Distribution. Widespread in Europe, Russia (European part, northern Caucasus) and Turkey.

Status in CZ. Previously recorded only from southern Moravia: Valtice (Olejníček 1982, erroneously as Medetera tertia), Dolní Věstonice, Pálava (Olejníček 1998), and from six localities within Podyjí National Park (Olejníček et al. 2005). The first records from Bohemia are presented herein.

Ecology. Medetera muralis has been collected from soils, walls and trunks of deciduous trees (Pollet et al. 2011). The above listed records originate mostly from rocks and rocky outcrops.
