            Female (PBI_OON 671). Total length 2.49. CEPHALOTHORAX: Carapace dark red-brown, without any pattern, ovoid 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 strongly reticulate, sides granulate, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin straight, rebordered, with blunt denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae light, needle-like, present, scattered; non-marginal pars thoracica setae light, needle-like; marginal setae light, needle-like. Clypeus margin strongly rebordered, sinuous in front view, vertical in lateral view, high, ALE separated from edge of carapace by their radius or more, median projection absent; setae present, light, needle-like. Chilum undivided, small, triangular, fused to clypeus, seam present. 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 wider than long, orange-brown, 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, sickle-shaped structures absent, anterior margin with continuous transverse groove, 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 absent, lateral margins with bridges to coxae, without posterior hump, with three transverse ridges connected by longitudinal ridge along midline; tubercles present at sides of smooth areas between ridges and at posterior margin; setae sparse, light, needle-like, densest laterally, originating from surface. Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae slightly divergent, anterior face with swelling; with one tooth on both promargin and retromargin; fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae light, needle-like, densest medially; paturon inner margin with pairs of enlarged setae, distal region abruptly narrowed, posterior surface unmodified, promargin with row of flattened setae, inner margin unmodified, laminate groove absent. Labium triangular, not fused to sternum, anterior margin indented at middle, posterior portion flattened, anterior part at sharp angle; with 6 or more 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: ovoid, 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 connected by groove. Pedicel tube long, ribbed, 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, orange-brown, without color pattern, covering more than 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 strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum strongly sclerotized, orange-brown, long, semicircular, covering about 3/4 of abdominal length, fused to epigastric scutum, anterior margin unmodified, with short posteriorly directed lateral apodemes, groove connecting posterior spiracles continued almost to lateral margins. Spinneret scutum present, incomplete ring. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like. Spinneret scutum with fringe of long setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present. LEGS: yellow-brown; 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, femora i-IV darkened. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I, II p0-0-2; r0-2-1; tibiae: I v4-4-2; II v4-4-1p; metatarsi: I v2-2-1p; II v2-1p-2. Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Ventral view: atrium oval, mostly filled by rectangular sclerotization including darkened, U-shaped base of anterior genitalic process.
