A. Milne Edwards, 1873
The carapace is rather strongly convex fore and aft, and distinctly divided into regions, those areolae being convex and studded with scattered granules of good size; around each granule a tuft of some rather stiff setae or hairs arise, one or two hairs of each tuft being long, but not entirely disguising the areolation. The front is slightly produced, and cut into two rounded lobes, each lobe bearing a small triangular lateral lobule. The supraorbital border is minutely granulated, setose and bears two small notches, of which the lateral one is indistinct. The inner infraorbital angle is slightly produced and cut obliquely, so that an inclined V-shaped notch is formed between this angle and the basal antennal segment. The inner angle of the basal antennal segment is just touched with the ventral prolongation of the front.
The antero-lateral border is armed with four teeth including the external orbital angle; those four teeth are tipped each with a spiniform granule or spinule; the first, or the external orbital angle itself, is as prominent as the second. The subhepatic region is also armed with a protuberance or stout tooth which is tipped with a granule and bears some accessory granules, being visible from above. The postero-lateral border is much longer than the antero-lateral and moderately convergent.
The chelipeds are unequal in both sexes; the merus is concealed under the carapace; the carpus is armed with scattered conical granules of good size fringed and interspaced with short and long setae or hairs on the onter surface, and armed with a stout spine-tipped tooth at its inner angle; the armatures of the outer surface of the larger palm is nearly like those of the carpus, those granules being distinctly beaded to some longitudinal series; the outer lower surface is smooth and glossy; the hairs and granules on the smaller palm are more accentuated.
The ambulatory legs are comparatively stout and rather densely covered with short and long hairs mixed with very sparse plumose ones; each merus of the first three pairs is armed with a small terminal granule rather than a spine; each carpus usually bears a very small terminal granule.
