Montana montana (Kollar, 1833) — Figs. 7 E1, 7E2.

Nomenclatorial remark. The name Montana montana milae Adamović, 1967 is not available because the publication ( Adamović 1967) does not contain anything which could be interpreted as a diagnosis required by Art. 13.1 of the International Code for Zoological Nomenclature ( ICZN 1999 ).

Localities: Austria, Burgenland, Illmitz, 1973 ( Ragge & Reynolds 1998) . Austria, Niederösterreich, Ebergassing , 2008 and 2012 (sic dates as given by Roesti & Keist 2009) . Czech Republic, Lanzhot, 2006 ( Kocarek et al. 2013). Ukraine, SE Ukraine, Lugansky reserve, 11.vi.1996, leg. A. Benediktov (2 males).

In the calling song verses of 1–2 s duration often alternate with pauses of about 3–4 s. According to Ragge & Reynolds (1998) and sound files in Roesti & Keist (2009) the verses consist of sequences of disyllabic echemes with syllable repetition rates around 40 to 70 Hz and echeme repetition rates of 15 to 30 Hz ( Fig. 7 E1). In two other recordings the echeme structure of the song could not be identified ( Table 1). However, animals from Ukraine obviously had a much lower syllable repetition rate. Their song did not show an echeme structure, but the syllable repetition rate agreed quite well with that of the echemes in the topotypical Central European populations ( Fig. 7 E2). The number of teeth in the stridulatory file did not differ between localities ( Fig. 6 B; Table 1).
