New taxonomic and faunistic results are presented on the genus Evergestis Hübner, 1825 of the subfamily Glaphyriinae on the basis of a sample collected in the province Dhofar in Oman in 2019.  Analysis of external characters, of the male and female genitalia resulted in the attribution of the specimens to two different species of the genus Evergestis Hübner. Comparison of the species with closely related congeners revealed significant differences in external characters and in the male and female genitalia. These differences result in the descriptions of the new species Evergestis viridifuscalis sp.nov. and Evergestis angularis sp.nov.. The adults, the tympanal organs, the male and female genitalia are described and figured. The key differential features are listed.
