Balss, 1933
The carapace is rather strongly convex fore and aft, covered with scant short hairs and with some rows and tufts of longish plumose hairs; the surface is very smooth except for some minute granules or pits and granular ridges, around which the hairs arises, the regions being only slightly defined. The front is slightly deflexed and cut into two truncated lobes by a small median sinus; each lobe bears a small lateral lobule, and is separated from the front and the inner supraorbital angle by the shallow depressions. The eye is large; the supraorbital border is nearly entire and bordered with granules of good size, whereas the infraorbital border is more sharply granulated and bears a distinct notch near the external orbital angle. The inner angle of the basal antennal segment fails to reach the ventral prolongation of the front, and its outer angle is raised just to the level of the inner infraorbital angle; the antennal flagellum is about one and a half as long as the major diametre of the orbit.
The antero-lateral border is well arched and provided with a short granulated ridge and the following three teeth; the first ridge is confluent with less prominent external orbital angle; the first tooth is the most prominent, subtruncated and bordered with granules, being depresssed and bearing its tip anteriorly; the second and third teeth are acute, but not spine-tipped, the latter being the smallest of the series. The subhepatic region is tomentose and bears a small blunt protuberance. The postero-lateral border is a little longer than the antero-lateral, and its dorsal surface is slightly concave for the reception of the last ambulatory leg.
The chelipeds are distinctly unequal. The carpus of the larger cheliped is covered with sharp granules interspaced with short plumose hairs mainly on the upper distal surface, and is armed with a stout tooth at its inner angle and with a supplementary one below the main tooth; the smaller carpus is nearly like the larger one. The palm of the larger chela is thickly covered with sharp granules and with short plumose hairs mixed with some longish ones nearly on the entire outer surface; the smaller palm is also similar to the larger one. The fingers of the larger chela are rather short, stout and bluntly toothed on the cutting edges, whereas those of the smaller one are more sharply and irregularly toothed each immovable finger formes a straight line with the lower border of the palm.
The ambulatory legs are rather slender and smooth. Those segments are covered with fine plumose hairs mainly along the borders, but not armed with any spines. (Takeda & Miyake, 1969c)
