(Linnaeus, 1767)

The carapace anteriorly broadened, thickly covered with granules, which are tufted with curled hairs as in Stilbognathus cervicornis. The hepatic regions are markedly depressed and also the lateral portions of the intestinal region.
The pseudorostral spines are very short and vertically deflexed, widely divergent at tip. The supraocular eaves are extremely dilated laterally, having an appearance of antlers, their anterior and posterior angles being produced into a knob-tipped spine, their anterior ventral angle also produced into such a spine. The eyestalks are very long and their tip exceeds the said spines of the orbital margin.
The postocular spine is very long, its tip exceeding the tip of the orbital spines, having usually two or three tubercles, but in the Japanese specimen only one or two tubercles occur on the anterior border near the tip.
The gastric region has two spines one behind the other; the intestinal region has one spine near the posterior border. The branchial regions have each two spines on the lateral border; all these spines are knobbed at tip. Chelipeds are as slender as the ambulatory legs, each segment being unarmed. Ambulatory legs are thickly covered with two sorts of hairs, of which the curled hairs are found on the entire surface and the long hairs mainly on the anterior and posterior borders.
Abdomen of male consists of seven distinct segments, that of female of five. (Sakai, 1938: 251)
