Glaucocharis Meyrick, 1938

Glaucocharis Meyrick, 1938: 426 . Type species: Glaucocharis stella Meyrick, 1938 . Ditomoptera Hampson, 1893: 179 . Type species: Ditomoptera minutalis Hampson, 1893 . Pareromene Osthelder, 1941: 366 . Type species: Pareromene rebeli Osthelder, 1941 . Pagmania Amsel, 1961: 332 . Type species: Pagmania bilinealis Amsel, 1961 .

General characters. Forewing with conspicuous antemedian and postmedian lines, reniform stigma present or absent, apex usually with an apical mark, termen below apex with an indentation reaching tip of M1, and sometimes with a secondary indentation at tip of M3, marginal spots developed; Sc and R1 stalked, R2 free, R3 and R4 stalked, M2 and M3 separated; hindwing with open cell, M2 and M3 separated. Male genitalia with long and thin or broad and short uncus; gnathos usually long and thin, varied in shape; valva long and narrow, mostly symmetrical; costa usually well-sclerotized, basal prong present or absent; juxta varied in shape, accessory structure present or absent; phallus with or without apical spine and cornutus. Female genitalia with small papilla analis fused dorsally; antrum usually tubular or funnel-shaped; corpus bursae rounded or ovate, signum present or absent.

Distribution. Glaucocharis Meyrick is distributed in the Palearctic, Oriental, African and Australian regions. It is distributed in the region of summer monsoon in China, which is presented by map herein ( Fig. 1 ). It shows that the species diversity is higher in the monsoon region south of 35°N, while it is conspicuously reduced in the region north of 35°N.

Diagnosis. Glaucocharis is close to Roxita Bleszynski, 1963 , but can be distinguished by the forewing with well-developed M1 and the valva without ventral fold in the male genitalia; in Roxita , the M1 vein of the forewing is absent and the ventral fold of the valva is present.
