Abstract
Eight new species of Hayesomyia are described on the basis of males from China: Hayesomyia aquila, H. cinctuma, H. fengkainica, H. galbina, H. rotunda, H. triangular, H. trina, and H. zayunica. Hayesomyia tripunctata (Goetghebuer) is reported from the Oriental Region for the first time and is redescribed and illustrated using Chinese specimens. A key to males of the genus of the world is presented and the generic diagnosis is emended.References
