A picture key for semiaquatic and aquatic adults of Curculionoidea (Insecta, Coleoptera) from Brazil

Resumen

Abstract A pictorial key for the identification of aquatic and semiaquatic adults of Curculionidae associated with aquatic macrophytes from the Pantanal of Mato Grosso and the Amazon is presented for the first time based on the study of 13,252 specimens belonging to the two families of Curculionoidea (Brentidae and Curculionidae), six subfamilies, eight tribes, 22 genera and 24 species, most belonging to Tanysphyrini (Curculionidae, Brachycerinae). This key can be extrapolated to the Neotropical Region fauna due to the wide distribution of the included species, which is discussed in relation to taxonomic, biogeographical, and ecological studies.
