Review of Caryocolum (Lepidoptera: Gelechiidae) from the Russian Altai with description of two new species

In total, thirteen species of the genus Caryocolum Gregor & Povolny, 1954 (Lepidoptera: Gelechiidae) have been recorded from the Altai mountains in Russia so far. All available faunistic data are summarized and presented in detail. DNA barcodes of the mtCOI (cytochrome c oxidase I) gene of the majority of recorded species were studied. Molecular data and morphology support the following two species, which are described here as new to science: Caryocolum procurvella sp. nov. and C. atrumsp. nov. Caryocolum tetrameris (Meyrick, 1926) is recorded as a new species for Russia. Caryocolum blandella (Douglas, 1852) and C. viscariella(Stainton, 1855) are removed from the fauna of the Altai Republic due to misidentifications
