REMARKS. Korsunovskaya (2016) analyzed acoustic signals of males from the Platycleis albopunctata – grisea – intermedia group and supposed that only P. albopunctata is distributed in the former USSR countries. However, there are no data concerning acoustic signals of the

Platycleis albopunctata –grisea-intermedia group in the eastern part of their joint range. The nearest localities from where the acoustic signals of P. albopunctata were recorded are in

South Uzbekistan (Termez) (Korsunovskaya, 2016) and the Volga River Basin (Samarskaya

Luka) (Benediktov, 2017). This means the problem of determination of these katydids remains still unsolved for this territory.

DISTRIBUTION. Tuva: ET, UKH, UVS. – S Europe, S Siberia, SW Asia, the Caucasus ,

Kazakhstan, Middle Asia, NW China (?), Mongolia (?). This species was recorded from southeastern part Republic of Khakassia and southern part of Krasnoyark Region as P. intermedia or P. grisea (Miram, 1907; Ivanova, 1967).

ECOLOGY. The species usually occurs in the dry steppes and semi-deserts with abundant grasses. As a rule, its abundance is very low.
