Swedish records of Mycetophila perpallida
Original and used names: Mycetophila perpallida Chandler, 1993:6. = Mycetophila grisea Zetterstedt, 1852:4208.
Swedish sources: Mycetophila grisea: Zetterstedt 1852:4208 [JÄ]; Fungivora M. agarici (grisea): Wahlgren 1921:195 [JÄ]; Mycetophila perpallida: Kjærandsen et al. 2007:84 [Boreal–boreonemoral — •SM•SÖ•JÄ•]; Jakovlev, Kjærandsen & Viklund 2008:40 [SÖ].
World distribution: Western Palaearctic; widely distributed in Europe.
Remarks: We find the holotype of M. grisea to be identical to M. perpallida as described by Chandler (1993), but retain M. perpallida pending a review of other possible synonyms with precedence. A widespread and probably common species in Europe, but undoubtedly confused with Mycetophila fungorum in earlier sources. Very similar to M. fungorum from which it can be distinguished only by details of the male terminalia.
