Distribution

The type locality lies in Thessaly in Greece, where are the southernmost occurrences in Ossa and Pelion. The species is the distributed in northern Greece, North Macedonia, Bulgaria, Montenegro, Kosovo, southern and central Serbia and in the Romanian Carpathians. A small part of the distribution range lies in the Western Carpathians (central Slovakia, Bükk in Hungary), in Czechia it lives a restricted area in the valleys of Jihlava and Oslava. East of the Carpathians, H. thessalica lives in Moldova, Ukraine (scattered from the Podolian Upland up to Kharkiv) and Russia (Belgorod oblast near Valuyki, possibly introduced population is known from Ulyanovsk).[2][1]
