    Antennule development during copepodite phase of some representatives of Harpacticoida (Copepoda, Crustacea) (1989)
    In:  Bijdragen tot de dierkunde vol. 59 no. 3, pp. 159-189
    Details
    Publication Date: 2024-01-12
    Description: The copepodite antennule development of representatives of 6 harpacticoid families is studied and discussed in detail and that of 8 genera of harpacticoids from 7 families is schematically illustrated. Twenty-seven genera out of 17 harpacticoid families are compared on the basis of own investigations and data from the literature. The origin of newly formed segments can be determined by seta numbers of segments, relative segment length, furrows indicating previous articulations and by the position of the segment which bears the proximal aesthetasc. There are 2 zones of segment formation, both located in the middle part of the first antenna. Normal segment formation takes place distally from the second, aesthetasc-bearing segment from C I to C II and proximally of it from C III to C IV. At least in some species sexual dimorphism of first antennae is present from C II onwards. Females practically show the adult antennular state at C V whereas males undergo important changes from C V to C VI with proximal addition of segments, and often with distal fusions and formation of a unique armature due to adaptations in clasping behaviour. There are specific formation patterns in certain taxonomic groups. E.g. Harpacticidae, Canthocamptidae, Canuellidae and Longipediidae deviate in antennule formation from the rest of Harpacticoida. A higher number of antennular setae of C I which in most of the cases are reduced in C II may be interpreted as indicating an ancestral multisegmented antennule for Harpacticoida.

    Die Aciculidae (Mollusca: Gastropoda Prosobranchia) (1989)
    In:  Zoologische Verhandelingen vol. 252 no. 1, pp. 1-230
    Details
    Publication Date: 2024-01-12
    Description: Our knowledge concerning the recent and fossil species and subspecies of the Aciculidae is summarized. After some introductionary chapters concerning habitat, anatomy, shell morphology and distribution, both in time and geographical, all taxa are dealt with systematically. In total 56 recent species of Aciculidae are characterized, belonging to Acicula (20), Menkia (1), Platyla (25) and Renea (10). In addition 15 fossil species are recognized, in Acicula (5), Menkia (1), Platyla (6) and Renea (3). Four Acicula species and one Platyla species are known from the Miocene to the Recent. Keys enable the identification down to the subspecies level. Synonymy lists are given. The species and subspecies are described and illustrated. Distributional data are summarized on UTMgrid-maps. In total 16 (sub)species are described as new to science, viz. Acicula disjuncta spec. nov., A. hausdorfi spec. nov., A. lineolata banki subspec. nov., A. multilineata spec. nov., A. riedeli spec. nov., Platyla falkneri spec. nov., P. maasseni spec. nov., P. minutissima spec. nov., P. peloponnesica spec. nov., P. pezzolii spec. nov., P. procax spec. nov., P. turcica spec. nov., Renea gormonti spec. nov., R. kobelti albanica subspec. nov., R. paillona spec. nov. and R. singularis ripkeni subspec. nov.\nNeotypes are designated for Acme elegantissima Pini, 1884 and Acme microspira Pini, 1884.\nLectotypes are designated for the following nominal taxa: Acme lineata var. alba Jeffreys, 1862; Hyalacme beieri K\xc3\xa4ufel, 1930; Acme benoiti Bourguignat, 1864; Acme carpatica Wagner, 1912; Acme cryptomena De Folin & B\xc3\xa9rillon, 1877; Acme curtii Wagner, 1912; Acme dupuyi Paladilhe, 1868; Turbo fuscus Montagu, 1803; Acme kobelti Wagner, 1910; Acme letourneuxi Bourguignat, 1864; Acme banatica leptocheila Wagner, 1915; Auricula lineata Draparnaud, 1805; Acicula moussoni Boettger, 1879; Acme moutonii Dupuy, 1849; Acme oedogyra Paladilhe, 1868; Acme (Platyla) oltenica Negrea, 1963; Acme pironae Pollonera, 1889; Acme lineata var. sinistrorsa Jeffreys, 1862; Acme transsilvanica Wagner, 1912; Acme wilhelmi Wagner, 1910.

    Taxonomy, Phylogeny and Biogeography of Mushroom Corals (Scleractinia: Fungiidae) (1989)
    In:  Zoologische Verhandelingen vol. 254 no. 1, pp. 1-295
    Details
    Publication Date: 2024-01-12
    Description: The Fungiidae are mushroom corals that live in sublittoral habitats in the tropical Indo-Pacific.\nTheir habitats are part of coral reefs or other marine substrata, which usually can be found in the proximity of the reefs.\nIn the present taxonomic revision, the family is divided into 11 genera; one of which, Fungia, is subdivided into seven subgenera. A total of 40 species is described and figured, three of which are new to science. One species is renamed.\nThe stratigraphic distribution is given for all the species recorded in fossil state. A tentative phylogenetic reconstruction down to the species level is given. The cladogram that is provided should be considered a working hypothesis and not a sound basis for a completely revised classification and nomenclature of the Fungiidae.\nFor each species the presently known geographic range is mapped. The pattern of species richness in the Indo-Pacific is compared with that of some other taxa and discussed with respect to their distributional patterns. The ranges of the Fungiidae are analyzed with the use of approaches from both historical and ecological biogeography.
