Abstract

New material from Réunion has been examined from several collections. Description of Mascaromyia martirei Grichanov, n. sp. is provided. M. leptogaster (Thomson, 1869) is recorded on the island for the first time. Mascaromyia digrediens Meuffels & Grootaert, 2007 is transferred to the genus Bickelia Grichanov, 1996 thus becoming Bickelia digrediens (Meuffels & Grootaert, 2007), n. comb. New records and a key to known species of Mascaromyia Bickel, 1994 from Réunion are also given. Presently 29 species of Mascaromyia are known from western Indian Ocean islands, including 11 species from Réunion. An adaptive radiation of the genus on the islands is briefly discussed.
