ABSTRACT. The attraction of males of Stygioides colchicus (Herrich-Schäffer, 1851) (Cossidae) to the sex attractant for males of Synanthedon andrenaeformis (Laspeyres, 1801) (Sesiidae) was clearly recorded for the first time. This attractant turned out to be a mixture of (3E, 13Z)-octadeca-3,13-dienyl acetate and (2E, 13Z)-octadeca-3,13-dienyl acetate in a ratio of 1:1. The use of this sex attractant made it possible to discover new localities of S. colchicus in Russia. The nomenclatural history of this species is discussed in detail.

KEY WORDS: Lepidoptera, Cossidae, Stygioides colchicus, new records, Crimea, Volgograd Region, sex attractants.
