            Male (PBI_OON 32178). Total length 1.7. CEPHALOTHORAX: Carapace pale orange, without any pattern, ovoid 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 with 1 pair of spikes, surface of elevated portion of pars cephalica smooth, sides strongly reticulate, thorax without depressions, fovea absent, reticulation on carapace surface sides partly interrupted by smooth areas; sluice restricted to carapace posterior margin; carapace colour: 36 Amber (Smithe, 1975: Naturalist's Color Guide, AMNH), posterior margin of pars cephalica medially with a single "horn", 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 in u-shaped row, setae arranged in a long u-shaped row reaching posterior edge of pars cephalica; each setae originating from the middle of a pitlike structure with partly swollen edges; non-marginal pars thoracica setae absent; marginal setae light, needle-like, denticles at carapace margin represent modified hair bases; setae originating from anterior face of denticles, pointing anteriorly. Clypeus 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, a pair of long, needle-like setae on each half of the clypeus, with the inner ones longer and slightly thicker (thus appear slightly darker on stereomicroscope level) than the outer ones. Chilum absent. Eyes six, well developed, ALE largest, all eyes oval; posterior eye row recurved from above, procurved from front; ALE separated by their radius to diameter, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching. Sternum longer than wide, pale orange, uniform, fused to carapace, median concavity absent, with radial furrows between coxae I-II, II-III, III-IV, furrow wrinkled, radial furrow opposite coxae III absent, surface coarsely reticulate, without pits, microsculpture everywhere but middle, sickle-shaped structures absent, anterior margin with continuous transverse groove, posterior margin extending posteriorly beyond anterior edges of coxae IV as single extension, anterior corner unmodified, distance between coxae approximately equal, lateral margins unmodified, without posterior hump, radial furrows between coxae I-II, II-III and III-IV only very weakly developed, rather appearing as indentions of sternum margin; sternum microsculptures lobed; sternum surface setae originating from middle of microsculptures, smooth middle strip without setae; infra-coxal grooves present; setae sparse, light, needle-like, evenly scattered, originating from surface, without hair tufts. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae straight, proximal part of anterior face of paturon convex in lateral view; inner margin of paturon anterior face distally with small toohlike projection (outgrowth of paturon promargin), pointing inwards; without teeth on both promargin and retromargin; fangs without tooth-like projections, directed posteriorly, shape normal, without prominent basal process, tip unmodified; setae light, needle-like, evenly scattered, anterior face of cheliceraes with few, rather evenly scattered setae; paturon inner margin with scattered setae, distal region unmodified, promargin with row of flattened setae, inner margin unmodified. Labium triangular, fused to sternum, anterior margin deeply incised, same as sternum in sclerotization; subdistal portion with unmodified setae, ventral surface with 5 needle-like setae: two subdistal setae (one on each side of labium incision) and a transverse line of 3 more proximal setae. Endites distally not excavated, anteromedian tip unmodified, posteromedian part unmodified, same as sternum in sclerotization. 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, elliptical, without setae, anterolateral edge unmodified, booklung cover rather dumbbell- or pear-shaped, about 3x as long as wide (elongated elliptical, sides slightly concave), darker in colour than sourroundings (orange-brownish). Posterior spiracles connected by groove. Pedicel tube medium, ribbed, scuto-pedicel region with widely oval scutal ridge, scutum not extending far dorsal of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent. Dorsal scutum strongly sclerotized, pale orange, without color pattern, covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles, with rather long, darkish setae; surface smooth, bases of setae not "pit-like" thus scutum does not appear punctate as in other members of the genus. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, pale orange, long, semicircular, covering nearly full length of abdominal length, fused to epigastric scutum, anterior margin unmodified, with short posteriorly directed lateral apodemes. 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 needle-like setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Abdomen setae rather long and darkish. 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 ventral scopula absent, metatarsi I and II meso-apical comb absent , metatarsi III and IV weak ventral scopula absent, femora in dorsal view: Femur IV recurved, Femora I-II procurved, Femur III slightly procurved, tibiae see generic description in: MARCO THOMA, YVONNE KRANZ-BALTENSPERGER, CHRISTIAN KROPF, WERNER GRABER, WOLFGANG NENTWIG & HOLGER FRICK (2014): The new Southeast Asian goblin spider genus Aposphragisma (Araneae, Oonopidae): diversity and phylogeny. Zootaxa 3798 (1): 001086., metatarsi see generic description in: MARCO THOMA, YVONNE KRANZ-BALTENSPERGER, CHRISTIAN KROPF, WERNER GRABER, WOLFGANG NENTWIG & HOLGER FRICK (2014): The new Southeast Asian goblin spider genus Aposphragisma (Araneae, Oonopidae): diversity and phylogeny. Zootaxa 3798 (1): 001086.. Leg spines absent. Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria examined with Stereo microscope; tibia: each with three; metatarsus: each with one. GENITALIA: Epigastric region with sperm pore small, oval, situated at level of posterior spiracles, rebordered; furrow without omega-shaped insertions, without setae. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments pale orange; embolus dark, prolateral excavation absent; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella basally; patella shorter than femur, not enlarged, setae unmodified; cymbium yellow, ovoid in dorsal view, fused with bulb but with clearly defined seam between, not extending beyond distal tip of bulb, plumose setae absent, without stout setae, with distal patch of setae; bulb yellow, 1 to 1.5 times as long as cymbium, stout, tapering apically.
