In this study, the fauna of Papilionoidea and Hesperioidea (Lepidoptera) from Sultandağları Mountains, Afyonkarahisar province, in Turkey were investigated. Field collections were conducted between March and August from 1997 to 2001. Individuals were collected from 110 field surveys. The specimens belonged to 131 species in seven families, including Papilionidae (6 species), Pieridae (17), Libytheidae (1), Argynnidae (21), Satyridae (24), Lycaenidae (45), and Hesperiidae (17). Tomares nesimachus (Oberthür, 1893) was identified for the first time in Afyonkarahisar and fourteen of the 131 species were new records for the Lepidoptera fauna of Sultandağları Mountains.
