Rostrum short, compressed and directed downwards, apex slightly curved upwards, it reaches about to the end of the antennular peduncle, dorsal margin with 3 teeth and ventral margin convex and unarmed. Antennular peduncle with stylocerite broad, short and acute, almost reaches the half this segment and with anterolateral spine extremely small. Scaphocerite is small, with distal tooth almost reaches the apex of lamella. Carapace with antennal spine. Mandible without palp. First pereopods overreaching scaphocerite with carpus and chela, fingers longer than palm or slightly longer. Second pereopods unequal in shape and size. Major pereopod overreaching scaphocerite with carpus, finger smaller than palm, dactylus with a large tooth which fits into a depression in the cutting edge of the fixed finger. Minor pereopod overreaching scaphocerite with chela, finger with a tooth in the cutting edge. Third to fifth pereopods with bifid dactyli. Abdomen smooth, the pleura of first five somites is broadly rounded. Telson with 2 pairs of dorsal spines and 3 pairs of spine on posterior margin.
