Rostrum sharp, unarmed, reaching to middle of second segment of antennular peduncle. Antennal spine fused with inferior orbital angle. Pterygostomian margin with a spine. Telson normally with two pairs of dorsal spines and its distal margin rounded, with no posteromedian projection. Eyes with cornea strongly reduced, with a small spot of pigment. Posterior end of caridean lobe of first maxilliped truncated, with no long curved setae. Exopods present on all pereiopods, epipods on first four pereiopods. First pereiopod with carpus excavated deeply anteriorly, twice as long as high, slightly longer than merus but shorter than chela; finger as long as palm. Second pereiopod with carpus excavated anteriorly, four times as long as high, longer than merus and chela, finger longer than palm. Third pereiopod with propodus more than 2.5 times as long as dactylus, dactylus ending in two claws, flexor margin with three spines. Fifth pereiopod with propodus more than twice as long as dactylus. Endopod of male first pleopod with an appendix interna at its anterior margin. Appendix interna of male second pereiopod longer than appendix masculina. Uropodal diaeresis with one long spine.
