Description. Rostrum longer than carapace; dorsal margin of rostrum with 7 teeth, proximal 3 of which stand upon carapace; ventral margin with 5–8 (mostly 6) teeth. Carapace with well-developed antennal tooth, moderate branchiostegal tooth and feeble pterygostomian tooth. Several tufts of long and dense plumose hairs studded with one row on dorsal carina of carapace and two rows along dorsal medial line of abdomen. Orbital margin single; eye big with distinct ocellar spot; cornea shorter than stalk. Pleurae of fourth and fifth abdominal somites each with small posteroventral tooth; sixth abdominal somite with movable plate articulated near posteroventral angle. Telson with 2 pairs of dorsal spines; posterior margin bearing 3 big spines and 2 small spines.

Basal segment of antennular peduncle longer than combination of second and third segment; dorsal margin of third segment with sharp triangular spine, which apex reaching midpoint of antennal scale; stylocerite reaching distal margin of third segment of antennular peduncle. Distolateral spine of antennal scale exceeding rounded distalmargin of blade. Third maxilliped reaching distal margin of antennal scale; distal end of antepenultimate segment with 2 well-developed protrusions; exopod developed; ultimate segment with 6–8 corneous spines distally. First to fourth pereopods with epipods and arthrobranch.

Adult males showing well-represented secondary sexual character with first pereopod; which so much developed and reaching distal margin of antennal scale; females with first pereopod normally, reaching midpoint of antennal scale; chela about 1.5 times as long as carpus.

Second pereopod reaching distal margin of antennal scale; carpus subdivided into 9–13 articles. Third to fifth pereopods with similar structure. Merus of third or fourth pereopod each with 2 distolateral spines; merus of fifth pereopod with only 1 or 2 distolateral spines; flexor margin of biunguiculate dactylus armed with 3–4 accessory spinules, propodus with row of 8–10 spinules along entire length of flexor margin. Second pleopod in male with appendix masculine moderately stout, about half length of appendix interna.

Coloration in life. Whole body with dark gray spots; antennal scale, third maxilliped and all pereopods with black stripes.

Distribution. South China Sea; from Red Sea to Hawaii Islands, widespread across tropical regions of whole India-West Pacific; coral reefs.
