Diagnosis (modified from original report). Small, slender shrimp, body subcylindrical, smooth. Carapace with epigastric tooth, with antennal and hepatic teeth, without supraorbital teeth. Rostrum compressed, short and deep, not reaching distal end of antennular peduncle, dorsally dentate, with 1–2 subapical ventral teeth. Fourth thoracic sternite with finger-like median process. Eyes large, cornea broader than stalk, eyestalk short, stout; accessory pigment spot indistinct. Antennula with stylocerite acutely produced distolaterally, statocyst large, rounded; distal margin with small lateral tooth terminal or subterminal and rounded or obsolete lobe medially; with ventromedial tooth; intermediate and distal peduncular segments elongate; outer flagellum biramous, fused part slender, long. Antennal basicerite with small lateral tooth, scaphocerite far overreaching antennular peduncle, elongate, with distolateral tooth subequal to convex distal margin of lamella; carpocerite short. Mandible with well-developed incisor and molar processes, palp absent. Maxillula with normal palp and endites. Basal endite of maxilla bilobed, palp elongate, scaphognathite ovoid. Maxillipeds normal, with well-developed exopods and epipods; endites on first maxilliped separated by distinct incision, palp setose, caridean lobe small, epipod broadly triangular; second maxilliped with epipod well developed, simple, without podobranch; third maxilliped with merus laterally spinulate, ischium, basis and coxa feebly separated, coxa with rounded lateral lobe, arthrobranch absent or single, rudimentary. First pereiopods slender, fingers simple, subequal or longer than palm, carpus longer than chela, and longer or subequal to merus, coxa with distoventral setose lobe. Second pereiopods feeble, symmetrical, slender, similar to first pereiopods, overreaching latter by chela and distal carpus; fingers simple, longer than palm, carpus almost twice as long as chela or merus. Ambulatory legs long and slender, dactylus very slender, simple, slightly curved, as long as or longer than half of propodus length, unguis acute; propodus slender, distoventral spines small or lacking. Five pleurobranchs present on body wall above bases of pereiopods. Pleomeres with pleurae I–IV rounded; fifth posterolaterally rounded or acute, sixth pleonal segment elongate or stout, as long as or longer than telson. Telson elongate, with 2 pairs of minute dorsolateral spinules; posterior margin subtriangular, with 3 pairs of spiniform setae, lateral spines minute, intermediate longest. Uropodal protopod unarmed, rami overreaching telson; exopod with minute distolateral tooth and longer movable spine medially, diaeresis indistinct or distinct.
