CEPHALOTHORAX: Carapace dark red-brown, without any pattern, ovoid in dorsal view, pars cephalica strongly elevated in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, with angular 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 striated, sides striated, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin straight, rebordered, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae dark, needle-like, present in u-shaped row; non-marginal pars thoracica setae dark, needle-like; marginal setae dark, needle-like. Clypeus margin unmodified, straight in front view, vertical in lateral view, low, ALE separated from edge of carapace by less than their radius, median projection absent; setae present, dark, needle-like. Chilum absent. Eyes six, well developed, ALE largest, ALE oval, PME circular, PLE circular; posterior eye row straight from both above and front; ALE separated by their radius to diameter, ALE-PLE separated by less than ALE radius, PME touching throughout most of their length, PLE-PME separated by less than PME radius. Sternum longer than wide, dark red-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 unmodified, 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 abundant, dark, needle-like, evenly scattered, originating from surface, without hair tufts. Mouthparts: Chelicerae, endites and labium dark red-brown. Chelicerae straight, anterior face unmodified; fangs without tooth-like projections, directed posteriorly, shape normal, without prominent basal process, tip unmodified; setae dark, needle-like, densest medially; paturon inner margin with pairs of enlarged setae, distal region unmodified, posterior surface unmodified, promargin unmodified, inner margin unmodified. Labium triangular, not fused to sternum, anterior margin not indented at middle, same as sternum in sclerotization; without 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 dark red-brown, without color pattern. Book lung covers large, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, with small, dorsolateral, triangular extensions, scuto-pedicel region with paired curved scutal ridges, 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 strongly sclerotized, dark red-brown, without color pattern, covering full length of abdomen, no soft tissue visible from above, fused to epigastric scutum, middle surface punctate, sides punctate, anterior half without projecting denticles. Epigastric scutum strongly sclerotized, not surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, dark red-brown, 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, complete ring. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like. Spinneret scutum with fringe of long setae. Dense patch of setae anterior to spinnerets present. Interscutal membrane with setae. Colulus absent. LEGS: red-brown, 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 I and II meso-apical comb absent, metatarsi III and IV weak ventral scopula absent. Leg spines absent. Trichobothria examined with Stereo microscope; tibia: each with three; metatarsus: each with one. GENITALIA: Epigastric region with sperm pore small, circular, situated at level of anterior spiracles, unmodified; furrow without omega-shaped insertions, without setae. Palp normal size, strongly sclerotized, right and left palps symmetrical, proximal segments red-brown; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella subbasally; patella longer than femur, enlarged, without prolateral row of ridges, setae unmodified; tibia trichobothria not examined; cymbium dark red-brown; bulb dark red-brown.
