Acoustic signals and morphological characters of leafhoppers from Aphrodes bicinctus group from central European Russia.

摘要

Calling signals in males of Aphrodes species from the bicinctus group from the central part of European Russia were investigated. Within the studied area the group includes three species: xerophilous A. bicinctus and mesophilous A. centrorossicus feeding on various Fabaceae, and A. makarovi feeding on stinging nettle (Urtica dioica, U. urens). In some cases these three species were found in different biotopes of the same geographical locality. Morphological characters of the males whose signals were recorded as well as those of individuals from the same biotope were studied. Interpretation of A. bicinctus and A. centrorossicus is accepted after Zakhvatkin, 1953. Identification of A. makarovi is based on reinvestigation of the type series. The Lectotype of the last-named species is designated. A. bicinctus was also found in southern Kazakhstan and A. centrorossicus in north-eastern Caucasus and Tuva illustrating their wide distribution.
