Diagnosis. Exoskeleton membranous, smooth. Rostrum short, with dorsal tooth, acute apex, extending posteriorly as mid-dorsal carina. Carapace with suborbital tooth rounded, low antennal tooth, branchiostegal tooth strong, extending posteriorly into carina, pterygostomian margin rounded, cervical, postcervical grooves widely separated on dorsal midline; antennal, branchial carinae extending posteriorly, meeting hepatic carina. Eye pigmented, with tubercle on eyestalk. Stylocerite short, with wide base. Scaphocerite rounded, scale exceeding lateral tooth. Kink in flagellum of antenna. Second maxilliped flattened, setose. Third maxilliped longer than second, flattened, setose; dactyl flat, twisted; with exopod, podobranch. Pereopods 1–3 chelate, sturdy, with epipods, podobranchs. Pereopods 4, 5 slender, with simple dactyls. Abdominal somites with small grooves, pleura blunt to rounded. Somite 6 with dorsal carina. Telson shorter than uropods, narrow, truncate, with 2 pairs movable spines, dorsal groove. Total length 58–64 mm.
