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. Book lung covers small, very narrow, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube long, 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, pedicel tube ventrally ribbed. Scuto-pedicel region paired curved scutal ridges located close to the pedicel tube, in holotype distally slightly reduced. Dorsal scutum strongly sclerotized, orange-brown, without color pattern, covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum, anterior half without projecting denticles, surface very finely longitudinally striated giving the spider a matt appearance. Epigastric scutum strongly sclerotized, surrounding pedicel, slightly protuding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, orange-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, incomplete ring. Dorsum setae present, light, plumose. Epigastric area setae uniform, light, plumose. Postepigastric area setae present, light, plumose. Spinneret scutum with fringe of long setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present. LEGS: pale orange, without color pattern. Leg spines absent. GENITALIA: Epigastric region with sperm pore small, oval, situated at level of anterior spiracles, rebordered; furrow without omega-shaped insertions, without setae. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments pale orange; embolus dark, prolateral excavation absent, long, slender, lamellar embolus about as long as bulbus. Conductor about as long as embolus split into two parts half way to the distal tip. Embolus-conductor-complex bent proximally. Conical extension strongly pointed; trochanter normal size, with ventral projection; 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, without prolateral row of ridges, setae unmodified; tibia trichobothria with 3 trichobothria; cymbium pale orange, ovoid in dorsal view, fused with bulb but with clearly defined seam between, 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, stout, tapering apically.
