| The habitus and genitalia are illustrated for the twelve species of Pterophoridae known from the Galápagos Islands (Ecuador). The status of one species is discussed, as it may be the unknown female of Postplatyptilia minima spec. nov. Five species are described as new: Postplatyptilia huigraica, P. minima, Platyptilia nigroapicalis, Oidaematophorus cristobalis and O. devriesi. Redescriptions and/or diagnoses are given for the other seven species. Lectotypes are designated for Pterophorus nephogenes Meyrick and Platyptilia brevipennis Zeller. A key based on adult external features is provided. Four species were found to be possibly endemic to the archipelago. New foodplant records are given for two species. |
