The external surface of facets of representatives of 19 families of Lepidoptera is discussed and illustrated. Two types of structures are recognized, this with nipples predominate.

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.
