Mouthparts: Chelicerae, endites and labium orange-brown. Chelicerae slightly divergent, anterior face unmodified, very few setae on paturon inner margin and mainly at distal area; fangs without tooth-like projections, directed medially, shape normal, without prominent basal process, tip unmodified; setae needle-like, densest medially; paturon inner margin with brush of short thorn-like seta, distal region unmodified. Labium triangular, not fused to sternum, same as sternum in sclerotization; with 1 or 2 setae on anterior margin. Endites distally not excavated, anteromedian tip with one strong, tooth-like projection, posteromedian part unmodified, much more heavily sclerotized than sternum. 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, booklung covers slightly domed. Posterior spiracles connected by groove. Pedicel tube short, ribbed, scuto-pedicel region with W-shaped scutal ridge, 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 strongly sclerotized, orange-brown, without color pattern, covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum, middle surface punctate, sides punctate, anterior half without projecting denticles, . Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, orange-brown, almost 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. Supra-anal scutum absent. Dorsum setae present, needle-like. Epigastric area setae uniform, needle-like. Postepigastric area setae present, needle-like. Spinneret scutum with fringe of needle-like setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. 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 present, tibia IV ventral scopula absent, metatarsi III and IV weak ventral scopula absent. Leg spination (only surfaces bearing spines listed, all spines longer than segment width): (leg I: setae on ventral surface of tibia and metatarsus leg I reamarkably stroger. However characterization as "spines" is dubiuous. ). Tarsi I to IV superior claws tooth not examined in detail. GENITALIA: Epigastric region with sperm pore small, oval, situated at level of anterior spiracles, rebordered; furrow without omega-shaped insertions, without setae. Palp minute, strongly sclerotized, right and left palps symmetrical; embolus dark; trochanter normal size, with ventral projection; femur normal size, one to two 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 dark red-brown, narrow in dorsal view, completely fused with bulb, no seam visible, covered with plumose setae, without stout setae, without distal patch of setae; bulb dark red-brown, more than 2 times as long as cymbium, slender, elongated.
