Song. The male calling song of Chorthippus bornhalmi is a typical phrase lasts 1.1– 8.9 s (mean 3.2 ± 1.5). The phrase begins quietly and the maximum intensity is usually reached between 1/4–1/3 of the phrase (A in Figs. 14, 15 ), however, in some of the songs there is often a more gradual crescendo which occasionally lasts about half of the phrase. A phrase is composed of about 13–29 (24.4 ± 5.7) syllables each of which usually lasts about 96.7–127.6 ms (104 ± 2.8). According to song and leg movements, characteristic syllables of phrase in C. bornhalmi consist of two different parts. The closing hemisyllable includes characteristic 4 (rarely 5) tick pulses produced by the intense downstroke steps of the hind femur (B in Figs. 14, 15 ). The typical opening hemisyllable consists of a crescendo with no isolated pulses. Oscillographic analyses showed that there are usually 3 gaps in each of the closing hemisyllables, and that the gaps tend to become obvious toward the latter end of the phrase.

Distribution. The range of this species covers mainly the Balkans and central Greece except the most southern part and the Anatolian Peninsula ( Fig. 1 ). In Anatolia it is sometimes present, particularly in altitudes of 1500 m or higher. C. bornhalmi seems to be the most widespread species of this subgroup in Anatolia and previous records of C. brunneus in several earlier publications probably refer to C. bornhalmi .
