Figs 50–52 .

MATERIAL. Southeastern Kazakhstan, rocky desert between the Ili River and the lower Charyn River, about 4 km west of the Charyn River, 43.720° N, 79.324° E, from Nanophyton iliense U.P. Pratov , 14. VI .2022, signals of one male recorded at 24 ° C .

SIGNALS. The calling signal of the male from Southeastern Kazakhstan is a phrase lasting for 3.5– 10.0 s ( Figs 50–51 ). It consists of uniform syllables following each other with a period of 125–140 ms ( Fig. 52 ).

REMARKS. Signals of the male from Kazakhstan are almost indistinguishable from the previously described signals of the male from Astrakhan Oblast [ Tishechkin, 2018: 231; figs 142–148], despite the fact that the distance between recording sites exceeds 2400 km. The longer syllable repetition period in the signal of the male from Kazakhstan is explained by the fact that the recording was made at a lower temperature (24 oC in Kazakhstan vs 28 oC in Astrakhan Oblast).
