Abstract - Revision of the Sibinia species of the Ethiopian region (Coleoptera, Curculionidae) - The revision of the Ethiopian weevils of the genus Sibinia Germar is performed. The 53 recognized species, 41 of which described as new, are placed in eight groups belonging to the nominotypical subgenus: 5 taxa remain incertae sedis. Every species is discussed as follows: extensive description with the range of variability, short diagnosis in English, comparison with closely related species, geographic distribution, available biological data, the illustration of essential morphological characters. Moreover, a key to species in Italian and English is given. Species are mostly distributed in southern Africa and appear to have as hosts plants of the family Aizoacecae. On the ground of morphological and biological data, some hypothetical phylogenetic relationships among Ethiopian groups, and between them and Palaearctic ones, are proposed.
