Labium triangular, fused to sternum, anterior margin indented at middle, same as sternum in sclerotization; subdistal portion with unmodified setae. Endites distally excavated, serrula absent, anteromedian tip unmodified, posteromedian part unmodified, same as sternum in sclerotization. ABDOMEN: cylindrical, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions white, without color pattern.

Dorsal scutum strongly sclerotized, pale orange, without color pattern, covering full length of abdomen, no soft tissue visible from above, not fused to epigastric scutum, middle surface punctate, sides punctate, anterior half without projecting denticles, with shallow pits. Epigastric scutum strongly sclerotized, surrounding pedicel, not protruding, small lateral sclerites absent. Postepigastric scutum strongly sclerotized, pale orange, long, semicircular, covering nearly full length 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.
