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.

Antennula ( Fig. 1E View Figure 1 ) 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 View Figure 1 ) 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 View Figure 2 ) with 1+1 penicils, left mandible ( Fig. 2B View Figure 2 ) 2+1 penicils. 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.
