The objective of this paper is to bring about a diagnosis of four species of root weevils, recorded for the first time causing damage in citrus grooves of the states of Sao Paulo and Minas Gerais, Brazil. A key for the identification of 14 species harmful for citrus in these states is provided as well as a study on their occurrence and distribution. The four species treated in this paper belong to the genus Naupactus Dejean (Curculionidae: Entiminae: Naupactini): N. bellus Boheman, N. cinerosus Boheman; N. decorus (Fabricius) and N. virens Boheman. Among the 14 species included in the key, eleven belong to Naupactus [N. ambiguus Boheman, N. bellus Boheman, N. cervinus Boheman, N. cinerosus Boheman; N. curtus Boheman, N. decorus (Fabricius), N. navicularis Boheman, N. rivulosus (Olivier), N. tarsalis Boheman, N. versatilis Hustache and N. virens (Boheman); one to Teratopactus Heller (T. nodicollis (Boheman)]; one to Parapantomorus Emden [P. fluctuosus (Boheman)] and one to Symmathetes (S. kollari Schoenherr). The citrus root weevils occur in all citrus grooves of Sao Paulo and Minas Gerais, and the species diversity is higher in the center-south area of Sao Paulo. N. tarsalis, N. versatilis and P. fluctuosus are present in the highest number of localities.
