Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, orange-brown, almost semicircular, covering about 3/4 of abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum absent. Dorsum setae present, needle-like. Epigastric area setae uniform, needle-like. Postepigastric area setae present, needle-like. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus represented only by setae. LEGS: orange-brown, 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 present, tibia IV ventral scopula absent, metatarsi I and II meso-apical comb absent, metatarsi III and IV weak ventral scopula absent. GENITALIA: Epigastric region with sperm pore small, triangular with rounded angles, situated at level of anterior spiracles, unmodified; furrow without omega-shaped insertions, without setae. Palp normal size, not strongly sclerotized, right and left palps symmetrical, proximal segments pale orange; embolus dark, embolus long slender, sinuous; conductor-like sclerite as long as embolus, piriform, semi-translucid, with distal filiform short processes; trochanter normal size, unmodified; 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 tibia slightly rounded; cymbium pale orange, narrow in dorsal view, completely fused with bulb, no seam visible, plumose setae absent, without stout setae, without distal patch of setae; bulb pale orange, slender, elongated.
