Epigastric scutum weakly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum weakly sclerotized, pale orange, short, almost rectangular, covering about 2/3 of abdominal length, fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum present, incomplete 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 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.
