Stomatopod Crustaceans from Mayotte Island (Crustacea, Hoplocarida)

A collection of stomatopods assembled during the KUW 2009 expedition to Mayotte Island and deposited in the Muséum national d’Histoire naturelle Paris is studied with a review of previous records from Comoros and Mayotte Island. In total 14 species are recognized 3 of them being new records for this region. A brief comparison with other regions studied for stomatopods indicates that sampling is still insufficient in Comoros and Mayotte and that dozens of species remain to be inventoried in that region.

The Crabs from Mayotte Island (Crustacea, Decapoda, Brachyura)

A collection of crabs assembled during the KUW 2009 expedition to Mayotte Island and deposited in the Museum national d’Histoire naturelle Paris is studied. In total 202 species are recognized, 138 of them being new records for the Island and a list of brachyuran crabs is documented and illustrated with photographs. A complementary list of all crabs previously in taxonomic literature from Mayotte and its nearest Islands (Comoros Islands, Glorieuses Islands and marine banks of Zelee, Geyser and Leven) is also provided. In total 298 crabs are identified from the region, the richness of this fauna is discussed with zoogeographic considerations and the prospects for further studies are outlined.

A new sinistral turriform gastropod (Conoidea: Mangeliidae) from Taiwan

The examination of six specimens of a most peculiar sinistral turrid species from Taiwan housed at the Muséum National d’Histoire Naturelle Paris (MNHN) led us to the recognition of a new species. These specimens resemble members of the Oenopotinae Bogdanov, 1987 recently placed in the Mangeliidae P. Fischer, 1883 (Bouchet et al., 2011; Puillandre et al., 2011).

Lectotype designations for Ptychoderini species (Coleoptera, Anthribidae, Anthribinae) of the Muséum National d'Histoire Naturelle

Based on a study of the type material housed in the Museum National d'Histoire Naturelle Paris, lectotypes are designated for the following species: 1) described by Jekel in 1855 - Ptychoderes columbianus, P. callosus, P. mixtus, P. antiquus, Hypselotropis batesi, Ectatotropis conicollis, and Tropipygus speciosus; 2) described by Thomson in 1858 - Phloeotragus sparsutus. The following species have the type specimens illustrated: Ptychoderes mixtus, lectotype female; P. tricostifrons, holotype male; Hypselotropis speciosa, lectotype male; Phloeotragus sparsutus, lectotype male and paralectotype female.

Isanthus Homolophilussp. nov. (Isanthidae: Actiniaria: Anthozoa) from French Polynesia

A new deep-water Actiniaria species,Isanthus homolophilussp. nov. is described from the French Polynesia. Morphological and ecological differences between the new species and the other known species of the genusIsanthusare discussed. The distinct morphological characteristics that distinguishI. homolophilus, are the presence of a tentaculated columnar margin, the tentacle number (84–96), and its cnida biometry. A further ecological characteristic is the distinct symbiotic relationship that the anemone exhibits towards the decapodHypsophiys inflata.During the biological researches of the ‘Service Mixte de Contrôle Biologique’ (SMCB) in French Polynesia (1986–1990) at depths ranging from 100 to 1120 m, a symbiotic association between a deep-water homolid crab,Hypsophrys inflataGuinot & Richer de Forges, 1981 and a sea anemone of the genusIsanthus(Actiniaria: Isanthidae) was collected. Even though this association was described by Guinot et al. (1995) and Chintiroglou et al. (1996), no concise description of the anemone is given. Thus, the goal of the present study was to provide a detailed description of the new anemone species and compare it with other species of the Isanthidae Carlgren, 1938 family.The methodology followed in our investigation was that of Doumenc & Foubert (1984) and Doumenc et al. (1985). Nematocyst nomenclature used was as proposed by England (1991). Abbreviations: MNHN (Museum National d'Histoire Naturelle Paris).
