            Female (PBI_OON 37746). Total length 1.55. CEPHALOTHORAX: Carapace orange-brown, without any pattern, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, with rounded posterolateral corners, posterolateral edge without pits, posterior margin not bulging below posterior rim, posterolateral surface without spikes, surface of elevated portion of pars cephalica finely reticulate, sides finely reticulate, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin undulate, rebordered, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae needle-like, present, scattered; non-marginal pars thoracica setae needle-like; marginal setae needle-like. Clypeus margin slightly rebordered, curved downwards in front view, vertical in lateral view, high, ALE separated from edge of carapace by their radius or more, median projection absent; setae present, needle-like. Chilum absent. Eyes six, well developed, all subequal, ALE oval, PME squared, PLE oval; posterior eye row straight from above, procurved from front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide, pale orange, uniform, not fused to carapace, median concavity absent, with radial furrows between coxae I-II, II-III, III-IV, furrow smooth, radial furrow opposite coxae III absent, surface smooth, without pits, microsculpture absent, sickle-shaped structures absent, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins unmodified, without posterior hump; setae sparse, needle-like, evenly scattered, originating from surface. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae slightly divergent, anterior face unmodified; fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae needle-like, evenly scattered; paturon inner margin with pairs of enlarged setae, distal region unmodified, posterior surface unmodified, inner margin unmodified, laminate groove absent. Labium rectangular, anterior margin indented at middle, fusion of labium and sternum uncertain (moderately fused?); with 3-5 setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus unmodified, patella without prolateral row of ridges. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions yellow-reddish ground color, everywhere with narrow dark purple stripes and net-like pattern, cardiac mark pale, posteriorly with two posteriad pale lines. Book lung covers large, ovoid, without setae, anterolateral edge unmodified, connection of posterior spiracles by distal rim of postepigastric sclerite. Posterior spiracles not connected by groove. Pedicel tube short, ribbed, scuto-pedicel region unmodified, scutum not extending far dorsal of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent, cuticular outgrowths near pedicel absent. Dorsal scutum absent. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites present, without lateral joints. Postepigastric scutum weakly sclerotized, pale orange, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring, divided into 2 platelets. Dorsum setae present, needle-like. Epigastric area setae uniform, needle-like. Postepigastric area setae present, needle-like. Spinneret scutum without fringe of setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present, small plate with 2 setae. Spinnerets: ALS: not examined; PMS: not examined; PLS: not examined. LEGS: pale orange, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I near as long as carapace, tibia I unmodified, tibia IV specialized hairs on ventral apex absent, tibia IV ventral scopula absent, metatarsi I and II meso-apical comb absent , metatarsi III and IV weak ventral scopula absent, 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; v4-2-2; IV p1-1-0; v0-0-2; r1-1-0; metatarsi: I, II p1-0-0; v2-2-2; IV p1-1-0; r1-1-0. Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Ventral view: externally inconspicuous, anterior sclerite and plates somewhat visible through epigastric scutum. Dorsal view: internally with w-shaped large plate with distinct lateral extensions, medially trapezoidal protruding, wider than long, covering anterior genitalic process, anterior genitalic process protruding anteriorly, narrowly stalked with distinctly enlarged apex, broader than whole process length, originating from smaller plate (there are two small plates), cluster of filiform glands present at base of anterior genitalic process (whole process and plates are broken off at picture), posterior genitalic process (receptaculum) oval without remarkable duct, weakly sclerotized.
