Description. Rostrum straight or slightly downward, apex only being somewhat curved upward; rostrum slightly beyond tip of antennular peduncle; dorsal margin with 5–7 teeth, of which proximal one or two placedon carapace behind orbit; 1–3, mostly 2, teeth on ventral margin near apex. Carapace smooth and longer than rostrum. Antenna1 spine and pterygostomian spine present.

Abdomen smooth, not forming ridges of grooves. Pleurae of fourth and fifth somites acutely pointed at posteriorangle.

© Zoological Systematics, 40 (2): 107–165 Telson with 4 pairs of dorsal spines and posterior margin triangular with one pair of long plumose hairs and 2 pairs of spines.

Eye cylindrical; cornea with indistinct ocellar spot, shorter than stalk. Antennular peduncle reaching middle point of antennal scale; each segment with marginal spine; stylocerite sharp, reaching distal margin of second segment of antennular peduncle; outer antennular flagellum thicken and setose in proximal 10–29 segments. Scaphocerite long, narrowed distally, being about 2.6–3.5 times as long as wide; outer margin straight, ending in sharp spine.

Third maxilliped and first pereopod with huge secondary sexual differences. In male, hird maxilliped enormously long, reaching with antepenultimate segment beyond antennal scale; ultimate segment slender and elongate, being almost twice as long as carapace, ends in several corneous spines. In female, third maxilliped normal, reaching with whole length or distal two-thirds of ultimate segment beyond antennal scale; ultimate segment shorter than carapace, with seven corneous spines at apex.

First pereopod in female reaching distal tip of antennal scale; while first pereopod in male larger and more robust, reaching distal articulation of penultimate of third maxilliped. Third pereopod overreaching antennal scale by dactylus; merus with 2–5, generally 2–3 outer spines near distal articulation; fifth pereopod reaching distal tip of stylocerite; merus with one subterminal spine.

In male endopod of first pleopod different in shape from following endopods; namely distal 1/4 of it cylinder form with minute coupling hooks, instead of long plumose hairs. Appendix masculine large, near appendix interna of endopod of second pleopod, furnished with long bristles on distal half.

Coloration in life. Carapace with yellowish-brown and light green sloping stripes, abdomen with transversal stripes; eggs brownish green.

Distribution. Bohai Gulf, Yellow Sea, East China Sea; Sea of Japan; living in clear shallow water area, often attached to seaweed.
