The calling signal of the endemic to Altai-Sayan mountain system grasshopper Podismopsis altaica (Acrididae: Gomphocerinae) from the territory of the Russian Altai (State Nature Biosphere Reserve «Uvs Nuur Basin», the Mongun-Taiga site) is described for the first time. A comparison of the signals of P. altaica with P. poppiusi, the second species of Podismopsis also distributed in Altai Mountains, is given. It is shown that under lower temperature the repetition period of the series of sound of P. altaica is shorter than that of P. poppiusi. In addition, these two species are found in different habitats. P. altaica inhabits alpine stations, but P. poppiusi inhabits meadow and meadow-steppe stations. So the difference of habitats of P. altaica and P. poppiusi do not allow populations of these species to contact closely with each other.
