Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, orange-brown, long, semicircular, covering nearly full length of abdominal length, fused to epigastric scutum, anterior margin unmodified, with long posteriorly directed lateral apodemes, with longitudinal elevated ridge covered with a line of slim plumose setae between lateral apodemes. Spinneret scutum present, incomplete ring. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like.
