Distribution

New to Finland. Global distribution poorly known due to confusion with Medetera muralis ( Fallén, 1823) ( Pollet 2013).

Discussion

Medetera belgica was based on a single female Parent 1936. Negrobov and Stackelberg 1972 redescribed the species based on male specimens from the Kola Peninsula in Russia, some 2,500 km away, without studying the holotype of Medetera belgica . It is certainly possible that the Finnish specimens identified as Medetera belgica sensu Negrobov are not conspecific with Parent's original types. Medetera belgica was synonymised with Medetera muralis by Grichanov (2002), but this synonymy has been disputed ( Pollet 2013). In Finnish material the leg colour characters and differences in male genitalia between the two species ( Medetera muralis and Medetera belgica sensu Negrobov) are well defined and constant.
