is clearly distinct from other species in the genus in possessing subchelate peraeopods 3–6, with a somewhat lesser tendency in peraeopod 7. The propodus of these appendages is strongly spined and the dactylus is long, which give the appendage a prehensile appearance. In addition, the telson lobes are not narrowed apically and the strong notch is subapical (vs narrowed apically with a weak to strong, apical notch).
