Bioacoustics of Isophya yaraligozi

diagnosis · Plazi

Supplement to the description and a diagnosis : Large for the genus. Male tegmina slightly longer than pronotum with approximated CuP and CuA (similarly to their position in I. rh. rhodopensis ). In the studied specimen the stridulatory file was 3.4 mm long with 140 teeth ( Fig. 140 A). Female stridulatory apparatus is shown in Fig. 140 C. Male cercus tooth ( Fig. 140 B) is large, somewhat resembling that of I. tosevski , but placed almost apically, which differs it from the other representatives of the I. modesta group. The tip of cerci is not incised. The song consists of isolated or two loosely grouped short syllables without after-clicks.

Bioacoustics : The song ( Fig. 146 ) was studied in two males at 23–24°С. The syllables were produced at large intervals isolated or, when grouped by two, at intervals of 1.5–6 seconds. Syllables lasted 197–269 ms (mean 233±24; n=8) and contained 50–58 impulses (mean 55±3; n=8) with impulse period of 3–8 ms (mean 4.2). The song frequency ranges between 10 and 24 kHz with a maximum at 15–16 kHz.
