title: Review of the Neotropical genus Helenus White, 1879, with description of a new species (Hemiptera: Heteroptera: Aradidae).
abstract: Since the description of Helenus hirsutus by Champion (1898) from Panama, it was unclear if this species was a synonym of Helenus hesiformis White, 1879 that was described from Brazil. Now it was possible to locate and compare type specimens of both species, that resulted in recognising them as valid species. In this contribution, a third species, Helenus wachteli n. sp. is described from Peru, and a key to all species of the genus Helenus is presented.
