Description
Female (Figs. 1–2) (n= 3). Idiosoma: length 328 (310–350) and width 207 (183–225). Dorsum (Fig. 1 A).

Posteriad to the dorsal idiosomal shield two pairs of tiny platelets occur. Each of those immediate posteriad to the idiosomal shield carry setae f 1 18 (17–19) and f 2 12 (11–12) each whereas each of the most posterior platelets carry setae h 1 21 (18–23) and h 2 17 (17–18). Ve n t e r (Fig. 1 B). Propodosomal coxal plates not fused. One pair of paracoxal setae occurs on the coxal region IV. The integument bears 1 pair of propodogastral setae and 4 pairs of hysterogastral setae. One pair of paragenital setae occur laterad to the genital valves; 4 pairs of genital setae in approximately almost straight longitudinal row. Gnathosoma (Fig. 1 C–D). Hypostome 151 (145–157) long with 4 pairs of hg -setae [hg 1 21 (20–22), hg 2 20, hg 3 41 and hg 4 9] and and 2 pairs of adoral setae. Three- jointed palp, 92 (87–95) long. Trochanter without setae; femorogenu, 6 sts; tibiotarsus, 4 sts, 1 asl terminal, 1 bladder like apophysis and 1 ventral pointed process. Chelicera 150 long with cheliceral seta 7. Legs (Fig. 2).
