Revision of the genus Digonis (Lepidoptera, Geometridae): new species and new genera.

The taxonomic study of the Chilean Ennomini genera is still in its early stages. Within this group, the maculation patterns of Chilean species are uniform and often inadequate for distinguishing between many species, compounded by a lack of taxonomic revisions focused on the genera within the tribe. In this study, the genus Butler, 1882, is reviewed and redefined based on characteristics of wing patterns and genitalia. comprises the following five species: Butler, 1882, (Blanchard, 1852), Butler, 1882, Ramos-González & Parra, ., and Ramos-González & Parra, Additionally, Butler, 1882 is synonymized with (Blanchard, 1852), and all varieties of Butler, 1882, and are synonymized with their respective species. Furthermore, two new genera are introduced: Ramos-González & Parra, , erected for (Butler, 1882), , and Ramos-González & Parra, , established for Ramos-González & Parra, With the species and genus descriptions, a comparative diagnosis, genitalia illustrations for all species, and wing venation for each genus are provided.
