the Ligurian Sea (western Mediterranean). It is the first tantulocaridan not found to be attached to a crustacean host but free living in the sediment. It is assigned to the Deoterthridae on the basis of the absence of a rostrum, the abdominal segmentation and the characteristic cephalic pore pattern. It can be distinguished from all known tantulocaridans in the presence of peculiar, bi-articulated caudal setae and the difference in thoracopodal setation between leg 2 and legs 3-5. Some new structures located on the attachment disc are described for the first time. D. tricincta is the second tantulocaridan to be recorded from the Mediterranean.

    Seasonal variation in copepod abundance in relation to other zooplanktonic groups in the northwestern Mediterranean (1993)
    In:  Bijdragen tot de dierkunde vol. 62 no. 4, pp. 215-226
    Details
    Publication Date: 2024-01-12
    Description: Abundance of adult copepods and late copepodid stages from the upper 50 m in the Golfe du Lion (N.W. Mediterranean) was studied by the author in 1986, 1987, and 1988 for each season. Altogether 87 stations at 22 fixed locations were sampled in the frame of the multidisciplinary French/Spanish programme P\xc3\xa9lagolion/Leopel in the near-coastal region (\xe2\x89\xa4 25 m bottom depth), the Rhone dilution zone, the neritic region (\xe2\x89\xa4 200 m bottom depth), and the oceanic region (200\xe2\x80\x942000 m bottom depth). Abundance of other zooplanktonic groups was estimated and total zooplankton biomass was determined for the upper 50 m. Copepod abundance was highest during September 1986 (all regions) and July 1987 (neritic). Total biomass was highest during July 1987 and May/June 1988, caused by high abundance of many other zooplankters.\nMost abundant copepod species were: Clausocalanus spp., Paracalanus parvus (Claus, 1863), Oithona spp., Oncaea Corycaeus spp., spp., Centropages typicus Kr\xc3\xb8yer, 1849, Calanus helgolandicus (Claus, 1863), and Temora stylifera (Dana, 1849). Generally, copepodids slightly outnumbered the adult copepods in the coastal and neritic region, but they were twice to three times more numerous than adults in the oceanic region. Beside copepods, Cladocera formed the most important group at the near-coastal stations near the Rhone mouth; Siphonophora and Salpidae were most abundant at the neritic and oceanic stations.

    Details
    Publication Date: 2024-01-12
    Description: The taxonomie concept of the subfamily Normanellinae Lang (Harpacticoida, Laophontidae) is revised. As a result a new family Laophontopsidae is proposed to accommodate Laophontopsis Sars and two new genera Aculeopsis and Telodocus. It is concluded that the presumed boreo-mediterranean distribution pattern displayed by the type species L. lamellifera (Claus) is merely the result of erroneous identifications. The population of northwest Europe is assigned to a new species L. borealis and another new species L. monardi is proposed for Monard\xe2\x80\x99s (1928) material from Banyuls-sur-Mer. L. secundus Sewell is placed in the new genus Telodocus. Aculeopsis gen. nov. embraces only A. longisetosa spec. nov. and constitutes the most primitive genus of the family. The Laophontopsidae are placed within the superfamily Laophontoidea. The Normanellinae are provisionally upgraded to family level despite their diphyletic status because this narrows the diagnosis of the Laophontidae considerably. The genera are attributed to two clearly defined but non-related subfamilies, Normanellinae Lang (Normanella Brady) and Cletopsyllinae subfam. nov. (Cletopsyllus Willey, Pseudocletopsyllus Vervoort). The genus Pseudocleta Lang is relegated to incertae sedis within the Laophontoidae.

    Description: From June till December 1987 an inventory of the excavating sponges of the Santa Marta area, Colombian Caribbean, was made by scuba diving to depths not exceeding 18 m. Sixteen species were recorded and compared morphologically, using spicule sizes, papillae shapes, and excavation characteristics. Four littleknown species are fully described and illustrated by submarine color photographs in situ. One appears to be a new species: Axinyssa flavolivescens, belonging to a genus not known to excavate so far. The other three species could not be identified with certainty: Aka \xc3\xa4ff. xamaycaensis, Aka aff. brevitubulata, and Cliona aff. flavifodina. A key to the excavating sponges of the area studied is provided.

    Revision of the Archiloa genus complex with description of seven new Archilina species (Platyhelminthes, Proseriata) from the Mediterranean (1994)

    Description: Based on morphological and karyological investigations, the genus complex Archiloa sensu Karling (1966) is revised. The group contains seven genera, two of which are here described as new: Archiloa de Beauchamp, 1910, Archilopsis Meixner, 1938, Mesoda Marcus, 1949, Monocelopsis Ax, 1951, Archilina Ax, 1959, Inaloa gen. n., and Tajikina gen. n. The genus Pistrix Marcus, 1951 is synonymized with Mesoda Marcus, 1949. Eleven species are transferred to other genera. Seven new Archilina species are described from the Mediterranean: A. brachycirrus, A. deceptoria, A. etrusca, A. palestinica, A. selenifera, A. biselenifera, and A. caliban. Two distinct \xe2\x80\x9cmorphs\xe2\x80\x9d are recognized within A. endostyla Ax, 1959. The genus Archilina now contains 12 species, 8 of which occur in the Mediterranean. The karyotypes of the eight Mediterranean species are known; all of them have the basic karyotype for the Monocelididae. Within the Mediterranean, some sister-group relationships among the Archilina species could be recognized. They are probably the result of independent evolutionary lines from ancestral Archilina species.

    Synopsis of the freshwater Triclads of the Caribbean (Platyhelminthes, Tricladida, Paludicola) (1992)
    In:  Studies on the Natural History of the Caribbean Region vol. 71 no. 1, pp. 1-23

    Description: SLUYS, R., 1992. Synopsis of the freshwater triclads of the Caribbean (Platyhelminthes, Tricladida, Paludicola). Studies Nat. Hist. Caribbean Region 71, Amsterdam, 1992: 1-23. An account is given of the five species of freshwater triclads which are known from the Caribbean region, including taxonomic descriptions, karyological, ecological, and biogeographic information, supplemented with remarks on observations of previous workers and comparisons with similar species. Records of unidentified specimens are summarized. Caribbean freshwater planarians belong to the genus Girardia; the phylogenetic relationships within this genus remain to be resolved. It is argued that present distributional patterns in Caribbean Girardia\xe2\x80\x99s may be the result of vicariance caused by a changing geology.
