. Small stenopodidean shrimp with slender, laterally compressed body. Carapace densely covered with scattered spines arranged in longitudinal rows. Cervical groove distinct, very deep at dorsum of carapace. Rostrum long, compressed, dorsally and ventrally dentate. Antennal spine strong; hepatic spine, supraorbital spine, branchiostegal spine and pterygostomial spine present. Pleon feebly spinose; first 3 pleomeres dorsally with transverse ridges provided with small spinules, last three pleomeres with few oblique rows of small spinules. Telson narrow, lance-shaped with median groove flanked by 2 longitudinal spined carinae; lateral margin with medial spine; posterior margin ending in 2 distinct posterolateral teeth between which, margin somewhat rounded with small median denticle. Eyes well developed with globular, pigmented cornea. Dorsal surface of eyestalk with few spines near base of cornea; submarginal spines partially overlap cornea. Antennular peduncle with strong, acute stylocerite on outer margin; inner margin with broad, subrectangular process and setose scale-like projection distodorsally. Antenna with well developed, narrow scaphocerite with serrate outer margin, 2 dorsal longitudinal carinae. Mandible with fused molar and incisor processes; palp 3- segmented. Maxillule with broad proximal endite, rounded distal endite and simple setose endopod. Maxilla with slender endopod, bilobed basal and coxal endites, scaphognathite slender, well developed. First maxilliped with 3-segmented endopod; basal endite broad, coxal endite feeble, bilobed; exopod well developed; epipod well developed, bilobed; arthrobranchs absent. Second maxilliped with distal segments of endopod distinct; coxa and basis reduced to rounded lobes; propodus with prominent ventral hook proximally; exopod well developed. Third maxilliped with strongly developed, slender endopod; propodus with weak setiferous organ; carpus, merus and ischium spinulate; exopod well developed. First 3 pereiopods slender, chelate. First pereiopods with weakly developed carpo-propodal setiferous organ; pincers of chela long, slender, palm slightly swollen. Third pereiopods larger than first and second, with slender chelae and spinulate meri, carpi, propodi and dactyli. Fourth and fifth pereiopods long, slender; carpus and propodus distinctly segmented; propodus with movable ventral spines, lacking on carpus; dactylus long, uniunguiculate. Pleopods without appendices internae, biramous except first pair; basipodites ventrally with spines. Uropods normal, exopod and endopod laterally serrated; dorsal surfaces each with 2 carinae, 0–1 spinules on exopod, row of 3– 7 spinules on endopod.
