Female. Carapace clearly tapering proximally, almost parallel with only slightly rounded lateral margin, pereonites lateral margin almost parallel. Cheliped basis separated from pereonite-1 by large gap ventrally. Antennule 4-articled. Antenna 6-articled, occasionally fusion line at midlength on article-4. Labrum relatively massive, covered by minute setae, with some longer setae distally. Mandible molar as long as incisor, with a few tubercles gradually elongated into five spines. Labium inner lobe slender (twice as long as wide). Labium outer lobe naked. Maxilliped endites with two short setae and one large conical tubercle. Cheliped massive; carpus only about 1.5 times as long as wide, 0.5 times as long as propodus; propodus large, with well calcified inner margin and strongly serrated keel ventrally; dactylus with strong tubercle on inner margin; unguis large, strongly calcified, as long as dactylus. Pereopods 16 compact; coxa present; merus, carpus and propodus with strong biserrated setae and numerous microtrichia along article. Pleopod rami paddle-shaped, with setae aggregated distally. Uropod endopod 2-articled, twice as long as exopod.
