查看更多>>摘要:Four new species of marine infaunal decapod crustaceans are described from Lizard Island, Great Barrier Reef, Australia. Three of them belong to the caridean shrimp family Alpheidae, viz. Athanas shawnsmithi n. sp., Athanas daviei n. sp., and Athanopsis saurus n. sp.; all three were collected from burrows of unknown hosts. The fourth species, Axianassa heardi n. sp. from the burrowing mud-shrimp family Axianassidae, is described based on a male holotype from Lizard Island and an additional female specimen from Moorea, Society Islands, French Polynesia. The presence of a toothed diaeresis on the uropodal exopod and a well-developed epipod on the second maxilliped in A. heardi n. sp. are new characters for the genus Axianassa.
查看更多>>摘要:Two new species of the genus Megophrys are described from historical collections presented by Malcolm A. Smith to The Natural History Museum, London, in the early twentieth century. These specimens were previously misidentified as Megophrys parva, a widespread Asian species apparently comprised of a species complex. Megophrys damrei sp. nov., from the Bokor Plateau in the Cardamom Mountains of southern Cambodia and Megophrys takensis sp. nov., from Ban Pa Che, Tak Province, in western Thailand, are herein distinguished morphologically from all congeners from their respective and neighbouring countries. These, or further specimens representing either species, do not appear to have been reported on by other authors in the past and the conservation status of the two new species remains to be assessed. An attempt to locate both species at and near their respective type localities was successful for Megophrys takensis sp. nov., allowing the documentation of observations in the wild and live colouration.This study highlights the importance of examining historical museum collections often overlooked in recent decades by modem taxonomists.

This work provides an updated checklistof the fish species occurring in the proposed Baia da Babitonga marine protected area (southern Brazil) as well as their abundance, ontogenic stage and conservation status, based on multi-site data collected in shallow water and deeper zones of the mainchannel and from published literature. A total of 152 fish species belonging to 18 orders and 53 families were registered, with 29 species being reported for the first time in Baia da Babitonga. Among the registered species, the exotic blenny Omobranchus punctatus(Valenciennes) was the most unexpected. The most species-rich families were Sci-aenidae (18), Carangidae (15), Engraulidae (9), Paralichthyidae (8), Epinephehdae (8) and Gobiidae (7). Nine species inhabiting Baia da Babitonga are classified asglobally threatened, and 17 species are classified as nationally overexploited; four of these species are on both global and national red lists.
查看更多>>摘要:The status of the monotypic taxon Haplogonopus (Verhoeff, 1941), proposed for a disjunct Tanzanian spirostreptoid, is reviewed in light of two additional species, which despite different peripheral appearances, are referable to this genus on the basisof genitalic features. Haplogonopus inflatannulus Verhoeff is redescribed from topotypic material, the nominal species Charactopygus jeanneli (Brolemann, 1920) is relocated in Haplogonopus (n. comb.), and the new species H. cin-gulatus is described fromthe Rondo Plateau in southeastern Tanzania. A terminology for the modified paraproct structure ("Charactopygus-Bildung") of spirostreptids is proposed.
查看更多>>摘要:A miniature alpheid shrimp, Leslibetaeus caribbaeus n. sp., is described on the basis of a single female specimen collected in Sandy Bay, Tobago, in 1992. The new species is closely related to L. coibita Anker, Poddoubtchenko & Wehrtmann, 2006 from the Pacific coast of Panama, the type species and the only other known species of Leslibetaeus Anker, Poddoubtchenko & Wehrtmann, 2006, differing from it in several morphological characters. With the discovery of L. caribbaeus n. sp., Leslibetaeus becomesa genus with transisthmian (= amphi-American) distribution. In addition, L. coibita is reported for the first time since original description and its range is extended by 400 km southwards. The generic diagnosis of Leslibetaeus is slightly emended.
