Abstract
Entimus serpafilhoi, a new species of the weevil genus Entimus from southeastern Brazil is described. It is distinguished from other species of the genus because it lacks the green, blue and gold iridescent scales typical of most other species. Superficially this species is similar to E. arrogans, which also lacks such scales, but the phylogenetic analysis shows it to be more closely related to E. excelsus and E. nobilis. The new species inhabits the ‘restinga’ forest, in contrast to other species from the state of Rio de Janeiro (Brazil) that are found in the Atlantic forest further from the coast.
