The genus Cleopus Dejean, 1821 is herein revised for the first time. Based on adult morphological characteristics, 18 species are recognized as valid. Thirteen species, all distributed in the Eastern Palaearctis or Oriental region, are described as new: C. aduncirostris sp. n.; C. cognatus sp. n.; C. confusus sp. n.; C. dohertyi sp. n.; C. hajeki sp. n.; C. lirenae sp. n.; C. longitarsis sp. n.; C. minutus sp. n.; C. pallidisquamosus sp. n.; C. parvidentatus sp. n.; C. philippinensis sp. n.; C. simillimus sp. n.; and C. subaequalis sp. n. Lectotypes of following two valid species and three synonyms were designated: Curculio solani Fabricius, 1792; Curculio pulchellus Herbst, 1795; Cionus setiger Germar, 1821; Curculio immunis Marsham, 1802; and Cleopus pulchellus rigidus Stephens, 1831. Neotypes of Curculio perpensus Rossi, 1792 and Cleopus pulchellus flavus Stephens, 1832 were designated. The following new synonyms of Cleopus pulchellus (Herbst, 1795) were established: Cleopus pulchellus var. flavus Stephens, 1831 syn. n. and C. pulchellus var. rigidus Stephens, 1831 syn. n.
