Abstract
Investigation of the male calling signals of Limotettix (Limotettix) striola (Fallén, 1806) in populations from central and southern European Russia, Northern Caucasus, and West Tien Shan, Kyrgyzstan demonstrated that they belong to the same species. Males of L. striola from West Tien Shan have a somewhat different penis shape and belong to a separate subspecies, L. striola ferganensis Dubovskiy, 1966. L. striola ferganensis from West Tien Shan differs from L. ferganensis sensu Hamilton (1983, 1994) from the Nearctic in the shape of penis in dorsal view. Apparently, L. ferganensis sensu Hamilton (1983, 1994) is a separate, possibly, undescribed Nearctic taxon.
