Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, pale orange, long, semicircular, covering about 3/4 of abdominal length, fused to epigastric scutum, anterior margin unmodified, with short posteriorly directed lateral apodemes. Spinneret scutum absent. Dorsum setae present, needle-like. Epigastric area setae uniform, needle-like. Postepigastric area setae present, needle-like. Spinneret scutum without fringe of setae. Dense patch of setae anterior to spinnerets absent. Interscutal membrane with setae. Colulus present, colulus with a single, posteriorly directed setae..
