Ten species of broad nosed weevils belonging to Entiminae, Naupactini, are recorded as harmful for roots of citrus in São Paulo state, Brazil. Most species belong to Naupactus Dejean, N. rivulosus (Olivier), N. tarsalis Boheman, N. curtus Boheman, N. navicularis Boheman, N. versatilis Hustache, N. ambiguus Boheman, and N. cervinus Boheman; one species was assigned to Teratopactus Heller, T. nodicollis (Boheman); one to Parapantomorus, P. fluctuosus Schoenherr (Boheman) and one to Symmathetes Schoenherr (a genus herein reinstated), S. kollari Schoenherr. Larvae live in soil and bore on roots of the trees, causing more damages than adults, that feed on leaves. The main goal of this paper is to provide a key, diagnosis and habitus photographs of the species, in order to facilitate their identification. We also provide information on their geographic range in Brazil and previous plant associations, and we discuss some relevant biological features, especially those related to oviposition habits.
