Shield and cephalic appendages. - Ocular scale with a single terminal spine.

Chelipeds (P1). - Upper margin of right chela tuberculated or spinous. Outer face of left palm regularly convex.

Ambulatory legs (P2-P3). - Dactyl of P3 subequal to propodus or slightly shorter (0.8–1.1). Distal pilosity of P3 dense, forming a brush of setae.

Armament of telson. - Left lobe of telson with a single spine. Right lobe with a single spine (sometimes missing).

Coloration. - Shield orange. Ocular peduncle uniformly colored. Detailed coloration of ocular peduncle: white to pale orange.

Distal antennal peduncle yellow-orange (first two proximal segments dark yellow; flagellum orange). Chela uniformly colored, often grading to paler distally (orange turning to white). Ambulatory legs (P2 & P3) with longitudinal bands (bands merging in more intricate network of reticulations on propodi and dactyls).
