Description
Wrists and hands with large granular warts as well as granules. Front bilobed, the edges of each lobe concave and the angles in the form of granular tubercles.

Carapace is covered with a fine close down. On either side of the carapace just behind the front are two granular transverse elevations. The front is really bilobed, but as each lobe has a deeply concave edge and both angles surmounted by a granular tubercle, it appears four-lobed. The three grooves near the outer angle of the orbital margin are very distinct. The upper surface of cheliped arm is covered with pearly granules. The upper and outer surfaces of the wrist, and the upper, outer and much of the inner surfaces of the hands, are covered with pearly granules. The fingers of larger cheliped are stout, truncated, blunt pointed and somewhat hollowed at tip. Those of the smaller cheliped, though hollowed, are thin and pointed. The legs are thickly covered with fur and long adherent silky hairs, beneath which the whole dorsal surface of the last four joints is granular.
