Carapace, chelipeds and legs with pedicled, flat-topped tubercles which at the margins become petaloid; front bilobed, each lobe cut into four petaloid teeth.

Carapace sub-circular, three-fourth as long as broad, convex, well lobulated and divided by broad, deep, smooth grooves into regional lobules. The whole carapace, except the broader grooves between the regions, closely covered with very elegant tubercles, exactly like pin heads in appearance. The exposed surfaces of the chelipeds and legs are covered with ornaments similar to those on the carapace, except at the edges, where they become petaloid. Antero-lateral borders ornamented like the surface, obscurely lobed. Postero-lateral borders about equal in length to the antero-lateral straight. Fingers short, blunt pointed, slightly hollow at tip.

This species identical with Actaea fragifer (white) but the shape and lobular textural pattern of carapace, arrangements of the granules on the carapace and appendages are quite distinctive enough to separate both the species.
