Diagnosis. Characterized by the following features: wings reddish-brown, yellowish-brown or dark brown; forewing with M1 and R stalked, M stem clearly visible in discal cell; 2A of hindwing basally forked; tornus of hindwing usually with a prominent recurved tooth; uncus bifid; valvae hooked with apex produced into 2–3 teeth; shape and ornamentation of sternum VIII highly diagnostic. The sexual dimorphism is obvious, with the female larger and paler than the male..

Distribution. Oriental and SE Palaearctic Regions.

Remarks. Roepke (1924) illustrated the larva of G. proxima as having the thoracic segments strongly swollen as in Bombyx . Holloway (1987) reported that Mell described the early stages of G. engonata ( Swinhoe, 1899) in an unpublished manuscript. In this paper, three Gunda species are recorded from China (Map 12).
