DIAGNOSIS.—Integument smooth, not pitted, on lateral areas of carapace and abdomen; rostrum not overreaching antennal scale, rather shallow, horizontal, rostral formula 1–2 + 7/1, posteriormost tooth somewhat isolated from remainder of dorsal rostral series, situated posterior to level of hepatic spine; carapace without supraorbital or postorbital spine, hepatic spine no larger than antennal spine, arising posteroventral to latter, not extending beyond anterior margin of carapace, orbital angle produced, subovate; abdomen without compressed dorsal prominence on 3rd somite, 6th somite about twice as long as 5th; telson with 2 pairs of dorsolateral spines anterior to posterior margin, anterior pair arising at about mid-length; eye with comea hemispherical, not produced distally; antennular peduncle with 1 distolateral spine on basal segment; antennal scale about 3 times as long as wide, distolateral spine 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; major 2nd pereopod with fingers slightly more than as long as palm, carpus slightly less than as long as palm, about 3 times as long as distal width, without distal spines, merus without distal tooth on flexor margin; 3rd pereopod overreaching antennal scale by about length of dactyl, latter not subdistally truncate, without denticulate lobe on flexor margin, biunguiculate, flexor margin faintly sinuous, propodus with few spinules on flexor margin, not segmented; uropod overreaching extended telson; maximum postorbital carapace length about 2 mm.
