            Female (PBI_OON 21112). Total length 1.79. As in male except as noted. CEPHALOTHORAX: Carapace dark red-brown. Sternum orange-brown. Endites anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus unmodified, patella without prolateral row of ridges. ABDOMEN: dorsum soft portions yellow-reddishbrown ground color, indistinct wide dark netlike pattern and spots, cardiac mark pale. Book lung covers connection of posterior spiracles by distal rim of postepigastric sclerite. Pedicel scutum not extending far dorsal of pedicel. Dorsal scutum absent. Epigastric scutum small lateral sclerites present, without lateral joints. Postepigastric scutum short, only around epigastric furrow, not fused to epigastric scutum, seems to be partly distorted. Spinneret scutum divided into 2 platelets. Colulus small plate with 2 setae. Spinnerets: ALS: not examined; PMS: not examined; PLS: not examined. LEGS: tibiae emerit's glands not examined, tarsi pairs of special setae with distinct flattened clawlike apexes present on tarsi III, IV. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I p0-1-1; II p0-0-1; tibiae: I p1-1-0; v4-2-2; II p0-1-0; v4-2-1p; IV p0-1-0; v1-0-2; r0-1-0; metatarsi: I, II p1-0-0; v2-2-2; IV p0-1-0. Tarsi I to IV superior claws tooth not examined in detail. Trichobothria not examined. GENITALIA: Ventral view: externally conspicuous, probably due to distortion, anterior sclerite and plates distinctly visible through epigastric scutum. Dorsal view: internally with large plate with short lateral extensions, medially protruding, wider than long, covering anterior genitalic process, anterior genitalic process protruding anteriorly, broadly and relatively short stalked with distinctly enlarged apex, originating from smaller plate (there are two small plates), cluster of only few filiform glands present at base of anterior genitalic process, posterior genitalic process (receptaculum) indistinclty pocketlike, weakly sclerotized.
