Eustylus

Eustylus is a neotropical genus of broad-nosed weevils in the subfamily Entiminae, tribe Eustylini.

Taxonomy

Eustylus was described for the first time by Carl Johan Schönherr in 1843 (p. 40). The Central American species were treated by Champion. Marshall 1916 offers a key to most species.

Description

One of the most salient features of Eustylus is its broad antennal scape, densely and uniformly covered by scales (see Fig. 7F in Girón 2020 ). Some species bear a spine on the inner margin of the profemur, which is unusual for eustylines. Most species are uniformly covered by brown scales forming different patterns; metallic green species are also found.

Distribution

The genus Eustylus ranges from Mexico to Paraguay, with some species represented in the Caribbean
