Diagnosis Lateral processes short, only as long as width, separated at most by half their diameters. Proboscis a cylinder with distal taper. Abdomen short, not extending to distal rim of first coxae, fourth legs. Chelae short, fingers placed anaxially, with 10 to 12 short teeth on each finger. Palps short, segments 2 and 3 subequal, fourth little more than half length of third, fifth longer, almost as long as third. Oviger typical, fourth segment almost as long as fifth, both with many lateral setae. Strigilis denticulate spines with two lateral lobes per side, terminal claw short. Legs conspicuously setose, with dorsal setae as long or longer than segment diameters. Tarsus short, less than half propodal length. Propodus hardly curved, sole with few longer spines, more shorter spines, no larger heel spines. Claw moderately short, auxiliaries about 0.6 main claw length (Ref. 21563, p. 21).
