            Male (PBI_OON 49257). CEPHALOTHORAX: Carapace pale orange, 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, anterolateral corners without extension or projections, 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 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 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, 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 PME radius to PME diameter. Sternum longer than wide, yellow, 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, anterior corner unmodified, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins unmodified, without posterior hump, symmetrical elevations at anterior sternum rim present; setae abundant, needle-like, densest laterally, originating from surface, without hair tufts. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae straight, anterior face unmodified; fangs without tooth-like projections, directed medially, shape normal, without prominent basal process, tip unmodified; setae needle-like, evenly scattered, thick, distinctly anteriad directed; paturon inner margin with scattered setae, distal region unmodified, posterior surface unmodified, inner margin unmodified. Labium rectangular, fused to sternum, anterior margin indented at middle, same as sternum in sclerotization; with 6 or more setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, same as sternum in sclerotization, anterolateral rim distinctly stepped (in ventral view), most anterior part hyaline; posteromedially with distinct, short, horn-shaped, ventroposteriorly pointed projection. LEGS: yellow, 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 III and IV weak ventral scopula absent. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I d1-0-1; p0-0-1; II d1-0-1; III, IV d1-0-1; tibiae: III d1-0-0; p1-0-1; v0-1-2; r1-0-1; IV d1-0-1; p1-0-1; v0-1-2; r1-0-1; metatarsi: I, II v0-1-0; III d1-0-0; v0-1-2; r1-0-1; IV d1-0-1; p1-0-1; v0-1-2; r1-0-1. Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments pale orange; embolus dark, prolateral excavation absent, embolus tube shaped, moderately flattened, abruptly curved prolaterad, embolus opening large, skewed anteriad, posteriorly with distinctly long protruding tip; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella subbasally; patella about as long as femur, enlarged, without prolateral row of ridges, setae unmodified; tibia trichobothria not examined; cymbium pale orange, not fused with bulb, not extending beyond distal tip of bulb, plumose setae absent, without stout setae, without distal patch of setae, male palpal cymbium shape in dorsal view subrectangular, tarsal organ male palpal cymbium tarsal organ with 2 sensilla; cymbial cone present (moderately distant from the tarsal organ), close to distal cymbial rim; bulb pale orange, more than 2 times as long as cymbium, stout, spherical, distal part conductor broad, flat, long triangular, distally strongly narrowed, narrow leaf-shaped, protruding, originating prolaterally of embolus base, much shorter than embolus.
