Diagnosis (after Williams & Baba 1989). Rostrum narrowly triangular, exceeding eyestalk by its own or slightly greater length, without lateral spines. Eyes with ovate corneae. Front of carapace with slightly hooked antennal spine lateral to eyestalk followed by concavity ending in small, acute anterolateral angle. Gastric region bearing short setose rugosities behind strong gastric spine at either side of midline, secondary spine lateral to each large spine. Anterior branchial region with less prominent rugosities, lateral margin with strong anterior tooth followed by 4 spines successively smaller in size. Posterior branchial region with moderately developed spine at anterolateral corner, with distinct, transverse rugae. Posterior margin shallowly concave preceded by raised submarginal rim. Abdomen without spines but somites 2, 3 with bold transverse ridges. Chelipeds stout, subequal, with variable rugosities tending to be arranged in longitudinal tracts, ischium with short lateral spine, merus with 3 principal mesial spine, 1 distodorsal spine, distoventral spine, carpus with row of 3 mesiodorsal spines, palm nearly spooned, fingers spooned at apices. Pereopods 2–4 rather long, each merus with crest on dorsal margin ending in distal spine. Carpi with longitudinal spiny dorsal, tuberculate dorsolateral crests, each ending in spine; each propodus slender, with dorsal crest with 2 remote proximal spines, dactyls slender, with row of 10–12 movable spines on flexor margin. Carapace length 6.5–11.6 mm (excluding rostrum).
