CEPHALOTHORAX: Carapace orange-brown, 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, posterolateral surface without spikes, surface of elevated portion of pars cephalica smooth, sides granulate, thorax without depressions, fovea absent, sides of pars thoracica with obvious granulations reaching half way, without radiating rows of pits, sides of pars thoracica with obvious granulations reaching apex; lateral margin straight, rebordered, with blunt denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae dark, needle-like, present, scattered; non-marginal pars thoracica setae absent; marginal setae absent. Clypeus margin unmodified, straight 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, pLE and PME small, 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 separated by less than ALE radius, PME separated by less than their radius, PLE-PME separated by less than PME radius. Sternum longer than wide, orange-brown, uniform, 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 with continuous transverse groove, posterior margin not extending posteriorly of coxae IV, lateral margin without infra-coxal grooves, distance between coxae approximately equal, extensions of pre-coxal triangles absent, lateral margins unmodified, without posterior hump; setae abundant, dark, needle-like, evenly scattered, originating from surface. Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae straight, anterior face unmodified, elaborate macroseta on their inner face; 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 indented at middle; subdistal portion with unmodified setae. Endites distally excavated, anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus expanded, patella without prolateral row of ridges, palpal tarsus with black prolateral macrosetae basally and distal patch of setae. 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, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles not connected by groove. Pedicel tube medium, 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, scuto-pedicel region with small, curved scutal ridge just above pedicel. Dorsal scutum absent. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, without lateral joints. Postepigastric scutum strongly sclerotized, orange-brown, long, semicircular, covering nearly full length of abdominal length, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes, lateral sides of postepigastric scutum smooth. Spinneret scutum present, incomplete ring. Colulus represented only by setae. LEGS: pale orange, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I shorter than carapace, tibia IV specialized hairs on ventral apex absent, tibia IV ventral scopula absent, metatarsi III and IV weak ventral scopula absent.
