Medium-sized pontoniine shrimp with swollen, smooth, subcylindrical body. Carapace smooth, with antennal tooth, without hepatic or supraorbital teeth; rostrum well developed, reaching to distal margin of basal segment of antennular peduncle, sharply pointed distally, armed with teeth dorsally, ventrally unarmed. Abdominal somites unarmed, with tergites non-carinate; three last somites small, with feebly developed rounded pleurae, distoventral margins of the sixth somite with posterolateral process. Telson broad, strongly tapering distally, with 2 pairs of small dorsal spines, with straight posterior margin armed with 3 pairs of distal spines. Eyes well developed, with pigmented, rounded cornea; eyestalk swollen, cylindrical, without specific features. Antenna with scaphocerite substantially reduced, not reaching carpocerite, with small but well marked distolateral tooth. Mandible well developed, without palp. Maxillula with bilobed palp, with well developed lacinia. Maxilla with simple, tapering palp, with stout, well developed endites and well developed scaphognathite. Maxillipeds I and II normal, with well developed epipods and exopods. Maxilliped III normal, with rounded epipod and small arthrobranch. Pereiopod I relatively slender, without specific features. Pereiopods II unequal in size and slightly dissimilar in shape; minor pereiopod II generally similar in morphology but smaller in size; major pereiopod II with inner margin of ischium and merus armed with a double row of small sharp tubercles; carpus widening distally, hood-like distally excavate, distal margin not overlapping proximal part of propodus; palm convexive dorsally, proximal part subcylindrical in cross-section, not tapering, finely tuberculate distodorsally, distodorsal margin truncate, forming rectangular distodorsal angle; fixed finger (pollex) triangular, tapering distally and slightly curved, with well marked deep dorsal depression open proximally; movable finger with ventral margin forming a well marked plunger, distoventral angle armed with convex nail-like apex. Pereiopods III–V generally similar, smooth; dactylus biunguiculate, with ventral margin serrated, main unguis smooth, curved and sharp; accessory unguis triangular, sharp, about twice shorter than main unguis; segments of pereiopod V covered with simple setae; ventral margin of propodus unarmed. Pleopods normal; pleopod II of males with appendix masculina bearing 4 long simple setae laterally and a single long apical setae. Uropods not exceeding telson; lateral margin of uropodal exopod straight, with sharply produced distolateral angle and small curved distolateral spine; diaeresis simple.
