    On altitude dependent characters in Albinaria idaea (L. Pfeiffer, 1849), with a revision of the species (Gastropoda Pulmonata: Clausiliidae) (1994)
    In:  Zoologische Mededelingen vol. 68 no. 3, pp. 21-38
    Details
    Publication Date: 2024-01-12
    Description: Several forms of Albinaria idaea (L. Pfeiffer, 1849) have been described as (sub)species from various sites on Mt. Ida (Central Crete). In recent years, however, much additional material has been collected, which made clear that no sharp boundaries exist between these forms. Moreover, several characters proved to be altitude dependent to a certain extent. It may be concluded that on Mt. Ida only a single evolutionary entity can be distinguished, viz. A. i. idaea. On the isolated Mt. Kedros, south-west of Mt. Ida, an undescribed allopatric form was found, which because of its smaller size and differences in altitude dependent characters was given subspecific rank as A. i. amabilis ssp. nov. On the Paximadia Isles, south of Central Crete, a percostate and a finely ribbed subspecies occur allopatrically.\nThe finely ribbed one seems consubspecific with A. i. idaea; the percostate one was recently described as the separate subspecies A. i. pichcapunlla Schultes & Wiese, 1991.

    Description: Two species of Roncus L. Koch, 1873 (Neobisiidae), new to science (R. ciobanmos n. sp. and R. dragobete n. sp.), and one species of Neobisium Chamberlin, 1930 [N. (N). biharicum Beier, 1939], collected in the Movile Cave, southern Dobrogea, Romania, have been described, diagnostic characters illustrated, and their geographic distribution analyzed. In addition, the description of Chthonius (Chthonius) monicae Boghean, 1989 (Chthoniidae), otherwise known only from two females, has been amended. The possible relationships of these species are discussed in view of the importance of some diagnostic characters and of the evolution of their cave habitat.

    Publication Date: 2024-01-12
    Description: The guttulinervis group is proposed for a monophyletic group of four northern New Guinean species of the cicada genus Baeturia St\xc3\xa5l, 1866. B. guttulinervis Bl\xc3\xb6te, 1960, is redescribed and three species (B. biroi, B. inconstans, and B. roonensis) are described as new to science. The phylogenetic position of the guttulinervis group, within the genus Baeturia, is discussed. The distribution of shared characters suggests a sister group relationship with the conviva group. A key to the males is provided and a map of distribution is presented.

    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.

    Revision of the Archiloa genus complex with description of seven new Archilina species (Platyhelminthes, Proseriata) from the Mediterranean (1994)
    In:  Bijdragen tot de dierkunde vol. 64 no. 3, pp. 129-150
    Details
    Publication Date: 2024-01-12
    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.

    Revisionary notes on Negulus O. Boettger, 1889, a genus of minute African land snails (Gastropoda Pulmonata: Vertiginidae) (1994)
    In:  Zoologische Mededelingen vol. 68 no. 2, pp. 5-20
    Details
    Publication Date: 2024-01-12
    Description: The genus Negulus is reviewed; only four Recent species, restricted to continental Africa, are recognized.\nThe genus is extinct in Europe, being only recorded from Tertiary deposits. A key to the shells of the Recent species (all figured) is supplied. The anatomy is as yet unknown. A sinistral shell of N. abyssinicus is described from among a series of paralectotypes in the Leiden Museum, the first such abnormality in the genus (figured). A fair amount of shell material has become available (among which some historical specimens) so that metric data may be compared with greater confidence. Recent occurrence is established/confirmed for Eritrea, Ethiopia, Sudan, Kenya, Tanzania, Zaire, Zambia, Mala\xc5\xb5i, and Bioko (Fernando Poo). The small size of the shell necessitates sampling forest leaf litter, a technique that has not been widely applied in Africa; undoubtedly the genus occurs much more widely in the Afrotropical Region. Pupa obliquicostulata from St. Helena Is. is removed from the genus because of the presence of apertural dentition.

    A monographic review of the Thermosbaenacea (Crustacea: Peracarida) A study on their morphology, taxonomy, phylogeny and biogeography (1994)
    In:  Zoologische Verhandelingen vol. 291 no. 1, pp. 1-338
    Details
    Publication Date: 2024-01-12
    Description: In addition to a taxonomic review of the whole order Thermosbaenacea, the general morphology and chaetotaxy are discussed in detail. Due to the results of cuticular staining, and through the study of specimens with SEM techniques also, corrections to earlier interpretations could be made. A chaetotaxic classification, modified after the one of Watling (1989), is presented.\nIn the taxonomic part 34 species are recognized, belonging to seven genera (one new), four families (one new). The examination of adult material of the type species of Monodella, i.e., Monodella stygicola Ruffo, 1949, warranted the creation of Tethysbaena gen. nov., to comprise all other taxa previously included in Monodella. Transferred to Tethysbaena are: M. argentarii Stella, 1951; M. halophila S.L. Karaman, 1953; M. relicta P\xc3\xb3r, 1962; M. sanctaecrucis Stock, 1976; M. somala Chelazzi & Messana, 1982; M. atlantomaroccana Boutin & Cals, 1985; and M. scabra Pretus, 1991. Additionally 15 new species of Tethysbaena are described: Tethysbaena juriaani spec. nov. (type species of the genus); T. gaweini spec. nov.; T. haitiensis spec. nov.; T. juglandis spec. nov.; T. lazarei spec. nov.; T. tinima spec. nov.; T. coqui spec. nov.; T. colubrae spec. nov.; T. scitula spec. nov.; T. calsi spec. nov.; T. stocki spec. nov.; T. tarsiensis spec. nov.; T. vinabayesi spec. nov.; T. aiakos spec. nov.; and T. siracusae spec. nov. The genus Tethysbaena can be divided into six species-groups. One new family, Tulumellidae, was erected for the species of the genus Tulumella Bowman & Iliffe, 1988. A second species of Limnosbaena Stock, 1976 (Halosbaenidae) is reported, but remains undescribed due to the severe damage of the single specimen available. A lectotype is designated for Theosbaena cambodjiana Cals & Boutin, 1985 (Halosbaenidae). All species are discussed with full reference to former publications, distribution, and habitat.\nVia a stepwise approach a hypothesized comprehensive phylogenetic tree is constructed with the PAUP computer program.\nIn the biogeographic part, it is suggested that the actual distributions of the various thermosbaenacean species are the result of vicariance. The distributions are used in reconstructing origins of old tectonic plate fragments of the Tethys Sea belt, in particular those in the northern Caribbean region.
