Based on a complex approach including morphological and molecular genetic methods, the taxonomic position of two casebearer moth species, Coleophora tsherkesi Falkovitsh, 1970 and C. isabellina Falkovitsh, 1970 (Lepidoptera, Coleophoridae), is discussed. On the phylogenetic tree based on the cytochrome oxidase subunit I gene (COI), the two species form a common cluster with species of the genera Ionescumia, Carpochena, and Goniodoma. Data on the molecular phylogeny and morphology justify the placement of Coleophora tsherkesi and C. isabellina in a separate genus Falkmisa Anikin et Dyomin, gen. n. Thus, the tribe Carpochenini includes three genera: Ionescumia, Carpochena, and Falkmisa.
