In lateral view body sub-ovoid. In anterior view, body not compressed laterally, median dorsal keel absent. Dorsal head pores located on flat head shield, without any projection of the latter in this region, but a ring of head pores slightly projected above the level of head shield as a very low "pancake", and a surface of major head pore cuticle with a low projection in middle. Lateral head pores as longitudinal slits. Rostrum relatively short for subgenus. Ocellus very small. Labrum with a large median keel, with angled apex, projecting beyond distal end of antenna I. Postabdomen subovoid, with a deep anal embayment. Preanal teeth pointed, a small gap between basalmost teeth and bases of postabdominal setae. Teeth in distal part of postanal margin large, long, singular; spines at base of pre-claw portion predominantly single. Postabdominal claw relatively robust, with two basal spines. Antenna I elongated, with antennular sensory seta arising subdistally, at 1/ 4 antenna I length from end. Denticles in rows encircling antennular surface very small. On antenna II, spine situated on proximal segment of exopod shorter than second segment. Limb I IDL with a strong hook-like seta, the smallest IDL seta short. IDL with 11–15 distal spinulae, 10–16 proximal spinulae and 7–16 basal spinulae. Eight setae in filter plate II, 10 setae in filter plate III, 10 setae in filter plate IV, and 10 setae in filter plate V. Exopodite V with 7 setae. Intestine with a double loop, posterior intestinal caecum absent.

Body more elongated as compared with female. Rostrum short, labral keel small, with a well-developed angular apex. On pre-claw portion of postabdomen there are postanal teeth, distalmost members particularly large, teeth at base of pre-claw portion short, predominantly single. Antenna I elongated, antennular sensory setae short, located subdistally at distance of about 1/4 antenna I length from its distal end; male setae short, located almost medially. Nine aesthetascs distally; additional aesthetascs on anterior and posterior surfaces on antenna I body. IDL of limb I shorter than that in female, with male seta about two times longer than shorthest IDL seta and with two groups few spinules. Limb I supplied by a strong clasping hook with two transverse ridges distally.
