New Galatheoidea (Crustacea, Decapoda, Anomura) from hydrothermal systems in the West Pacific Ocean: Bismarck Archipelago and Okinawa Trough

Year: 1998

Type: article

Abstract: Two anomuran decapod crustaceans of the superfamily Galatheoidea that are new to science are described from hydrothermally active areas of the western Pacific Océan.Uroptychus edisonicus n.sp., family Chirostylidae, from a volcanic crater on Edison Seamount near Lihir Island, Bismarck Archipelago, Papua New Guinea, is the third species of the genus known to occur in hydrothermally active areas, both of the others coming front the North Fiji Basin.The new species is more similar to non-hydrothcrmal congeners from the Banda Sea and the central North Pacific Océan than to those known from vent areas.Shinkaia crosnieri n.g.n.sp., family Galatheidae, from active hydrothermal areas in the Okinawa Trough and Edison Seamount is placed in the monotypic Shinkaiinae n. subfam.having similarities to the Munidopsinae, but with distinctive characters of its own including carapace shape and ornamentation, very short (or reduced) epipods on the third maxillipeds, features of thoracic sternum, legs, and dense ventral mat of setae.
