The complex of species resembling Megaselia brevior (Schmitz) is revised. M. angustiata Schmitz and M.parvula Schmitz are reinstated as valid species. The following new synonyms are proposed: M. aspera Schmitz (male holotype only) is synonymised with M. leucozona Schmitz; M. ultrabrevis Schmitz, and its synonym M. pseudobrevior Disney, are synonymised with M. angustiata; and M. insecta Schmitz is synonymised with M. oxybelorum Schmitz. The female paratype of M. aspera is recognised as a female of M. parvula. A key to the Palaearctic species of this subgroup is provided.
