Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent, posterior border sinuous. Postepigastric scutum strongly sclerotized, orange-brown, almost semicircular, covering about 2/3 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: pale orange, 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.
