Hilgendorf, 1879
The entire animal is dorsally covered with long flexible hairs but the outline of carapace and appendages is not concealed by them. The regions are weakly defined, the surface near the antero-lateral borders being covered with very fine granules. The two frontal lobes are well convex and the median frontal sinus deeply V-shaped. The entire orbital border is finely denticulated. The antero-lateral borders are armed with four acuminate spines, the first or external orbital one is somewhat smaller and has some additional spines below it.
The palm of major cheliped is tuberculated only on superior surface and on the proximal portion of the outer surface, the remainder of the surface being smooth and glabrous; the palm of minor cheliped has rather erect tubercles which are arranged in longitudinal series. The ambulatory legs are slender and long for this genus; the merus bears a spinule at the distal end of the anterior border; the distal half of anterior border of the three anterior pairs is also armed with three to five slender spines.
