Description. Body slender. Rostrum with ventral blade conspicuously developed, present rectangular with distal end broad, 3–4 times as long as wide in lateral view and 1.5 times as long as carapace; distal 1/3 overreaching distal margin of antennal scale; dorsal and ventral margin straight; upper corner of distal margin with apex convex; dorsal margin with

Abdomen slender and smooth. Telson about 1.5 times as long as sixth somite, with posterior margin pointed. Third maxilliped reaching distal margin of first segment of antennular peduncle; ultimate segment with 9 or 10 corneous spines distally. First 4 pairs of pereopods with epipods.

First pereopod stout, slightly overreaching posterior margin of orbit; dactylus slightly longer than palm; chela about 2.6 times as long as carpus; merus as long as chela. Second pereopod reaching distal end of antennular peduncle; carpus subdivided into 3 articles, of which middle one longest, equal to combination of rest two articles. Third pereopod reaching midpoint of antennal scale; flexor margin of propodus with 2 rows of spinules; biunguiculate dactylus slender, flexor margin with 7 spinules. Fourth and fifth pereopods similar tothird pereopod; merus of last 3 pereopods each with distolateral spine. Uropods as long as telson, outerbranch of uropod with movable spine along suture.

Coloration in life. Green or brown, always with brown or white longitudinal stripes on back; color often changes with surrounding environment.

Distribution. Northern China seas; Red Sea and east coast of Africa, Sabah Island of Malaysia, South Korea, Japan, Indonesia, and Northern Australian waters; 5– 60 m.
