The genus Paragus (sin- Natural Resources, University of Alicante, Alicante, Spain gle representative of the tribe Paragini) was resolved as sister group of the monophyletic Scaeva-Eupeodes lineage. Inside this clade, a Neotropical radiation of Correspondence Ximo Mengual genera was well supported comprising Notosyrphus, Austroscaeva gen. nov., and Dio- Email: [email protected] prosopa.

Present results and the study of adult morphological characters prompted us to erect a new genus, Austroscaeva gen. nov., which includes four Neotropical species, that is, Austroscaeva melanostoma (Macquart, 1842) comb. nov., Austroscaeva occidentalis (Shannon, 1927) comb. nov., Austroscaeva patagoniensis (Kassebeer, 1999) comb. nov., and Austroscaeva penai (Marnef in Du sek &L
