Description. Rostrum short, 2/3 times as long as carapace; distal half slightly descending; reaching third segment of antennular peduncle; dorsal margin with 6–10 teeth; ventral margin with 3–6 teeth. Carapace with with antennal tooth, tiny pterygostomian tooth and bearing with small tooth on gastric region.

Abdominal smooth, Pleurae of fourth and fifth abdominal somites each with small posteroventral tooth. Telson with 2 pairs of dorsal spines; posterior margin with 2 pair of spines and 1 mesial pair of stiff setulose setae.

Eye moderate, cornea slightly longer than stalk. Second segment of antennular peduncle equal in length with third one; stylocerite acute, not reaching basal segment of antennular peduncle; dorsal antennular flagellum without accessory branch.

Antennal scale short, 3.2 times as long as wide; reaching distal end of antennular peduncle; lateral margin straight, ending in spine beyond lamella. Mandible only with molar process, without incisor process and palp. Third maxilliped slender, with exopod; ultimate segment overreaching distal end of second segment of antennular peduncle.

First pereopod beyond apex of rostrum by chela; palm longer than dactylus but shorter than carpus. Second pereopod slender, overreaching rostrum by carpus, which subdivided into 16–22 articles; carpus 2.0 times as long as merus, which subdivided into 9–11 articles; ischium with 1 article distally; chela small, dactylus slightly shorter than propodus.

Third pereopod overreaching rostrum by all or most of carpus; flexor margin of propodus with 6–8 spinules; dactylus biunguiculate, flexor margin with 4 or 5 spinules. Fourth and fifth pereopods similar to third pereopod. Merus of third or fourth pereopod bearing 4–5 distolateral spines; merus of fifth pereopod with only 1 or 2 distolateral spines. Uropods longer than telson; endopod and exopod of equal length.

Coloration in life. Body with thick and thin red longitudinal stripes.

Distribution. China seas; Red Sea, Eastern Africa to Hong Kong, Japan, Philippines, Indonesia, and Australia; sandy sediment or coral reefs in shallow water 0– 60 m.
