CEPHALOTHORAX: Carapace pale orange, without any pattern, pyriform in dorsal view, pars cephalica flat 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, 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 straight, smooth, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae absent, sparse small pits visible, setae probably lost.; non-marginal pars thoracica setae absent, sparse small pits visible, setae probably lost.; marginal setae absent. Clypeus margin unmodified, straight in front view, vertical in lateral view, median projection absent; setae absent. Chilum absent. Eyes absent, no eye remnants visible. Sternum longer than wide, pale orange, uniform, not fused to carapace, median concavity absent, without radial furrows between coxae I-II, II-III, III-IV, surface smooth, without pits, microsculpture absent, sickle-shaped structures absent, anterior margin unmodified, posterior margin not extending posteriorly of coxae IV, lateral margin without infra-coxal grooves, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins unmodified, without posterior hump; setae sparse, light, needle-like, densest laterally, originating from surface. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae straight, anterior face unmodified; without teeth on both promargin and retromargin; fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae dark, needle-like, evenly scattered; paturon inner margin with pairs of enlarged setae, distal region abruptly narrowed, posterior surface unmodified, promargin unmodified, inner margin unmodified. Labium triangular, not fused to sternum, anterior margin indented at middle, the incision of the labium is less deep than in the other species; with 1 or 2 setae on anterior margin, subdistal portion with unmodified setae. Endites distally excavated, serrula present in single row, anteromedian tip unmodified, posteromedian part unmodified, relatively long, parallel, slightly dilated distally. Female palp claws absent; spines absent; tarsus unmodified; trichobothria tibia with at least one prodorsal trichobothrium in proximal half.. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions pale white, without color pattern. Book lung covers large, elliptical, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, unmodified, scuto-pedicel region unmodified, scutum not 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 weakly sclerotized, yellow-brown, without color pattern, covering less than 1/2 of abdomen, less than 1/4 abdomen width, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles, scutum a pale and very narrow strip anteriorly in the middle over one third of abdomen length. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum weakly sclerotized, yellow-brown, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like. Spinneret scutum without fringe of setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus colulus and spinnerets sunk, barely visible..
