Major chela carried with chela twisted back toward body in life. Minor cheliped reaching only to proximal half of palm of major cheliped; fingers longer than palm, with few tufts of stiff setae, small teeth; carpus subtriangular. Pereopods 2, 3 stout, with spinules on propodus, ending in short claw-like dactyl. Telson with distinct transverse suture; posterior lobes separated by median cleft, terminal margins oblique, armed with 3–5 strong teeth, smaller teeth. Shield length to 6.2 mm.
