Takeda & Miyake, 1969
Carapace elongate pyriform, thickly covered with granules and short hairs. There are four knob-tipped spines in the median line of the carapace, viz. two gastric, of which the anterior one is small, one cardiac and one intestinal. The pseudorostral spines are very slender and widely divergent at tip. The three orbital spines are disposed so as to retain some interval between one another, the general view of the neck being somewhat slender. The hepatic spine small, the branchial region has three spines on the lateral border, the last one being largest and deviated on the dorsal surface; the distance between the 1st and 2nd tooth is larger than that between the 2nd and 3rd. There is a pair of small spines on the posterior margin. No basal tooth on the outer border of the basal antennal segment, the two distal spines also not very prominent.
The chela of the male is somewhat inflated, the immovable finger being armed with a tooth near the base of the cutting edge. All segments of the ambulatory legs are very slender and are fringed with long, soft hairs, especially on the anterior and posterior borders. (Sakai, 1938: 299)
