Clypeus margin strongly rebordered, 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, light, needle-like, margin of clypeus with few longer setae, directed anteriorly. Chilum absent. Eyes six, well developed, ALE largest, ALE circular, PME oval, PLE oval; posterior eye row procurved from both above and front; ALE touching, ALE-PLE touching, PME touching throughout most of their length, PLE-PME touching. Sternum longer than wide, yellow, 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 II and III greater than distance between coxae I and II, and coxae III and IV, extensions of pre-coxal triangles present, lateral margins unmodified, without posterior hump, slightly more setae on anterior margin of sternum; setae abundant, light, needle-like, evenly scattered, originating from surface, without hair tufts. Mouthparts: Chelicerae, endites and labium pale orange. Chelicerae slightly divergent, anterior face unmodified; 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 scattered setae, distal region unmodified.

Endites distally not excavated, anteromedian tip with one strong, tooth-like projection, posteromedian part unmodified, same as sternum in sclerotization, posteromedian part slightly more sclerotized. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions white, without color pattern.

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. Dorsal scutum weakly sclerotized, pale orange, without color pattern, covering about 1/2 of abdomen, more than 1/2 to most of abdomen width, 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, anterior margin of sperm pore with a fringe of needle-like setae. Postepigastric scutum weakly sclerotized, pale orange, short, almost rectangular, covering about 2/3 of abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum absent, very pale, details not clearly visible. Dorsum setae present, light, needle-like, few longer setae on anterior margin of dorsal scutum. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like. Spinneret scutum with fringe of long setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus absent. 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, tibiae tibia of leg III and IV with one spine-like hair on the prolateral apex. Tibia of leg III and IV with harpoon-like hairs, metatarsi metatarsi of leg III and IV with harpoon-like hairs. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): femora: I, II p0-0-2; r0-0-1; tibiae: I, II p2-1-1; r2-1-1; metatarsi: I, II p1-1-0; r1-1-0; (leg I: retrolateral spine on femur small, leg II: retrolateral spine on femur small. ). Tarsi I to IV superior claws tooth not examined in detail. Tarsi I to IV without inferior claw. Trichobothria examined with Compound 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 brown; embolus not discernible; trochanter normal size, unmodified; femur normal size, one to two times as long as trochanter, attaching to patella basally; patella about as long as femur, not enlarged; tibia trichobothria with 3 trichobothria; cymbium brown, ovoid in dorsal view, fused with bulb but with clearly defined seam between, not extending beyond distal tip of bulb, without distal patch of setae; bulb brown, more than 2 times as long as cymbium, stout, tapering apically, middle part with double ventral protuberance, one slightly elongated, distal part paler than rest of palp, laterally extending and bending at its tip.
