Klimeschiopsis terroris auctt. from Spaina further case of cryptic diversity in European Lepidoptera (Lepidoptera, Gelechiidae, Gelechiinae).

A new species of Gnorimoschemini (Gelechiidae), Klimeschiopsis arnoldfransorum sp. nov., is described from specimens collected in Spain. The species is most closely related to Klimeschiopsis terroris (Hartig, 1938), with which it was hitherto mixed, but differs particularly by its small size with reduced yellowish-white forewing markings, the characters of the male and female genitalia, and the highly divergent DNA barcode (cytochrome c-oxidase subunit 1). Adult and genitalia of both sexes are figured. Finally, a checklist of the genus is provided.
