CEPHALOTHORAX: Carapace yellow, without any pattern, pyriform in dorsal view, pars cephalica flat 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, anterolateral corners without extension or projections, posterolateral surface without spikes, thorax without depressions, fovea absent, carapace color: pale yellow. Microsculpture faintly visible on sides of carapace., without radiating rows of pits; lateral margin straight, rebordered; non-marginal pars cephalica setae dark. Clypeus curved downwards in front view, median projection absent. Eyes absent. Sternum as long as wide, white, uniform, fused to carapace, median concavity absent, with radial furrows between coxae I-II, II-III, III-IV, furrow smooth, surface smooth, microsculpture absent, sickle-shaped structures absent, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV, anterior corner unmodified, without posterior hump, pre-coxal triangles may be present but very faint.; setae sparse, dark, without hair tufts. Mouthparts: Chelicerae, endites and labium yellow. Chelicerae slightly divergent, anterior face unmodified; fangs shape normal, without prominent basal process, tip unmodified. Labium not fused to sternum, anterior margin indented at middle, same as sternum in sclerotization, indentation at middle of anterior margin rather pronounced.. Endites posteromedian part unmodified, same as sternum in sclerotization, anteriormost part of endites appearing pointed and slightly more sclerotized.. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly, shape: elongated ovoid.. Book lung covers large, ovoid, anterolateral edge unmodified. Pedicel tube short, unmodified, scuto-pedicel region unmodified, scutum extending far dorsal of pedicel, matted setae on anterior ventral abdomen in pedicel area absent. Dorsal scutum strongly sclerotized, yellow, without color pattern, covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum, anterior half without projecting denticles. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, color: yellow.. Postepigastric scutum strongly sclerotized, yellow, covering nearly full length of abdominal length, fused to epigastric scutum. Spinneret scutum present, incomplete ring. Interscutal membrane with setae. LEGS: white; patellae patella almost as long as tibia, tibiae patella plus tibia II length: shorter than carapace. Tibia about as long as metatarsus; on lateral surfaces of tibia a few small, more or less oval glands with minute central pore, metatarsi on ventral surface of metatarsus II two setae that are flatter than other leg setae.

Retrolateral element tube-shaped except for tip which is flattened; may be embolus but sperm duct opening could not be localized. Outer edge of retrolateral element forming ridge. Prolateral element broad, distally splitting in three flaps, a retrolateral flap and a dorsal and ventral prolateral flap; ventral prolateral flap somewhat thread-like, others flat. Ventral surface of bulb with small indentation near base of appendage..

            Female (PBI_OON 9842). Total length 1.04. As in male except as noted. CEPHALOTHORAX: Carapace white, anteriorly narrowed to 0.49 times its maximum width or less, on sides of carapace microsculpture faintly visible; best visible on lower part of carapace.; non-marginal pars thoracica setae dark. Clypeus setae present, dark. Chilum undivided, chilum small and brown, more or less triangular in shape.. Sternum without pits, sternum slightly longer than wide. Pre-coxal triangles possibly present but too faint to ascertain.; setae abundant. Mouthparts: Chelicerae, endites and labium white. setae dark. Labium indentation at middle of anterior margin rather pronounced.; three setae visible on subdistal labium.. Endites anteromedian tip unmodified. Female palp spines absent; tarsus unmodified, palpal tibia not much longer than palpal patella.. ABDOMEN: dorsum soft portions white, without color pattern. Book lung covers round. Dorsal scutum covering more than 3/4 of abdomen, more than 1/2 to most of abdomen width. Epigastric scutum color: yellow.. Postepigastric scutum short, almost rectangular, covering about 2/3 of abdominal length, not fused to epigastric scutum, anterior margin unmodified. Supra-anal scutum absent. Spinneret scutum with fringe of needle-like setae. Dense patch of setae anterior to spinnerets absent. LEGS: patella plus tibia I shorter than carapace. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): tibiae: I v2-2-2; II v0-2-2; metatarsi: I, II v0-2-2; (leg I: spines short, leg II: spines short. ). Tarsi I to IV superior claws tooth not examined in detail. Trichobothria examined with Stereo microscope; tibia: I three; metatarsus: I one; single trichobothrium on metatarsus I & II situated distally. On tibia I & II one trichobothrium situated approximately medially and two situated distally; latter two opposing each other. Probably a similar situation on leg III & IV but not every trichobothrium could be confirmed (several trichobothria lying too close to leg surface).. GENITALIA: Ventral view: external genitalia lacking. Anterior margin of PES thickened medially; immediately behind thickened margin a very small internal structure visible through PES.
