            Female (PBI_OON 2495). Total length 1.86. CEPHALOTHORAX: Carapace pale orange, without any pattern, broadly oval in dorsal view, pars cephalica strongly 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 smooth, sides finely reticulate, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin straight, rebordered, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae dark, needle-like, present in u-shaped row; non-marginal pars thoracica setae dark, needle-like; marginal setae dark, 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, dark, needle-like. Chilum absent. Eyes six, well developed, ALE largest, ALE oval, PME squared, PLE oval; posterior eye row recurved 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 extending posteriorly beyond anterior edges of coxae IV as single extension, lateral margin with infra-coxal grooves and anterior and posterior openings, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins with narrow extensions between coxae, without posterior hump; setae sparse, dark, needle-like, densest laterally, originating from surface. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae straight, anterior face unmodified; promargin with one tooth, retromargin without teeth; fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae dark, needle-like, densest medially; paturon inner margin with scattered setae, distal region unmodified, posterior surface unmodified, promargin with row of flattened setae, inner margin unmodified, laminate groove absent. Labium triangular, not fused to sternum, anterior margin not indented at middle; with 1 or 2 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, patella without prolateral row of ridges. ABDOMEN: cylindrical, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions white, without color pattern. Book lung covers large, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles not connected by groove. Pedicel tube short, unmodified, scuto-pedicel region unmodified, scutum 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 strongly sclerotized, pale orange, without color pattern, covering 1/2 to 3/4 of abdomen, more than 1/2 to most of abdomen width, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum weakly sclerotized, pale orange, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, with short posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like. Spinneret scutum with fringe of stout setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present. LEGS: pale orange, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I shorter than 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, patellae patella I elongate, measured dorsally, almost as long as tibia, other patellae elongated but less dramatically so. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): patellae: I v1p-1r-1r; tibiae: I v1p-2-2; II v1r-1r-0; IV v0-0-2. Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Shape: ovoid atrium present between medially invagined edges of epigastric and postepigastric scuta, that atrium with transverse sclerotization. Dorsal view: anterior receptaculum short, distally rounded, posterior receptacuum long, with tiny distal squiggle.
