Coleophora nepetellae Baldizzone & Nel, a new species of the C. lixella group (Lepidoptera, Coleophoridae) from France and Italy

Coleophora nepetellae Baldizzone & Nel, sp. n. is described from the southern Alps (Italy and France). It belongs to the Coleophora lixella species group. Its host plants are Nepeta nepetella L. (Lamiaceae) and an unidentified Poaceae. The fifth instar larva, its case, the adult habitus, and genitalia are illustrated. The species is compared to C. nevadella Baldizzone, 1985, here newly confirmed from France and whose larvae feed on Nepeta latifolia DC. in the Eastern Pyrénées. DNA barcodes are shown to be distinct and congruent with morphological differences among species of the lixella group. Barcodes revealed that C. tricolor Walsingham, 1889, formerly known only from Great Britain, is also present in France and Greece
