            Female (PBI_OON 30838). Total length 2.12. CEPHALOTHORAX: Carapace yellow, without any pattern, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width, 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 smooth, sides smooth, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin straight, smooth, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae dark, needle-like, present, scattered; non-marginal pars thoracica setae dark, needle-like; marginal setae dark, needle-like. Clypeus margin unmodified, curved downwards in front view, vertical in lateral view, low, ALE separated from edge of carapace by less than their radius, median projection absent; setae present, dark, needle-like. Chilum absent. Eyes six, well developed, all subequal, all eyes circular; posterior eye row recurved from above, straight 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, yellowish white, uniform, not fused to carapace, median concavity absent, without radial furrows between coxae I-II, II-III, III-IV, 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, lateral margin without infra-coxal grooves, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins unmodified, without posterior hump; setae sparse, dark, needle-like, evenly scattered, originating from surface. Mouthparts: Chelicerae, endites and labium yellow. Chelicerae straight, anterior face unmodified; without teeth on both promargin and retromargin; fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae dark, needle-like, evenly scattered; paturon inner margin with pairs of enlarged setae, distal region unmodified, posterior surface unmodified, promargin unmodified, inner margin unmodified, laminate groove absent. Labium elongated hexagon, not fused to sternum, anterior margin indented at middle; with 3-5 setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, serrula present in single row, anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus unmodified. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions pale white, without color pattern. Book lung covers large, elliptical, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, unmodified, 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, not surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum weakly sclerotized, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum absent. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like. Spinneret scutum without fringe of setae. Dense patch of setae anterior to spinnerets absent. Colulus represented only by setae. LEGS: yellow, without color pattern; 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, femora femora IV slightly thickener tha femora I-III. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): (leg I: femora: d1;, leg II: femora: d1-0-1, tibiae: d1;, leg III: femora: d0-1-0-1-1, tibiae: d1-0, p1-0, v1subap, r1-1, metatarsi: d1-0-1, p1-0-1, v1-1-2ap, r1-1;, leg IV: femora: d0-1-10-1-1, tibiae: d1-0, p1-1, r1-1, metatarsi: d1-0-1, p1-0-1-1ap, v0-1-1-2ap, r1-1. ). Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Dorsal view: anterior receptacle with two elements, a ventral, solid, T-shaped that serves as muscla attachment, and other dorsal, with thickened walls and gland tissue; with a narrow anterior projection (with a dorsal, sac-like, membranous vesicle)and a basal, globular part. Two short, narrow, transverse ridges connected between them above the base of the anterior receptacle, have perpendicular projections at the sides, flanking laterally the globular part of the AR. The transverse bars donīt reach to the lateral apodemas of the posterior, procurved bar. Posterior receptacle medium sized, wider than long, traslucent..
