Abstract: Specimens of the Chorthippus albomarginatus-group were studied from two localities near Ardovo in southern Slovakia. We analyzed the male courtship songs and the stridulatory peg number on the inner side of the hind femora. During recording of courtship songs, the stridulatory movements of the hind legs were also recorded. On the basis of the courtship song analysis and the measurements of the peg number, the specimens from both populations are regarded as C. oschei pusztaensis. However, deviations in song and leg movements for some specimens are consistent with hybridization between C. albomarginatus and C. oschei. Our study provides evidence C. albomarginatus and C. oschei hybridize in Slovakia.
