Body length 2.56 mm. Prosome slightly depressed; maximum width 560 μm across fourth pedigerous somite. Prosome 1.08 mm long, occupying 41% of body length, gradually broadening distally; cephalosome 351×425 μm; first to fourth pedigerous somites 68×431, 154×480, 203×505, and 283×560 μm, respectively. Urosome 5-segmented; fifth pedigerous somite about 220×440 μm, genital somite (Fig. 6C) 1.40 times longer than wide (578×412 μm); small copulatory pore visible on proximal ventral surface.

Caudal ramus (Fig. 6D) 2.53 times longer than wide (81×32 μm), 0.44 times as long as anal somite, with slightly convex inner margin: armed with 6 small setae (1 lateral and 5 distal); lateral seta positioned at 47% of ramus length; largest of distal setae 47 μm long, 0.58 times as long as caudal ramus, all other setae shorter than width of ramus at base. Rostrum absent. Antennule (Fig. 6E) short, 5-segmented; all segments wider than long; armature formula 5, 8, 5, 5+aesthetasc, and 12+3 aesthetascs; all setae naked; shorter setae usually broadened; aesthetascs small.
