female, laterally setose; apex without long setae. Supraocular eave strongly arching, narrow, defined anteriorly by conspicuous, anterolaterally directed pseudorostral spine located at base of rostrum; postocular margin limited by anterior margin of subhepatic region. Subhepatic region with tubercle on ventral margin. Carapace with moderately developed grooves; hymenosomian groove completely surrounding dorsum, isolating rostrum; cardiac region with short median ridge. Thoracic sternum of male broadly curved anteriorly, defining posterior margin of buccal cavern; sternites 13 forming a triangular plate, with suture 3/4 well marked; sternites 48 enlarged, sutures 4/57/ 8 restricted laterally; pleonal cavity about 0.7 of sternal length, defined laterally by sharp even rim, without locking button. Male pleomeres 1, 2 free, 3, 4 fused (suture between somites 34 clearly discernible), 5 free, pleomere 6, telson fused. Thoracic sternum of female twice as wide as long, with paired vulvae anteriorly on membranous medial area; with paired branchiosternal canal apertures posterolaterally on sternite 8. Pleon of ovigerous female deeply excavate, grossly swollen, pleomeres 1, 2 free, 36, telson functionally fused, though sutures separating somites clearly defined. Antennule with relatively narrow basal article; interantennular proepistome short, narrow, sharply carinate. Epistome oblique, anterior margin produced under eyes, antennae, posterior part nearly perpendicular, posterior margin forming buccal cavern slightly produced medially, sinuous on either side of narrow median notch. Eyestalks with minute tubercle on anterior margin. Maxilliped 3 endopod, exposed exopod fully covering lateral half of buccal cavern; lateral length of ischium-merus twice as long as maximum ischium width; merus with slightly expanded anterolateral lobe. Cheliped in males 2.5 as long as carapace length, with swollen propodus, fingers with narrow proximal setose hiatus when closed, cutting edges each with row of low, blunt teeth, dactylus with prominent tooth remote from other teeth proximally. Ambulatory legs slender, elongate (pereopod 2 less than 3 times as long as carapace length), with articulation between propodus, dactylus not supported by broad plate on each side; dactyli each with row evenly spaced, backwardly directed spines on flexor margin; dactylus of pereopod 2 gently curving, those of pereopods 35 more strongly curving. Gonopod 1 with swollen base; narrow distal part strongly twisted, sharply curved ventrally over proximal third, tapering distally to curved apex, distal part directed ventrally, hooking inner side of fused distal pleonal segment. Gonopod 2 strongly flattened, subrectangular in general outline, with slender distomesial projection with truncate apex. Female pleopods 25 biramous.
