Ischia unarmed (first leg) or 1 or 2 spines (second and third legs) on flexor margin. Meri somewhat compressed latero-mesially, elongate oval, tapering distally; extensor margin weakly crenulated; distoflexor margins of lateral and mesial surfaces without lobes or spines; flexor surface concave, lateral flexor margin crenulate, mesial flexor margin with spines and protuberances, spines of second and third legs strong. Carpi elongate, with small pits and very short striae on surfaces; disto-extensor and distoflexor corners unarmed, narrowly rounded. Propodi 1.4–1.6 times as long as dactyli, 2.6–3.0 times as long as high; lateral and mesial surfaces with scattered, small pits; extensor margin nearly smooth; flexor margin with 5 or 6 corneous spines, distal pair of spines subequal in size. Dactyli each terminating in curved, bifurcate claws, flexor claw subequal in length to but stouter than extensor; flexor margin with 2 or 3 small corneous spines on slightly produced bases, spines much smaller than terminal claw.
