Chelicerae straight, anterior face unmodified; fangs directed posteriorly, shape normal, without prominent basal process, tip unmodified; setae dark, needle-like, densest medially; paturon inner margin with pairs of enlarged setae, distal region unmodified, posterior surface unmodified, promargin unmodified, inner margin unmodified. Labium triangular, not fused to sternum, anterior margin not indented at middle; without setae. Endites distally not excavated, anteromedian tip unmodified, posteromedian part unmodified. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions yellow-brown, without color pattern. Book lung covers large, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles connected by groove. Pedicel tube short, 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, cuticular outgrowths near pedicel absent. Dorsal scutum strongly sclerotized, yellow-brown, without color pattern, covering full length of abdomen, no soft tissue visible from above, fused to epigastric scutum, middle surface punctate, sides punctate, anterior half without projecting denticles. Epigastric scutum strongly sclerotized, not surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, yellow-brown, long, semicircular, covering nearly full length of abdominal length, anterior margin unmodified, with short posteriorly directed lateral apodemes. Spinneret scutum present, complete ring. Dorsum setae present, dark, needle-like. Epigastric area setae uniform, dark, needle-like. Postepigastric area setae present, dark, needle-like. Spinneret scutum with fringe of long setae. Dense patch of setae anterior to spinnerets present. Interscutal membrane with setae. Colulus absent. LEGS: yellow, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I shorter than 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 spines absent. Trichobothria examined with Stereo microscope; tibia: each with three; metatarsus: each with one.
