Description. Rostrum with ventral blade conspicuously developed, present triangular in lateral view, apically sharp; much narrower and longer in male than in female; number of tiny teeth of rostrum greatly changed; dorsal margin with normally 7–22 teeth, ventral margin with 6–11 teeth. Carapace bearing small tooth on gastric region, being smooth on postrostral and posterior medianpart; antennal spine present and branchiostegal margin denticulate with 8–13 spinules. Abdomen smooth, six somite 0.6–0.8 times as long as telson; telson with 2 pairs of dorsal spines; acute posterior margin with 2 pairs of spines.

Eye short, reaching distal end of first segment of antennular peduncle. Antennular peduncle short, about 1/3 times as long as carapace; only first segment with small marginal spine; stylocerite wide and rounded. Antennal scale being 4 times as long as wide; ending in sharp point. Third maxilliped overreaching midpoint of antennal scale, with an exopod, ultimate segment with 8 or 9 corneous spines distally.

First 4 pairs of pereopods with epipods. First pereopod reaching distal end of first segment of antennular peduncle, dactylus shorter than palm. Second pereopod slender, reaching beyond midpoint of antennal scale by chela; dactylus slightly shorter than palm; carpus divided into 3 articles, of which middle one longest, longer than combination of rest two articles. Third pereopod longest, reaching distal margin of antennal scale; propodus 3 times as long as dactylus, which flexor margin with 3–5 spinules; flexor margin of propodus with 5 or 6 spinules; merus with one spine on distolateral margin. Fourth and fifth pereopods in similar structure with third one. Uropods as long as telson, outer branch of uropod with movable spine along suture.

Coloration in life. Body in red brown with black and white spots.

Distribution. From Bohai Gulfto northern South China Sea; India, Burma, Japan, Philippines, Indonesia; often associated with medusae.
