ABSTRACT. Calling signals of 15 species of Gomphocerinae grasshoppers (Orthoptera, Acrididae) from Russia and adjacent territories are described and illustrated with oscillograms at different speeds. Signals of each species were recorded in several localities remote from each other. Geographical variation of signals temporal pattern is discussed. Ch. albomarginatus caliginosus Mistshenko, 1951 is regarded as separate species Ch. caliginosus Mistshenko, 1951, stat. n. basing on investigation of acoustic signals.
