Unraveling a complex problem: Dichrorampha velata sp. nov., a new species from the Alps hitherto confounded with D. alpestrana ([Zeller], 1843) sp. rev. = D. montanana (Duponchel, 1843) syn. nov. (Lepidoptera, Tortricidae)

Analysis of wing pattern, genital morphology and results of DNA barcoding indicates that the name Dichrorampha montanana sensu auct. actually comprises two species. D. alpestrana ([Zeller], 1843) sp. rev. is considered as senior synonym of D. montanana (Duponchel, 1843) syn. nov., and a lectotype is designated for the latter name to fix the identity. After thorough search for possible synonyms, Dichrorampha velata sp. nov. is described and differentiated morphologically and with DNA barcodes from D. alpestrana and adults and genitalia of both species are figured. Dichrorampha velata sp. nov. is restricted to the European Alps and adjacent regions whereas D. alpestrana is more widespread with likely arctic-alpine disjunction and records from the Alps and the northern part of Great Britain.
