Epigastric scutum weakly sclerotized, surrounding pedicel, slightly protuding, small lateral sclerites absent. Postepigastric scutum weakly sclerotized, pale orange, long, almost rectangular, covering about 3/4 of abdominal length, fused to epigastric scutum, anterior margin unmodified, with long posteriorly directed lateral apodemes. Spinneret scutum absent. Supra-anal scutum absent. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like.
