Exophthalmus cupreipes Champion (Coleoptera: Curculionidae) in Citrus Crops in Mexico

Abstract
The genus Exophthalmus Schoenherr (Coleoptera: Curculionidae) is a group native to the Neotropics and is widely distributed from Mexico to the Antilles and several countries of Central and South America (Vaurie 1961; O'Brien & Wibmer 1982; Wibmer & O'Brien 1986; Morrone 1999). This taxon comprises at least 95 described species (Zhang 2016) classified within the subfamily Entiminae (Alonso-Zarazaga & Lyal 1999; Morrone 1999). However, there is some difficulty in distinguishing this genus from related genera grouped within the Exophthalmus genus complex, which includes several species belonging to the Eustylini and Geonemini tribes (Vaurie 1961; Franz 2010, 2012).
