Medium-sized pontoniine shrimp with swollen, slightly depressed subcylindrical body; body and appendages smooth, generally glabrous, distal part of propodi and dactyli of ambulatory pereiopods covered with tufts of simple setae. Carapace swollen, without antennal or hepatic teeth, with inferior orbital angle acutely terminating; rostrum well developed, but short and broad, curved downward, dorsally and ventrally unarmed, reaching midlength of basal antennular segment in females and distal part of basal antennular segment in males, with well developed lateral carina, ventral carina forming broad distinct keel between antennular segments. Abdominal somites unarmed, smooth, with non-carinate tergites; three last pleomeres small, with feebly developed rounded pleurae. Telson stout, tapering distally, with three pairs of small, stout dorsal spines, with posterior margin of the telson blunt armed with two pair of spines and a row of long submarginal setae. Eyes large, swollen, stout, smooth; eyestalk swollen, cylindrical; cornea large, rounded, well pigmented. Antennula and antenna without specific features, slightly reduced; basal antennular segment with well marked ventromedial and distolateral teeth; scaphocerite of antenna well developed, with large acute distolateral tooth separated from blade by distinct notch. Mandible well developed, without palp, lateral margin of incisor process smooth. Maxillula with bilobed palp. Maxilla normal, with pointed simple palp and single distally rounded endite furnished with styliform elongated setae along distal and lateral margins; scaphognathite broad, furnished with short plumose setae. Maxilliped I normal, with earshaped epipod bearing distinct lateral notch, with slender exopod with expanded caridean lobe; basal and coxal endites completely fused; epipod well marked, distally rounded. Maxilliped II with normal rounded epipod and slender exopod overreaching propodal segment; propodus with distolateral margin broadly rounded, with dorsal margin convex furnished with slender setae, dactylar segment slender, about 3 times as long as broad. Maxilliped III normal, with well developed epipod and exopod; ischiomeral segment broad furnished with simple setae along its lateral margins. Appendages robust, unarmed, smooth. Pereiopod I normal, with slender segments and simple non-spatulate fingers. Pereiopods II small and robust, equal in size and shape, with unarmed smooth segments, fingers of chela equal, broad and compressed, about 0.6 of palm length. Ambulatory pereiopods (p-p III

IV) similar, robust, smooth, with simple dactyli, with distal part of propodi and dactyli densely covered with simple setae. Uropod stout, with exopod about 0.6 of endopod length; exopod with bluntly-rounded distolateral angle, without movable distolateral spine. Endopod of pleopod II in males with short appendix masculine, about 1.5 times shorter than appendix interna, without specific features, covered with numerous simple setose setae.

The new genus can be clearly distinguished from all known pontoniine genera by the combination of the following morphological characters: smooth glabrous body, the absence of antennal and hepatic teeth, broad toothless rostrum turned downward, telson with three pairs of dorsal submarginal spines and two pairs of posterior spines, simple non-spatulate fingers of pereiopod I, short and robust equal pereiopods II with equal fingers, simple dactyli of ambulatory pereiopods, short uropodal exopod (about 1.5 times shorter than uropodal endopod), and the absence of movable spine at the distolateral angle of uropodal exopod. The most distinctive feature of the new genus is the presence of three pairs of dorsal submarginal spines on the telson which is a unique feature within the subfamily
