Two New Deep-Sea Tanaidacean Genera, Isopodidus and Cetiopyge (Crustacea : Peracarida) from the Gulf of Mexico
Coastal Sciences, Gulf Coast Research Laboratory
Two new genera and species, Isopodidus janum and Cetiopyge mira were found during an investigation of the deep-sea tanaidacean fauna of the Gulf of Mexico. Isopodidus janum is characterized by an isopod-like body shape and fused abdomen. Cetiopyge mira superficially resembles Expina typica and Mirandotanais vorax due to the enlarged abdomen, but is unique in that the abdomen is laterally compressed in Cetiopyge and cylindrical in the two other taxa. Despite the unresolved nature of tanaidacean phylogeny, both new genera can tentatively be assigned to the family Colletteidae.
