Article Reference Resurrection and neotype designation of Pilumnus spinulosus Kessler, 1861 (Crustacea: Decapoda)
ABSTRACT. The scientific name Pilumnus spinulosus Kessler, 1861 is resurrected for the representatives of the brachyuran genus Pilumnus Leach, 1816 (Decapoda: Brachyura: Pilumnidae), occurring along the northern coastal line of the Black Sea. This species has been mistakenly identified as P. hirtellus (Linnaeus, 1761) and recently, based on DNA data, referred to as P. aestuarii Nardo, 1869. Furthermore, a neotype of P. spinulosus Kessler, 1861 is designated as the original material is presently considered as lost. P. hirtellus ponticus Czerniavsky, 1868, P. aestuarii Nardo, 1869, P. hirtellus intermedia Czerniavsky, 1884 are considered as junior synonyms of P. spinulosus Kessler, 1861. РЕЗЮМЕ. Научное название Pilumnus spinulosus Kessler, 1861 восстановлено для представителей рода Pilumnus Leach, 1816 (Decapoda: Brachyura: Pilumnidae), встречающегося вдоль северной бере- говой линии Черного моря. Ранее этот вид был ошибочно идентифицирован как P. hirtellus (Linnaeus, 1761), а позднее, на основании данных ДНК, отнесён к P. aestuarii Nardo, 1869. Видовые назва- ния P. hirtellus ponticus Czerniavsky, 1868, P. aestuarii Nardo, 1869, P. hirtellus intermedia Czerniavsky, 1884 рассматриваются как младшие синонимы P. spinulosus Kessler, 1861.

Article Reference First record of the globally invasive crab, Charybdis hellerii (A. Milne-Edwards, 1867), in Benin, with notes on its taxonomy (Crustacea, Decapoda, Brachyura, Portunidae)
The Indo-Pacific portunid, Charybdis hellerii (A. Milne-Edwards, 1867), is a crab species native to the Indian and Western Pacific Oceans and has previously colonized the Eastern Mediterranean and the Western Atlantic. It is now recorded in the Eastern Atlantic, on the coast of Benin, where a thriving population has established. This invasive and widely distributed species exhibits morphological variations within and between populations, which are discussed in detail. Its current distribution is presented, and its future expansion along the West African coast and future impact on coastal ecosystems and local fisheries are the object of tentative forecasts. Illustrations of sexually mature specimens from different sizes and regions are presented, and their allometric, individual and geographical variations are discussed. A new synonymy and a new account on the taxonomy and the biology of the species are presented. Illustrations of the lectotype and the paralectotype of C. hellerii are also provided for the first time. Charybdis spinifera (Miers, 1884), C. merguiensis (De Man, 1887) and C. vannamei Ward, 1941 are here treated as subjective junior synonyms of C. hellerii. The holotype of C. spinifera and two syntypes of C. merguiensis are illustrated.

Article Reference Cryptic diversity and speciation in endemic Cytherissa (Ostracoda, Crustacea) from Lake Baikal
Lake Baikal (Siberia) is the most ancient and deepest of all ancient lakes on Earth. It holds a (mostly endemic) diversity of thousands of animal species, including a speciose radiation of ostracods of the genus Cytherissa. Applying molecular tools to this crustacean group reveals that several morphological species are actually species clusters. Based on combined 16S and 28S DNA sequence data from thirteen classic Cytherissa species and one subspecies sensu Mazepova (1990), we recognize 26 different genetic Cytherissa species, 18 with morphological variation and eight truly cryptic species. These results suggest that the actual specific diversity of Cytherissa in Lake Baikal might easily be double of what is presently known. Baikalian endemic species most likely live in the cradle in which they originated and this opens perspectives to infer modes of speciation. Our current distribution data of Cytherissa species provide first indications for both geographic (lakes basins and shores) and ecological (sediment type, water depth) separation. Our present data thus provide the first steps towards future, rigorous testing of focussed hypotheses on the causality of speciation through either allopatric isolation or parapatric ecological clines.

Article Reference Biodiversity of ostracod communities (Crustacea, Ostracoda) in a tropical floodplain
Neotropical floodplains harbour both floating and rooted plants and are associated with rich ostracod communities. After dry seasons, flooding causes recruitment in 2 ways: floods bring in allochthonous macrophytes with associated pleuston communities, and these rising water levels rehydrate plants and attached (ostracod) eggs that dried at the onset of the dry season. We analysed the ostracods communities in the Araguaia River floodplain (Brazil) during 2 hydrological periods (dry and rainy) and evaluated the species distribution in relation to abiotic and biotic factors. We compared the ostracod fauna of 6 lakes in the dry and rainy period and 17 lakes in the rainy period. We tested the hypothesis that the highest values of ostracod community attributes (richness, density, and evenness) occur in the rainy season owing to the influx of allochthonous individuals and the rehydration of the dried autochthonous macrophytes. We indeed observed the highest richness and diversity of ostracods in the rainy season; the homogenizing effect of the flood pulse at the onset of the rainy season caused a more homogeneous fauna (lower beta diversity) during that hydrological period. The distribution of species showed a significant effect of both abiotic factors (local) and hydrological period (regional).

Inproceedings Reference Amphibians and Squamates from the Late Pleistocene of Caverne Marie-Jeanne (Belgium)
Archaeological sites usually provide important information about the past distribution of the small vertebrate fauna, and by extension about past terrestrial environments and climate in which human activities took place. In this context, Belgium has an interesting location in North-western Europe between the well-studied zooarchaeological record of Germany and England. The Late Pleistocene (Marine Isotope Stages 3 and 2) locality of Caverne Marie-Jeanne (southeast of Belgium, Ardennes region) yielded a large collection of disarticulated bone fragments and numerous plant, mollusk, and archaeological remains. They have been collected during the first field campaign in 1943 and stored in the Quaternary collections of the Royal Belgian Institute of Natural Sciences. A recent revision of the rich micromammal fauna (31 taxa of insectivores, bats, and rodents among 9897 identified specimens, corresponding to a minimum of 4980 individuals) revealed the presence of the steppe lemming and the European pine vole. We present here the revision of the herpetofauna based on the 1970 Jean-Claude Rage’s study and the revision of the “indeterminate” small vertebrate specimens. It is now by far the largest Late Pleistocene collection of the Belgian institute with more than 20,500 recognized bones of amphibians and reptiles and covering the last 60,000 years. The herpetofaunal list now comprises two urodeles (Lissotriton gr. L. vulgaris and Salamandra salamandra), four anurans (Bufo gr. B. bufo-spinosus, Epidalea calamita, Rana temporaria and Rana cf. R. arvalis), three lizards (Lacerta cf. L. agilis, Zootoca vivipara and Anguis gr. A. fragilis) and three snakes (Natrix gr. N. natrix-astreptophora, Coronella austriaca and Vipera berus). This study highlights the first fossil record in Belgium for L. gr. L. vulgaris, R. arvalis, Z. vivipara, N. gr. N. natrix-astretophora and C. austriaca. This assemblage suggests a patchy humid landscape under colder and dryer climatic conditions in comparison with present ones. The study also underlines the importance to carefully reexamine old collections.
