Diagnosis. Based on male. Gnathopod 2 propodus ovate, palm extremely acute, convex, extending about 75% of posterior margin, with rounded protuberance near dactylar hinge, with large distal sinus, with two rows of robust setae along entire margin, posteroproximal corner without spine; dactylus slightly longer than palm. Pereopods 6– 7 much longer than pereopods 3–5. Pereopod 6 much longer than pereopod 7; basis expanded posteriorly. Pleonites 1–2 each with pair of posterodistal spines. Pleonite 3 with paired vestigial posterodistal spines. Uropod 3 ramus longer than peduncle, 3.8 x as long as broad. Telson  entire apically truncated with about 10 apical robust setae on each side.

Distribution. Namibia. Walvis Bay, ~ 25°55’S 14°32’E ( Schellenberg 1925); Lüderitz Bay, ~ 26°39’S 15°09’E ( Schellenberg 1925; Penrith & Kensley 1970); Shearwater Bay ( Griffiths 1974a); Skeleton Coast, 21°38’38”S 13°55’17”E and 26°44’09”S 15°05’40”E ( Coleman & Leistikow 2001); Orange River mouth, ~ 28°37’56.23”S 16°27’16.88”E ( Griffiths 1974a).
