Carapace broader than long, ovate; dorsal surface convex, generally smooth, pitted, regions not clear; branchial regions swollen (Figs 5 A, 7 A). Postorbital and epigastric cristae not confluent, separated by shallow groove (Figs 5 A, 7 A). External orbital angle bluntly triangular, outer margin separated from anterolateral margin of carapace by shallow cleft (Figs 5 A, 7 A). Anterolateral margin of carapace convex (Figs 5 A, 7 A). Orbits large; supraorbital and infraorbital margins smooth (Figs 5 B, 7 B). Exopod of third maxilliped reaching beyond anterolateral corner of ischium, without flagellum (Figs 6 C, 8 C). Thoracic sternites 3 / 4 in male fused except for incomplete groove demarcating suture (Figs 5 C, 6 E, G, 7 C, 8 E, G). Vulvae transversely ovate, relatively closely located to each other, touching suture of sternites 5 / 6 (Figs 6 H, 8 H). Male pleon narrowly triangular (Figs 5 C, 6 E, 7 C, 8 E). G 1 slender, almost reaching or reaching beyond pleonal locking tubercle in situ (Figs 6 G, 8 G, 9 A, B, D, E, 10 A-D); terminal segment slender, subconical, bent outwards, relatively short, ~ 0.4 x length of subterminal segment, with distinct groove for G 2 on ventral side, tip subtruncate, gently recurved upwards, dorsal flap absent (Figs 9 A, B, D, E, 10 A-D).
