Endites distally not excavated, serrula present in single row, anteromedian tip with one strong, tooth-like projection, posteromedian part unmodified, same as sternum in sclerotization. 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. Book lung covers large, ovoid, without setae, anterolateral edge unmodified. Posterior spiracles not connected by groove. Pedicel tube medium, with fringe of setae, scuto-pedicel region unmodified, scutum absent, but abdomen extending anteriad of pedicel, plumose hairs absent, matted setae on anterior ventral abdomen in pedicel area absent, cuticular outgrowths near pedicel absent.
