DIAGNOSIS.—Integument smooth, not pitted, on lateral areas of carapace and abdomen; rostrum not overreaching antennal scale, shallow, ventrally concave, rostral formula 1 + 6–9/2, posteriormost tooth somewhat isolated from remainder of dorsal rostral series, situated slightly anterior to level of hepatic spine; carapace without supraorbital or postorbital spine, hepatic spine not noticeably larger than antennal spine, arising posteroventral to latter, not extending beyond anterior margin of carapace, orbital angle sinuously and acutely produced, not quite spatulate; abdomen with low, compressed dorsal prominence on 3rd somite, 6th somite fully twice as long as 5th; telson with 2 pairs of dorsolateral spines anterior to posterior margin, both pairs arising in posterior of length; eye with comea hemispherical, not produced distally; antennular peduncle with 1 small distolateral spine on basal segment; antennal scale about 4 times as long as wide, lateral margin slightly concave, distolateral tooth not nearly reaching level of distal margin of blade; 4th thoracic stemite without slender median process; 1st pereopod overreaching antennal scale by length of fingers, latter not pectinate on opposable margins; 2nd pereopod with fingers subequal to palm in length, carpus slightly longer than palm, about 5 times as long as distal width, without distal spines, merus without tooth on flexor margin; 3rd pereopod with dactyl not subdistally truncate, without denticulate lobe on flexor margin, simple, not biunguiculate, flexor margin sinuously concave, propodus with few spinules on distal of flexor margin, not segmented; 5th pereopod reaching to about distal end of antennal scale; uropod overreaching extended telson; maximum postorbital carapace length more than 5 mm.
RANGE.—Seychelle Islands, South China Sea, southern Japan, and Philippines; to a depth of about 130 meters.
