Sternal spines absent. Gnathopod 1basis a little more slender than that of male; carpus slender, subequal in length with propodus or one and one third to one and one half length of propodus, posterior margin without spines; propodus subequal in length to carpus, palm defined by rounded corner. Gnathopod 2basis slender, anterodistal margin without flange.  Habitat.Coral rubble.   Remarks.This species differs from all other Great Barrier Reef species of  Bemlosby the tridentate carpus of the male gnathopod 1.   Distribution.  Australia., Queensland: off North Point, Lizard Island ( Myers 1988b).
