Based on the examination of more than 800 specimens of Phycitinae (Pyralidae) from the Galápagos Archipelago, 12 species are recognized. The new genus Shafferiessa is described to accommodate the two species: S. galapagoensis sp. n. and S. pumila sp. n. Macrorrhinia pinta sp. n. is also added to the number of endemic phycitines. New food plant records are provided for two species. Fundella agapella Schaus, 1923, is treated as a junior synonym of Fundella argentina Dyar, 1919.
