Bioacoustics of Pseudophlepsius abdykulovi

Hosts. Was collected from Glycyrrhiza sp. in the lower Ili valley (near the southwestern shore of the Balkhash Lake, Kazakhstan ), from Caragana sp. in southeastern Kazakhstan and in Kyrgyzstan on the southern shore of the Issyk-Kul Lake, from Halimodendron halodendron in Kyrgyzstan west of the Issyk-Kul Lake, and from G. uralensis in the northern foothills of the Kyrgyz Alatau (Northern Tien Shan, Kyrgyzstan ) ( Fig. 1 ). In Mongolia, Emelyanov (1977) collected specimens, most likely belonging to this species, from H. halodendron , Glycyrrhiza sp. , and Hedysarum mongolicum . Calling signal. Typically, the male calling signal is a syllable lasting for 0.5–2.0 s ( Figs 89–91 ). Syllables follow each other with irregular gaps from 1–2 up to 6–7 s and more. Each syllable consists of 4–12 discrete pulses; the initial pulse is somewhat longer than the subsequent ones and is separated from them by a longer gap ( Figs 93–98 ). Usually, on oscillograms at high speed, low-amplitude vibrations are discernible between high-amplitude pulses ( Figs 93–96 ). Sometimes a prolonged succession of additional shorter syllables consisting of two or three pulses each follows the main syllable ( Fig. 92 ); such a more complex signal can be classified as a phrase.
