Clypeus margin slightly rebordered, curved downwards in front view, vertical in lateral view, median projection absent; setae present, light, needle-like. Chilum absent. Sternum about twice as long as wide, pale orange, uniform, fused to carapace, median concavity absent, without 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, extensions of pre-coxal triangles absent, lateral margins unmodified, without posterior hump, distance between coxae III and IV smaller than between coxae I and II and II and III. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae widely divergent, anterior face unmodified; without teeth on both promargin and retromargin; fangs without tooth-like projections, directed medially, shape normal, without prominent basal process, tip unmodified; setae light, needle-like, evenly scattered; paturon distal region unmodified, posterior surface unmodified, promargin unmodified, inner margin unmodified, laminate groove absent. Labium triangular, fused to sternum, anterior margin indented at middle, same as sternum in sclerotization; with 1 or 2 setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, serrula present in single row, anteromedian tip with one strong, tooth-like projection, posteromedian part unmodified, same as sternum in sclerotization. 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 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, scuto-pedicel region less than diameter of pedicel, paired scutal ridges short, not connected. Dorsal scutum weakly sclerotized, pale orange, without color pattern, covering full length 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, semicircular, covering nearly full length of abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum present, incomplete ring. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like. Spinneret scutum with fringe of stout setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane without setae. Colulus represented only by setae. LEGS: white, 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 I and II meso-apical comb absent, metatarsi III and IV weak ventral scopula absent. Leg spines absent. Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria not examined. GENITALIA: Epigastric region with sperm pore large, oval, situated at level of anterior spiracles, unmodified; furrow without omega-shaped insertions, without setae. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments yellow-brown; embolus light, prolateral excavation absent; trochanter normal size, unmodified; femur normal size, two or more times as long as trochanter, without posteriorly rounded lateral dilation, attaching to patella medially; patella longer than femur, much larger than femur, without prolateral row of ridges, setae unmodified, 0.234 long, 0.111 wide, connection to femur at 0.52.; tibia trichobothria not examined; cymbium pale orange, completely fused with bulb, no seam visible, not extending beyond distal tip of bulb, plumose setae absent, without stout setae, with distal patch of setae; bulb pale orange, 1 to 1.5 times as long as cymbium, slender, tapering apically, bulb ventrally slightly bulged completely fused to cymbium,..
