Pteronemobius heydenii (Fischer, 1853)

P. heydenii is a hygrophilous and thermophilous species inhabiting lowland, but not overshadowed, wetlands, fens, banks of streams, rivers, and pools (Koschuh & Zechner 2000; Bedjanič 2004). In the CR, P. heydenii has been hitherto found only twice in Moravia, near Lednice (Čejchan 1985) and near Bzenec (Kočárek 2010). A recent finding of only one individual in Bzenec-Přívoz does not confirm an established population in this locality because that individual may represent a migrant. The locality and surrounding area where this individual was found have been carefully and repeatedly searched, but no other specimen of P. heydenii has been found. Given the occurrence of stable populations of the species in the north of Lower Austria (Zuna-Kratky et al. 2009), the species may be expected to occur along the Czech-Austrian border.
