            Male (PBI_OON 26816). Total length 1.22. CEPHALOTHORAX: Carapace pale orange, without any pattern, ovoid in dorsal view, pars cephalica slightly 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, anterolateral corners without extension or projections, posterolateral surface without spikes, surface of elevated portion of pars cephalica smooth, sides granulate, thorax without depressions, fovea absent, granulate microsculpture not reaching elevated portion of pars cephalica, without radiating rows of pits; lateral margin straight; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae dark, needle-like, present, scattered; non-marginal pars thoracica setae dark, needle-like; marginal setae absent. Clypeus margin unmodified, curved downwards in front view, vertical in lateral view, high, ALE separated from edge of carapace by their radius or more, median projection absent; setae present, dark, needle-like. Chilum absent. Eyes six, well developed, ALE largest, ALE circular, PME squared, PLE oval; posterior eye row procurved from both above and front; ALE separated by less than their radius, 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, without radial furrows between coxae I-II, II-III, III-IV, radial furrow opposite coxae III absent, surface smooth, without pits, microsculpture absent, sickle-shaped structures absent, anterior margin with continuous transverse groove, posterior margin not extending posteriorly of coxae IV, anterior corner unmodified, lateral margin without infra-coxal grooves, distance between coxae approximately equal, extensions of pre-coxal triangles absent, lateral margins unmodified, without posterior hump; setae sparse, dark, needle-like, densest laterally, originating from surface, without hair tufts. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae slightly divergent, anterior face unmodified, paturon with anterolateral keel and one large plumose seta on anterior and posterior face at middle of fang base (seen under microscope); fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae dark, needle-like, evenly scattered; paturon inner margin with scattered setae, distal region unmodified. Labium triangular, fused to sternum, anterior margin not indented at middle, same as sternum in sclerotization; with 6 or more setae on anterior margin, subdistal portion with unmodified setae. Endites distally excavated, posteromedian part unmodified, same as sternum in sclerotization, anteriorly deeply depressed, with transversed ridge. Anteromedian part with a long spine-like anteriorly directed extension. ABDOMEN: cylindrical, 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, round, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, ribbed, 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, yellow, 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. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, yellow, long, semicircular, covering nearly full length of abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes, lateral side of postepigastric scutum finely striate. 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 represented only by setae. LEGS: yellow, 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 III and IV weak ventral scopula absent. Leg spines absent. Trichobothria examined with Compound microscope; tibia: each with three; metatarsus: each with one. GENITALIA: Epigastric region with sperm pore large, circular, situated at level of anterior spiracles; furrow without omega-shaped insertions, without setae. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments yellow; embolus dark, prolateral excavation absent; trochanter normal size, unmodified; femur enlarged, shorter than trochanter, without posteriorly rounded lateral dilation, attaching to patella basally; patella shorter than femur, not enlarged, without prolateral row of ridges, setae unmodified; tibia trichobothria with 3 trichobothria; cymbium yellow, ovoid in dorsal view, completely fused with bulb, no seam visible, 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, prolateral surface with stridulatory file.
