Dorsal head pores on a bubble-like projection located immediately on head shield. In anterior view, body wide, not compressed laterally, median dorsal keel absent. Rostrum relatively long. Ocellus minute. Lateral head pore elongated. Labrum with a relatively small median keel, broadly rounded, reaching only half of antenna I length. Postabdomen with sub-parallel dorsal and ventral margins, preanal teeth pointed. Spines at base of pre-claw portion predominantly clustered. Antenna I with antennular sensory seta arising in middle. Denticles in rows encircling antennular surface especially small. On antenna II, spine situated on proximal segment of exopod somewhat shorter than second segment. Limb I IDL with a remarkably strong hook-like seta, the smallest IDL seta especially fine and short. IDL with 6–4 distal spinules, 6–10 proximal spinules, 3–6 marginal spinules and 1–2 basal spinules. Eight setae in filter plate II, 8 setae in filter plate III; 9 setae in filter plate IV, 8 setae in filter plate V.
