Figs 16–20 .

MATERIAL. Kyrgyzstan, Western Tien-Shan Mts. , Chatkal Mtn. Range, Sary-Chelekskiy Nature Reserve, environs of Arkyt village, 30.VI.2009, signals of one male recorded at 21–22 °C .

SIGNALS. The male calling signal is a complex phrase lasting for 6–8 s ( Figs 16–17 ). The phrase consists of three syllables lasting for 0.7– 1.0 s each, alternating with shorter syllables lasting for about 100–200 ms or with single discrete pulses.The end parts of longer syllables usually differ somewhat from the main parts in the pulse repetition period or in their amplitude ( Figs 19–20 ), but sometimes these differences are indistinct ( Fig. 18 ).

REMARKS. The type locality of this species (environs of Ala-Buka Village ) is situated on the same mountain range ca 60 km southwest from the recording site [Dubovsky, 1966] .
