Taxonomy

Eustylus was described for the first time by Carl Johan Schönherr in 1843 (p. 40). [2] The Central American species were treated by Champion. [3] Marshall 1916 offers a key to most species. [4]

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 [5] ). 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 [1] [6] [7]
