Description: Maximum body length, male 5 mm, female 4.5 mm.
Brown color. Cephalon with irregular unpigmented spots. Antenna strongly pigmented, fifth article of peduncle with distal portion unpigmented. Pereonites 1-7 with longitudinal unpigmented rows on paramedian region. Epimera 1-7, pleon and telson strongly pigmented.
Body outline as in Fig. 1A; pereonites 1 and 2 slightly directed frontwards, pereonites 4-7 gradually more arched and directed. Dorsal surface densely covered with fan-shaped scale setae (Fig. 1B). Cephalon (Figs. 1A, C) with well-developed lateral lobes, suprantennal line bent downwards in middle, frontal line absent.

Antennula (Fig. 1E) of three articles, proximal and distal articles subequal in length, distal article bearing six lateral aesthetascs in three rows plus apical pair.Antenna (Fig. 1F) reaching fourth pereonite when extended backwards; flagellum of three articles subequal in length, second and third articles bearing lateral aesthetascs, apical organ short bearing two long free sensillae.
Mandibles with molar penicil of seven branches, right mandible (Fig. 2A) with 1+1 penicils, left mandible (Fig. 2B) 2+1 penicils.
