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]
In general, Exophthalmus species are characterized by the smooth and broad longitudinal bridge running longitudinally across the rostrum. There is a lot of variation in sizes, density, coloration, and patterning of the scale coverage.
Species of this genus are present in Central America, northern South America and the Caribbean. [2]
