Scavenger, taken in baited traps. Remarks. Parschisturella carinata is the most distinctive species in the genus because of the parachelate first gnathopod with its serrate palm. It is the only species with a distict constriction on the outer ramus of uropod 2. It shares a rounded boss on urosomite 1 with the Ausralian species P. martrudan and P. piloti . It shares a well developed spine on the posteroventral corner of epimeron 3 with the Australian species P. martrudan and P. medora . Distribution. Southern Ocean.
