Labium elongated hexagon, not fused to sternum, anterior margin indented at middle, same as sternum in sclerotization; with 3-5 setae on anterior margin, subdistal portion with unmodified setae. Endites distally not excavated, serrula present in single row, anteromedian tip unmodified, posteromedian part unmodified, same as sternum in sclerotization, with a lateral furrow that bisects the maxilla in two sections: a dorsal one, flattened, bearing the serrula, and a ventral one, thickened, with a truncated, less sclerotized tip. ABDOMEN: ovoid, without long posterior extension, rounded posteriorly, inter-scutal membrane rows of small sclerotized platelets absent posteriorly; dorsum soft portions pale white, without color pattern.

Postepigastric scutum weakly sclerotized, short, only around epigastric furrow, not fused to epigastric scutum, anterior margin unmodified, without posteriorly directed lateral apodemes. Spinneret scutum absent. Dorsum setae present, light, needle-like. Epigastric area setae uniform, light, needle-like. Postepigastric area setae present, light, needle-like.
