A key to Chinese species of Henricia and photos are provided. Species diversity of echinoderms in China seas is briefly discussed.
查看更多>>摘要：We describe a new species of the genus Speleonectes (Crustacea, Remipedia, Nectiopoda) from an anchialine cave on Grand Bahama Island in the northern Bahamas. Speleonectes williamsi n. sp. is morphologically highly similar to Speleonectes emersoni from the Dominican Republic. However, morphological differences between the two species were detected in dissected body parts, such as the setal patterns of the antennae and trunk limbs, the terminal claws of maxillae and maxillipeds, and the frontal filaments.
查看更多>>摘要：Gastrotricha is a small phylum of acoelomatic aquatic invertebrates common in both marine and freshwater environments. The freshwater gastrotrich fauna of Sweden is poorly known and so far only 20 species have been reported. In this study two species,Heterolepidoderma joermungandri n. sp. and H. trapezoidum n. sp., are described as new to science. Moreover, 9 species are presented as new to the Swedish fauna. Additional taxonomic information is also given for 4 species previously reported from the country. In total 7 genera of two families, Chaetonotidae and Dasydytidae, are presented and the number of reported freshwater gastrotrichs from the country is increased to 31.

Synonymies are based on morphological data from specimens recently collected compared with the recovered type of M. lacteovittatus, and the types M. correal and M. zenzesi, as well as data from original descriptions. The male of Miagrammopes guttatus is redescribed and the female is described for the first time. Lectotypes are designated for M. correal and M. lacteovittatus.
查看更多>>摘要：Sawfishes (Pristidae) are large shark-like batoids with a distinctive flattened, greatly elongated rostrum armed on each side with a row of large transverse teeth. Two genera and at least four species occur in the Indo-West Pacific, of which Anoxypristis cuspidata (Latham, 1794), Pristis microdon Latham, 1794 and P. zijsron Bleeker, 1851 have widespread distributions and P. clavata Garman, 1906 appears to be restricted to northern Australia (Compagno & Last, 1999; Last & Stevens, 2009; Phillips et al, 2011). All sawfishes are threatened by over fishing and habitat loss, with range reductions and local extinctions reported for several species (Simpfendorfer, 2000; Monte-Luna et al, 2007; Last & Stevens, 2009; Wueringer, et al 2009; Phillips et al, 2011). All Indo-Pacific sawfishes are assessed by the IUCN as Critically Endangered with decreasing population trends (IUCN Red List of Threatened Species, http:// www.iucnredlist.org/, 10 Sep. 2011).
