Description
Carapace distinctly broader than long, convex, perfectly smooth. Front a little prominent beyond the well pronounced supra-orbital angle, divided into two broad lobes. Its breadth is barely a third the greatest breadth of the carapace. Antero-lateral borders curved, cut into 5 blunt lobes, of which the first and last are the smallest. Orbits large, their major diameter nearly half the width of the inter-orbital space, their upper border entire, though traces of the two sutures may be visible. Chelipeds rather longer than the carapace; a small lobule at the far end of the anterior border of the arm, inner angle of wrist stoutly spiniform, hand smooth except for a tiny tubercle in front of the apex of the wrist joint. First 3 pairs of legs slender; merus of last pair less than twice as long as broad, its posterior border ending in an almost dentiform carina. 6th abdominal tergum of male broader than long, broadest in the middle, its sides therefore curved.

This crabs are closely associated symbiotically with various species of Sea cucumbers and Sea anemones.
