Major cheliped stout, slightly longer than walking legs; merus relatively smooth, carpus with lateral surface strongly produced ventrally, all surfaces covered with flattened tubercles; hand covered by flattened, plate-like tubercles, palm very broad, dorsoventrally compressed; movable finger with 1 broad tooth, 3 smaller distal teeth, fixed finger with broad tooth, few smaller distal teeth. 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.
