All features as in generic diagnosis. Eyes bilobate, differentiated in a bulbous, dorsoventrally flattened mesial lobe and a smaller, roughly calotte-shaped lateral lobe. Eyestalk fused only with mesial lobe. Reduced ommatidia of mesial lobe face centripetally; modified, in some way functional ommatidia of lateral lobe face laterally, tightly set in parallel orientation, together forming self-contained ribbon. One large tooth close to acute disto-lateral edge of antennal sympod. Antennal scale extends 0.6 times its length beyond antennular trunk and 0.3–0.4 times beyond antennal peduncle. Total scale length three times maximum width; its disto-lateral tooth mesially closely accompanied by two short spines. Thoracic exopod 1 with 9-segmented flagellum, exopods 2, 5–6 and 8 with 10-segmented flagellum (exopods 3–4 and 7 broken). Carpopropodus 2 weakly elongate, longer than merus; reflexed dactylus strongly elongate,> 4 times as long as wide, claw stout and short, ⅖ as long as dactylus. Endopod of uropods with one small slender spine close to mesial margin below statocyst. Telson trapeziform, length 1.7 times maximum width; distal half with continuously converging lateral margins. Proximal 45% of lateral margins without spines, distally remaining portion with about 13–14 normal-shaped spines increasing in length caudally. Transversely truncate terminal margin with very shallow median indentation lined with pair of setae flanked by pair of minute spines; indentation in turn flanked by two pairs of large latero-terminal spines, submedian spines largest, measuring about ¼ of telson length. Telson with total of ≈33 spines and two setae.</paragraph>

). Ocular papilla measuring ¼ of antero-posterior extension of mesial eye lobe. Papilla positioned dorsally at about one-sixth lobe width from mesial margin of mesial eye lobe. Organ of Bellonci ellipsoidal. Without inspection of non-adults, one could erroneously interpret mesial eye lobe as an eyestalk laterally bearing a rudimentary cornea, and thus entire eye as non-lobate.
