The first sighting of Isophya posthumoidalis (Orthoptera, Tettigoniidae) in Ukraine and observations on its biology and acoustics

Abstract

Isophya posthumoidalis is a rare species native to Central Europe that is only found in a very small area of Poland, Slovakia, and Romania. Since Bazyluk’s description in 1971, it has been regarded as endemic to the Eastern Bieszczady mountains. In 1976, we discovered this species in Zakarpattia Province (Transcarpathia, Ukraine), but the records were not published, because there were no males available. Due to the analysis of a male’s acoustical signals in 2022, further confirmation was obtained.
