            Female (PBI_OON 10704). Total length 2.56. CEPHALOTHORAX: Carapace red-brown, without any pattern, broadly oval in dorsal view, pars cephalica strongly 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, sides granulate, thorax without depressions, fovea absent, elevated portion of pars cephalica with low tubercles around midline, surrounded by U-shaped smooth area, without radiating rows of pits; lateral margin straight, rebordered, with sharply pointed 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 present; setae present, light, needle-like. Chilum undivided, fused to clypeus, seam present, small triangle, extending only slight distance. Eyes six, well developed, ALE largest, ALE oval, PME squared, PLE oval; posterior eye row recurved from above, procurved from front; ALE separated by less than their radius, 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, without radial furrows between coxae I-II, II-III, III-IV, radial furrow opposite coxae III absent, without pits, microsculpture everywhere but front, 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, surface crenulated, depressions separated by anastomosing ridges; setae sparse, light, needle-like, densest laterally, originating from surface. Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae slightly divergent, anterior face with swelling, anterior face of paturon with small, rounded ledge; 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 unmodified, 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; 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 not connected by groove. Pedicel tube medium, 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 absent. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum strongly sclerotized, pale orange, almost semicircular, covering about 1/3 of the abdominal length, fused to epigastric scutum, anterior margin unmodified, with short 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. Dense patch of setae anterior to spinnerets absent. Colulus present, tiny, with pair of setae. Spinnerets: ALS: bisegmented; PMS: unisegmented; PLS: bisegmented. LEGS: orange-brown, 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. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I p0-0-2; r0-1-2; II p0-0-2; r0-1-0; 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: Shape: gentalic atrium large, unsclerotized, ovoid, almost as long as postepigastric scutum.
