Taxonomic status of three acalyptrate dipterous species (Diptera: Milichiidae, Chiropteromyzidae)

The taxonomic status of three acalyptrate dipterous species, namely Leptometopa niveipennis fascifrons (Becker), Leptometopa broersei de Meijere and Milichia speciosa canariensis Becker, is revised. After the study of their type material, the following results have been obtained: (a) Leptometopa fascifrons (Becker) is a valid species, not a subspecies of Leptometopa niveipennis (Strobl); (b) Leptometopa broersei de Meijere belongs to the species Chiropterossy a wegelii Frey, this last species being a junior synonym of Leptometopa broersei; consequently its correct name is Chiropteromyta broersei (de Meijere) and it belongs to the family Chiropteromyzidae, not Milichiidae; and (c) Milichia canariensis Becker is a valid species and not a subspecies of Milichia speciosa Meigen.
