), no visual elements; eyes converging mesially, dorsoventrally compressed by a factor of 1.3–1.5. Each eye rudiment with two basally wide ocular papillae; length of distal papilla 28–31% of length of antero-posterior extension of eye rudiment, proximal papilla 21–26%. Distal papilla mid-rostrally forming part of anterior margin, and proximal papilla at distal third from mesial margin. Disto-lateral edge of antennal sympod produced into one large tooth. Antennal scale with setose mesial margin and bare lateral margin up to remaining, available scale length (apex broken). Mouthparts normal, labrum rostrally rounded. Thoracic exopod 1 with 9-segmented flagellum, exopods 4–8 with 10-segmented flagellum (exopods 2–3 broken). Three carpopropodus segments separated from each other by oblique articulations in thoracic endopods 5 and 8 (endopods 3–4 and 6–7 broken). Female with three pairs of oostegites contributing to outer wall of marsupium, first pair small but functional. Endopod of uropods with one minute spine on mesial margin below statocyst. Telson linguiform, distal half subtriangular with nearly continuously converging lateral margins, narrow terminal margin flattened; telson length 2.2 times maximum width. Lateral margins proximally bare, their distal 4/7 armed with 29–32 normal-shaped spines, distally gradually increasing in size; terminal margin with small median spine flanked by slightly subterminally inserting pair of setae, in turn flanked by two pairs of large spines, among which submedian spines largest, only ≈ 1/15 of telson length. Telson with total of ≈ 66 spines and two setae.
