ABSTRACT. Illustrated descriptions of 17 species of Kybos from European Russia are provided, with data on distribution and host plants, and a key for their identification. Oscillograms of the male vibrational calling signals are presented for 12 species. Signal analysis showed that the taxon matsumurai, originally described as a subspecies of K. rufescens and similar to it in the shape of the abdominal apodemes, is in fact a subspecies K. butleri matsumurai Dworakowska, 1973, comb.n. The synonymy K. verbae Zachvatkin, 1953 = Empoasca (Kybos) ivanovi Logvinenko, 1980, syn.n. is established. Most Kybos species feed on several plant species from the same genus, however, quite often individual specimens were found on plants from other genera. In all such cases, conspecificity of males from different plants was confirmed by the calling signal analysis. Apparently, in some species of Kybos, adult specimens can feed on plants on which they cannot complete the life cycle and form a dense population.
KEY WORDS: morphology, vibrational calling signals, host plants, distribution, key to species.
