Abstract

Commatarcha galicicae Tokár & Srnka, sp. nov. is described from specimens taken in two south-eastern European localities, the Galičica Mountain in North Macedonia, and Dubova in Banat, Romania. The new species belongs to the genus Commatarcha Meyrick, 1935, which is new for the European Lepidoptera fauna. It resembles some Asian species from this genus and also the American species Bondia comonana (Kearfott, 1907) in external characters. In the genitalia of both sexes, it is similar to C. oresbia Diakonoff, 1989 but differs markedly in the colour and pattern of the forewing. The immature stages of the new species are unknown. Colour photographs of the adults and of the habitat are included with illustrations of the female and male genitalia.
