CEPHALOTHORAX: Carapace pale orange, without any pattern, broadly oval 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, posterolateral surface without spikes, surface of elevated portion of pars cephalica finely reticulate, sides finely reticulate, thorax without depressions, fovea absent, without radiating rows of pits; lateral margin undulate, rebordered, without denticles; plumose setae near posterior margin of pars thoracica absent; non-marginal pars cephalica setae needle-like, present, scattered; non-marginal pars thoracica setae needle-like; marginal setae needle-like. Clypeus margin slightly rebordered, 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, needle-like. Chilum absent. Eyes six, well developed, all subequal, all eyes oval; posterior eye row procurved 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 PME radius to PME diameter. Sternum longer than wide, yellow, uniform, not 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, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins unmodified, without posterior hump; setae sparse, needle-like, evenly scattered, originating from surface. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae slightly divergent, anterior face unmodified; fangs directed medially, shape normal, without prominent basal process, tip unmodified; setae needle-like, evenly scattered; paturon inner margin with pairs of enlarged setae, distal region unmodified, posterior surface unmodified, inner margin unmodified, laminate groove absent. Labium rectangular, fused to sternum, anterior margin indented at middle; with 3-5 setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, anteromedian tip unmodified, posteromedian part unmodified. Female palp claws absent; spines absent; tarsus unmodified, patella without prolateral row of ridges. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions yellow-reddish ground color, anterolaterally with indistinct narrow stripes, other parts with dark purple spots and fine-mashed net-like pattern, cardiac mark pale, posteriorly with two posteriad pale lines. Book lung covers large, ovoid, without setae, anterolateral edge unmodified, connection of posterior spiracles by distal rim of postepigastric sclerite. Posterior spiracles not connected by groove. Pedicel tube short, ribbed, 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 absent. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites present, without lateral joints. Postepigastric scutum weakly sclerotized, yellow, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring, divided into 2 platelets. Dorsum setae present, needle-like. Epigastric area setae uniform, needle-like. Postepigastric area setae present, needle-like. Spinneret scutum without fringe of setae. Dense patch of setae anterior to spinnerets absent. Colulus present, small plate with 2 setae. Spinnerets: ALS: not examined; PMS: not examined; PLS: not examined. LEGS: yellow, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I near as long as 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, tibiae emerit's glands not examined, tarsi pairs of special setae with distinct flattened clawlike apexes present on tarsi III, IV.

Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Ventral view: externally inconspicuous, anterior sclerite and plates somewhat visible through epigastric scutum. Dorsal view: internally with large w-shaped plate with short lateral extensions, medially protruding, moderately wider than long, covering anterior genitalic process, anterior genitalic process protruding anteriorly, narrowly stalked with distinctly suboval enlarged apex, originating from smaller plate (there are two small plates), cluster of few long filiform glands present at base of anterior genitalic process, posterior genitalic process (receptaculum) suboval pocketlike without remarkable duct, anteriorly covered by plate.
