Remarks: Mycetophila lunata was interpreted widely in old sources, most of them have shown to belong to Mycetophila signatoides. M. lunata has not been confirmed from Sweden (see under doubtful and unrecognized species). Further confusion exists between M. signatoides and M. assimilis, especially after Zaitzev (1999a, 2003) illustrated another, undescribed species for M. signatoides. We follow here Chandler (2005) who regards M. assimilis as a junior synonym of M. signatoides and regards the Nearctic records of the species as doubtful.
