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 View Figure 1 ; 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 View Figure 1 ). Cephalon ( Figs. 1A, C View Figure 1 ) with well-developed lateral lobes, suprantennal line bent downwards in middle, frontal line absent. Pleon outline continuous with that of pereonite 7 ( Fig. 1A View Figure 1 ), epimera developed, acute and directed backwards. Telson ( Fig. 1D View Figure 1 ) triangular,lateral sides slightly concave,apex right-angled.

Maxillula ( Fig. 2C View Figure 2 ) inner endite (not drawn) with two hairy penicils and distal margin round- ed; outer endite with 4+4 teeth, inner set cleft, outer margin strongly concave equipped with long setae. Maxilla ( Fig. 2D View Figure 2 ) inner lobe rounded covered with thick setae; outer lobe three times as wide as inner lobe covered with thin setae.Maxilliped ( Fig. 2E View Figure 2 ) base rectangular bearing sparse setae; palp with proximal article bearing two long setae distinct in length; endite subrectangular, medial seta surpassing distal margin, distal margin almost straight.

Pereopod 1 with transverse antennal grooming brush, carpus with distal seta double-fringed at apex; dactylus of two claws subequal in length, ungual seta and dactylar organ simple and not surpassing outer claw.

Pleopod exopods without respiratory structures.

Uropod ( Fig. 3A View Figure 3 ) protopod subrectangular, protopod and exopod grooved on outer margin bearing glandular pores, exopod twice as long as endopod, endopod inserted proximally.

Male: Pereopods 1-4 meri and carpi with dense setae on sternal margins ( Fig. 3B View Figure 3 ); pereopod 7 ( Fig. 3C View Figure 3 ) without sexual dimorphism. Pleopod 1 ( Fig. 3D View Figure 3 ) exopod subtriangular, inner margin rounded, outer margin almost straight bearing five setae;endopod twice as long as exo- pod, distal portion slightly directed outwards. Pleopod 2 ( Fig. 3E View Figure 3 ) exopod triangular, outer margin concave bearing many setae;endopod longer than exopod. Pleopod 3 exopod ( Fig. 3F View Figure 3 ) triangular, outer margin sinuous bearing many setae. Pleopod 4 exopod ( Fig. 3G View Figure 3 ) rhomboid outer margin slightly sinuous bearing many setae. Pleopod 5 exopod ( Fig. 3H View Figure 3 ) rhomboid, outer margin almost straight bearing many setae.
