Rostrum reaching beyond antennal scale. Eye rudiments with strong tooth-like anterior projection extending beyond basal segment of antennular trunk; this segment without ventral carina. Antennal sympod with three teeth near disto-lateral edge; median segment of peduncle five times as long as basal segment; scale length four times as long as maximum width. Blade-like extension of clypeus proceeds anteriorly between antennae up to end of second segment of antennular trunk. Uropods without spine. Telson trapezoid not considering terminal incision. Terminal incision ⅐ of telson length, lined all along with densely-set, slender laminae. Lateral margins distally converging; basal 3/10 bare except for small stand-alone spine at ⅕ of telson length from basis; distal 7/10 with discontinuous series of large spines with 1–2 small spines in between; large spines increasing in length distally. Each disto-lateral lobe with two spines, outer spine ⅔ length of incision, inner spine ⅓. Telson with total of ≈ 34 spines and ≈ 35 laminae, no setae.</paragraph>

Proximal portion of oostegites 1–3 on inner face with 5–8, 8–10 and 10–13 long setae, respectively; setae microserrated by series of stiff, acute bristles along distal half. Oostegite 1 with only two additional, plumose setae near terminus. In contrast, oostegites 2–3 with ventral and anterior margins plus part of posterior margin bearing dense series of setae contributing to ventral and caudal, ventilation-pervious closure of marsupium. Proximal setae smooth but numbers of barbs per seta increase distally, yet not attaining configuration of typical plumose seta. Basal portions of dorsal margin without setae in oostegites 2–3. Only oostegite 3 with numerous slender whip setae loosely scattered over its outer face.
