            Female (PBI_OON 3481). CEPHALOTHORAX: Carapace yellow, without any pattern, ovoid in dorsal view, pars cephalica slightly elevated in lateral view, anteriorly narrowed to between 0.5 and 0.75 times its maximum width, with rounded posterolateral corners, posterolateral edge without pits, posterolateral surface without spikes, surface of elevated portion of pars cephalica smooth, thorax without depressions, carapace anteriorly narrowed to 0.5 times its maximum width. Lateral surfaces with very shallow microsculpture, without radiating rows of pits; lateral margin straight, rebordered; non-marginal pars cephalica setae short setae on carapace. Clypeus curved downwards in front view, high, ALE separated from edge of carapace by their radius or more, median projection absent, aLE separated from edge of carapace by their diameter; setae present. Eyes six, eyes small. PME touching or almost touching, PLE well-separated from PME, ALE less than one diameter apart, ALE largest, ALE oval, PME oval. Sternum longer than wide, yellow, uniform, fused to carapace, median concavity absent, surface smooth, without pits, sickle-shaped structures absent, anterior margin unmodified, posterior margin extending posteriorly, ending in two short sclerotized prongs, distance between coxae approximately equal, without posterior hump, no clearly defined radial furrows; setae abundant, needle-like, evenly scattered. Mouthparts: Chelicerae, endites and labium yellow. Chelicerae anterior face unmodified; fangs shape normal, without prominent basal process, tip unmodified; setae sparse setae on anterior surface of paturon. Labium not fused to sternum; with setae. Endites anteromedian tip unmodified, posteromedian part unmodified. Female palp spines absent; tarsus unmodified, patella without prolateral row of ridges, segments yellow. Femur twice as long as patella, patella and tibia subequal, tarsus about twice as long as tibia. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly, elongated ovoid; dorsum soft portions white, without color pattern. Book lung covers ovoid, anterolateral edge unmodified, medium-sized. Not covered with white, matted setae. Pedicel tube short, unmodified, scuto-pedicel region unmodified, matted setae on anterior ventral abdomen in pedicel area absent. Dorsal scutum strongly sclerotized, yellow, without color pattern, covering less than 1/2 of abdomen, not fused to epigastric scutum, middle surface smooth, sides smooth, anterior half without projecting denticles, dS small, covering only 1/3 of abdomen length. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, yellow. Postepigastric scutum strongly sclerotized, yellow, not fused to epigastric scutum, pES short, leaving more than half of ventral abdomen uncovered, rounded posteriorly. Lateral apodemes rather short. Spinneret scutum present, incomplete ring, spinneret scutum a narrow, incomplete ring with fringe of needle-like setae. Anal scutum present, weakly sclerotized. Spinneret scutum with fringe of needle-like setae. Dense patch of setae anterior to spinnerets absent. Colulus present, colulus small, sporting two setae. LEGS: yellow, without color pattern; femur IV not thickened, same size as femora I-III, patella plus tibia I shorter than carapace. Leg spines absent. Tarsi I to IV superior claws tooth not examined in detail. Trichobothria examined with Stereo microscope; tibia: each with three; metatarsus: each with one; each leg with four dorsal trichobothria: one on proximal tibia, two on distal tibia, one on distal metatarsus. GENITALIA: Ventral view: anterior margin of PES appears to form a scape-like structure that extends almost the entire length of the PES. A red-brown stripe extending along length of scape..
