CEPHALOTHORAX: Carapace pale orange, without any pattern, broadly oval in dorsal view, pars cephalica strongly 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, anterolateral corners without extension or projections, 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 light, needle-like, present, scattered; non-marginal pars thoracica setae absent; marginal setae absent. 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 absent. Chilum absent. Eyes six, well developed, all subequal, all eyes circular; 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 touching throughout most of their length, PLE-PME touching. Sternum as long as wide, pale orange, uniform, not 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 unmodified, posterior margin not extending posteriorly of coxae IV, anterior corner unmodified, distance between coxae approximately equal, extensions of pre-coxal triangles present, lateral margins with narrow extensions between coxae, without posterior hump; setae sparse, light, needle-like, evenly scattered, originating from surface, without hair tufts. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae straight, anterior face unmodified; without teeth on both promargin and retromargin; fangs without tooth-like projections, directed posteriorly, shape normal, without prominent basal process, tip unmodified; setae light, needle-like, evenly scattered; paturon inner margin with pairs of enlarged setae, distal region unmodified, posterior surface unmodified, promargin unmodified, inner margin unmodified. Labium not fused to sternum, same as sternum in sclerotization, wide, with a broad anterior indentation.; subdistal portion with unmodified setae, two subdistal normal 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 pale white, without color pattern. Book lung covers large, elliptical, without setae. Posterior spiracles not connected by groove. Pedicel tube short, unmodified, scuto-pedicel region unmodified, 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 weakly sclerotized, pale orange, without color pattern, covering 1/2 to 3/4 of abdomen, more than 1/2 to most of abdomen width, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles. Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum weakly sclerotized, pale orange, long, almost rectangular, covering about 1/2 of abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum absent. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like. Dense patch of setae anterior to spinnerets absent. Colulus represented only by setae. LEGS: white, 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. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): (leg I: femur: pv0-0-1-1-1-1; rv0-1-1 tibia: v2-2-2-2-2-0 metatarsus: v2-2-0, leg II: femur: pv0-0-0-1-1; rv1-1-1 tibia: v2-2-2-2-2-0 metatarsus: v2-2-0, leg III: tibia: v1ap metatarsus: v1ap. ).

GENITALIA: Epigastric region with sperm pore small, circular, situated at level of anterior spiracles, unmodified; furrow without omega-shaped insertions. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments white; embolus light, prolateral excavation absent, small, nearly straight; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella basally; patella shorter than femur, not enlarged, setae unmodified; tibia trichobothria not examined; cymbium white, completely fused with bulb, no seam visible, with distal patch of setae; bulb white, stout, tapering apically, with a ventral concavity.
