A total of 18 Palaearctic and Oriental species of Endomia are treated. Two of them are described as new: Endomia rameshi sp. n. (South India) and Endomia gracilis sp. n. (South Vietnam). A new synonymy Endomia arabica Pic, 1913 (= Endomia longicornis Pic & Hawkins, 1955, syn. n.) is proposed. Lectotypes are designated for the following seven species: E. indica (Laferté, 1848); E. euphratica Krekich-Strassoldo, 1926; E. nana Krekich-Strassoldo, 1926; E. gratiosa Krekich-Strassoldo, 1926; E. lumulata Krekich-Strassoldo, 1926; E. baeri (Pic, 1902); E. malayana (Pic, 1895).
