A–C) relatively slender for genus. Chela subtriangular. Dactylus distinctly longer than palm, with scattered setae on surfaces; cutting edge with row of small corneous teeth. Palm with dorsal surface slightly convex, bearing longitudinal row of low, tiny tubercles mesial to midline and few low tubercles along midline; dorsolateral margin delimited by tuberculate ridge extending onto midlength of fixed finger: dorsomesial margin also delimited by interrupted, faintly tuberculate ridge; lateral and mesial faces smooth; ventral surface also smooth, gently convex. Fixed finger with row of small corneous teeth on distal half of cutting edge. Carpus slightly widened distally, 1.7–1.8 times longer than wide; dorsal surface mesially with 1 small distal spine and few low tubercles, laterally with irregular rows of short bristle-like setae; lateral surface smooth, ventrolateral margin unarmed; mesial surface with 2 oblique, low ridges each bearing some long, bristle-like setae, followed by few individual bristle-like setae; ventral surface convex, almost glabrous. Merus unarmed dorsally; ventrolateral margin with 2 small spines in distal 0.2; ventromesial margin unarmed.
