Autapomorphy of Cincticostella/g3.

(1) In larva lateral projection at anterior part of mesonotum [see Cincticostella/g1 (2)] is flat; lateral margin of this projection anteriorly arises from anterior-lateral angle of mesonotum, posteriorly it passes dorsad of lateral margin of mesonotum and terminates by a ledge; pronotum is wide, its posterior margin has the same width as anterior margin of mesonotum together with its lateral projections (Allen 1971: Fig.16–18; Kluge 2004: Fig.92:A). Unique apomorphy.

Size. Fore wing length 6–14 mm.

Distribution. Eastern Asia.
