A. Milne Edwards, 1873
The carapace is convex fore and aft, thickly covered with short and long stiff hairs which arise singly; the surface is slightly sculptured and sparsely granulated; those granules become larger and sharper near the antero-lateral borders. The front is produced in the middle and bears a narrow deep median sinus, being fringed with several long stiff hairs just near the median sinus; each lateral lobule is small but sharp, and separated from the supraorbital angle by a deep incision. The supraorbital border is setose, spinose laterally, and bears two possible traces of notches, while the infraorbital border is also fringed with setae and spinules, and bears a notch near the external orbital angle; the inner infraorbital angle is not produced but rounded. The inner angle of the basal antennal segment is just touched with the ventral prolongation of the front, its outer angle being raised nearly to the level of the inner infraorbital angle; the second and third antennal segments bear some long stiff hairs each on the outer side.
The antero-lateral border is provided with four spines including the one at the external orbital angle; those spines are rather stout, curved forward and increase in size from the first to the fourth; the second is provided with an accessory spinule behind and below the main spine, the accessory one being as prominent as the subhepatic spinule. The subhepatic region is minutely granulated, one of which is prominent and visible from above but slightly smaller than the spine at the external orbital angle. The postero-lateral border is strongly convergent after some distance from the last antero-lateral spine, its dorsal surface being concave for the reception of the last ambulatory leg.
The chelipeds are distinctly unequal in both sexes; the carpus is provided with short setae mixed with longish ones and with sharp granules on the outer surface, its inner angle being not prominent; the larger palm is also provided with short setae mixed with longish ones and with two kinds of sharp granules in size on the upper and outer proximal surfaces, the larger granules of them being beaded to some longitudinal series; the remainder of the surface, about lower one-third, is smooth and glossy; the smaller palm is nearly like the larger one, but the entire outer surface is covered with granules and hairs; the fingers are clearly toothed on the cutting edges, being toothed more sharply in the smaller ones; each movable finger is considerably longer than the upper border of the palm; the immovable fingers of both chelae are slightly curved downward; the tips of the fingers are curved each other downward and upward, being crossed.
The ambulatory legs are rather long, unarmed and thickly covered with setae or hairs. In spirit the carapace is brick red or blackish brown, and the hairs are yellow. (Takeda & Miyake, 1968a)
