Ramburiellla (Palaeocesa) turcomana (Fischer von Waldheim, 1833)

Oedipoda turcomana Fischer von Waldheim, 1833: 384 .

Distribution in the Palaearctic region: South Eastern Region of Western Europe, Western Asia, Eastern Europe, Transcaucasia, Kazakhstan, Crimea, Middle Asia and Turkey ( Bei-Bienko & Mistshenko 1951; Demirsoy 1977; Bukhvalova & Vedenina 1998; Mol & Zeybekoğlu 2013).

Distribution in the Turkish Thrace: ÇANAKKALE: Gelibolu, Conkbayırı, Abide road, 10.VII.1969, 1 ♂; Gelibolu, Sütlüce Village, 10.VII.1969, 1 ♂, 1 ♀; İSTANBUL: Florya, vııı.1913 – ( Ebner 1919; Karabağ et al. 1971).

Material examined: ÇANAKKALE: Gelibolu, between Fındıklı-Değirmendüzü , 231m a.s.l, N: 40°24.903’ E: 26°31.873’, 24.VIII.2013, 1 ♂, 2 ♀♀, leg.: D. Şirin & E. Bayram ( Fig. 4 A). Calling song recorded from one male at 27 ˚C in the field by D. Şirin.

Description of song: The male calling song consists of a simple phrase which has series of syllables in irregular intensity ( Fig. 4 B). The calling song mostly lasts for 0.9– 2.5 s. The number of syllables varies from 20 to 45 in a phrase ( Fig. 4 C). The initial syllable has the shortest duration (15–30 ms), whereas the last has the longest duration (60–80 ms), and the other syllables have average durations (45–55 ms) between first and last syllables ( Fig. 4 D). The pulse numbers are not observed clearly in the syllable. This shows that the movement of both legs could not completely synchronize. Therefore, only a noisy oscillogram can be observed in a syllable.

Published song data, used for comparison: Savitsky 2002.
