2.1. Complex Isophya rectipennis

Characteristic with more primitive morphology and song in comparison with the other representatives of the group. Slender species. Hind femora are without ventral spines. CuP is weak and short, CuP and CuA are widely separated. The venation of female tegmen is clearly parallel or to some extent reticulate (in I. triangularis ). The ovipositor is short (7–9 mm). The song (at least in I. rectipennis ) consists of short syllables arranged in phrases. The cerci are elongated, slender. The complex includes two species having widely isolated ranges of distribution— I. rectipennis (E Balkans and NW Asia Minor ) and I. triangularis ( Lebanon and Syria; see Sevgili and Heller 2003).
