ABSTRACT. Illustrated descriptions of the male vibrational calling signals of 15 species of Palearctic Deltocephalinae from Europe, Central Asia, and the Russian Far East are published for the first time; signals of one more species were studied in a population located more than 2400 km from a previously studied locality. The signals of most species are characterized by strong intrapopulation variability. However, in two species for which signal recordings from localities situated at a distance of more than 2000 km apart were available, no geographical variability of signals was revealed. Signals of congeneric species can be similar in temporal patterns or, on the contrary, are very diverse and completely dissimilar in closely related species. Rhoananus hypochlorus (Paralimnini) produce pure-tone signals; signals of Macrosteles fieberi (Macrostelini) consist of noise and pure-tone components. Such signals were previously known in many species of Paralimnini but in Macrostelini they are described for the first time. In two species, distinct differences in frequency spectra between different components of the noise signals were revealed. Also, a brief overview and list of articles on vibrational signals of Deltocephalinae are presented.

KEY WORDS: leafhoppers, vibrational signals, variability, frequency spectra, pure-tone signals, Europe, Central Asia, the Russian Far East.
