Isophya amplipennis Brunner von Wattenwyl, 1878

( Figs 54, 78 , 103 , 128 , 180 , 195 )

Isophya amplipennis Brunner von Wattewyl: Brunner von Wattewyl 1878 (sp.n.).

Morphological description: Brunner von Wattenwyl 1878; Brunner von Wattenwyl 1882; Ramme 1951; Bey-Bienko 1954; Can 1959a, b; Karaman 1961; Harz 1969; Heller 1988; Ünal 2003; Ünal 2010. Bioacoustics: Heller 1988.

The species is well characterised morphologically and acoustically in the cited references. Its karyology is not known.

Diagnosis: It well differs from I. speciosa and all other representatives of the group by the widened apex of male cerci (compare Figs 103 , 180 B with 104, 181B) and the structure of male stridulatory row (compare Fig. 180 A with 181A). Male stridulatory file bears 72–112 teeth (Can 1959a); in a specimen collected near Sögüt in Western Anatolia the file had 95 teeth and a length of about 2.7 mm ( Fig. 180 A). Male song (Heller 1988) consists of single elaborated syllables of three parts lasting about 3.4 s at>17°С (compare Heller 1988: p. 231, Abb. 33) and thus about 2–3 s at higher temperature.

Distribution ( Fig. 195 ) and phenology: Known from the southeasternmost Balkan Peninsula (S European Turkey) and NW Anatolia. Depending on the altitude nymphs may emerge quite early (possibly in February– March to April) and imagines occur between April–May and June (lowlands)–August (mountains).
