Butterflies of the genus Redonda Adams & Bernard (Lepidoptera: Nymphalidae: Satyrinae) are endemic to the Andes of Venezuela. They comprise a monophyletic group of five allopatric taxa, females of which show various degrees of wing reduction and ability to fly. The female of Redonda bordoni Viloria & Pyrcz sp. nov. appears to be brachypterous and incapable of sustained flight, a phenomenon previously unknown within the Rhopalocera.
