The Gelechiidae subfamilies Dichomeridinae, Anomologinae and Thiotrichinae in the Canary Islands are revised. We recognize seven species of Dichomeridinae, five species of Anomologinae and two species of Thiotrichinae. Four species are described as new: Dichomeris vivesi Falck & Karsholt, sp. nov., Helcystogramma brachmiaella Falck & Karsholt, sp. nov., Pseudosophronia confluella Falck & Karsholt, sp. nov., and Chrysoesthia diurnella Falck & Karsholt, sp. nov. A lectotype of Nothris castellana Schmidt, 1941, now Dichomeris castellana (Schmidt, 1941), is designated. Dichomeris castellana (Schmidt, 1941), Sitotroga psacasta Meyrick, 1908, and Polyhymno dumonti (Hartig, 1936) are recorded as new to the Canary Islands. We also present several records of species new to single Canary Islands. Dichomeris cisti (Staudinger, 1859) is removed from the list of Lepidoptera in the Canary Islands. The paper is illustrated with photographs of adults and genitalia of the new species as well as of other species when relevant. Analyses of DNA barcodes show that the identifications and distinctiveness of each species as well-supported and genetically isolated.
