Fixed finger with weakly or moderately curved distal claw; dorsal surface with scattered short simple setae; cutting edge with row of small, rounded and subtriangular teeth (female) or unarmed except for large proximal tooth with marginal tubercles (male); ventral surface with few short simple setae along cutting edge. Dactylus 0.4–0.5 length of chela, with strongly curved distal claw; dorsal surface nearly smooth; dorso-extensor margin rounded (male) or with rugose ridge (female); cutting edge concave, with row of small, rounded and subtriangular teeth (female) or unarmed except for broad proximal tooth (male); ventral surface with few short simple setae along cutting edge.

Meri somewhat compressed lateromesially, elongated ovate, decreasing in size posteriorly; extensor margin unarmed but slightly crenulated, weakly convex; distoflexor margins of lateral and mesial surfaces without lobes or spines. Carpi moderately elongate; lateral surface with longitudinal rows of short rugae on extensor half; disto-extensor and distoflexor corners unarmed, narrowly rounded. Propodi 1.6 times as long as dactyli, 3.4 times as long as high; extensor margin slightly crenulated; flexor margin with 4 corneous spines, proximal spine smaller than others, distal paired spines subequal in size. Dactyli each terminating in weakly curved, bifurcate claw, flexor claw stouter but shoter than extensor claw; flexor margin with 2 small corneous spines.
