Carapace somewhat flattened, roughly pentagonal to subcircular in outline and devoid of long hairs except on the grooves. Lobules less convex, flattish but distinctly demarcated by shallow hairy grooves into series of lobules that appear to radiate from mid-cardiac region. Lobulation on posterior third of the carapace incomplete. 2M incompletely divided into two unequal lobes; 1M, 1L-6L, 4M all are distinct; 1P rhomboidal in shape; 2P rectangular; all the lobules of carapace and appendages are closely covered with miliary granules, which are less distinct postero-dorsally and almost indistinct on lower surface. Fine, even, soft and short, yellow felt covered the surface between the granules and the grooves between the lobules. Four shallow subequal lobes present on the antero-lateral sides and the postero-lateral sides are concave, shorter than the former.
The flat lobes covered the carpus, propodus of legs and chelipeds are of same sculpture and texture as that of the antero-lateral part of carapace. Fingers pointed with slight indication of hollowness at tips.
