Diptychophorini
Gaskin, 1971
Genus Guides
2Diptychophorini is a tribe of crambid within the Crambinae, established by Gaskin in 1971 and redefined based on morphological studies of male and female genitalia. The tribe includes the Glaucocharis, which is widely distributed across Australasia, Melanesia, and Polynesia. Diptychophorine moths are characterized by specific genitalic structures that distinguish them from other crambine tribes. The group has been subject to significant taxonomic revision, particularly regarding the priority of Glaucocharis over Pareromene.

Taxonomic History
The tribe Diptychophorini was established by Gaskin in 1971 and subsequently redefined in 1975 based on new morphological findings. The name has been widely used for the Pareromene since 1965, but priority rules require use of Glaucocharis. The tribe's definition relies heavily on genitalic , which serves as the basis for generic distinctions and group divisions.
