(Fabricius, 1798)
Gastric region distinct and fairly distinctly subdivided into three lobes; between it and the front are four pimple-like tubercles standing in a square. Two low indistinct somewhat granular elevations, nearly parallel with the curve of the antero-lateral border, traverse either branchial region; the first, which is the more distinct, can generally be traced across the gastric region also. The surface of the carapace is finely pitted anterior-laterally, but elsewhere is smooth. The front, which is not quite a fifth the greatest breadth of the carapace, consists of two prominent round-pointed lobes, outside of each of which is a prominent rounded tooth separated from the supraorbital margin by a groove.
The antero-lateral border is fairly sharp and is divided into four broad lobes, of which the last two are distinctly, the first two indistinctly acuminate. P1 massive, a little unequal, smooth with some fine and distant pitting: inner angle of carpus bluntly prominent; fingers stout, rather short.
P2-5 stout, smooth, except the upper border which is sometimes microscopically granular: upper border of carpus sparsely, both borders of propodi and dactyli more thickly, setose.
Colours in spirit reddish or brownish yellow with sometimes a fine network of darker markings; fingers black. (Alcock, 1898: 178)
