Exophthalmus is a genus of broad-nosed weevils in the family Curculionidae.[1] It contains 85 described species.[2][3]

Exophthalmus was named for the first time by Carl Johan Schönherr in 1823 (column 1140).[4] It belongs in the tribe Eustylini.[1]

In revising the Jamaican species, Vaurie offers an overview to the genus and its taxonomic conflicts.[5] A preliminary phylogeny for Exophthalmus and its allies was presented by Franz.[6] It is part of the so-called "Exophthalmus genus complex" [6] which involves members of the genera Diaprepes, Compsus, Lachnopus, among others. Based on morphological and molecular evidence, it has been proposed that the genus needs to be reclassified to better reflect the actual distribution of natural clades.[7]
