REMARKS. Almost simultaneously Tarbinsky (1931) and Hebard (1935) tried to synonymize Ae. reuteri with Ae. variegatus . Hebard supposed that the specific form of fore tibiae of Ae. reuteri ( Fig. 1 ) is associated with some physiological peculiarities of individual development. However, molecular data show that the studied species of the genus Aeropedellus form one well supported clade ( Chapco & Contreras, 2011), but Ae. reuteri is well separated from other species studied ( A. variegatus and two North-American grasshoppers, namely Ae. arcticus Hebard and Ae. clavatus (Thomas)) .

DISTRIBUTION. Russia (Republic of Khakassia, the southern parts of Krasnoyarsk Krai, and Irkutsk Oblast) ( Fig. 2 ). The species was also mentioned for Mongolia (Gankhuyag et al., 1971), but these data should be checked (see: Chogsomzhav, 1972; Baturina et al., 2024a).
