Abstract: Phylogenetic relationships of theSphaerophorialineage (SphaerophoriaLe Peletier & Audinet-Serville and related genera) were inferred based on molecular characters, with the specific aim to infer the phylogenetic placement of the AfrotropicalSphaerophoriaspecies andLoveridgeana beattieivan Doesburg & van Doesburg. Three molecular markers were used, i.e., the mitochondrial protein-coding gene cytochrome c oxidase subunit I (COI) and the nuclear 28S and 18S ribosomal RNA genes. TheSphaerophorialineage generaExallandraVockeroth andLoveridgeanawere resolved within the genusSphaerophoria, and the IndomalayanEosphaerophoriaFrey was placed sister toCitrogrammaVockeroth, both related to a large species radiation from the New World.FaziaShannon andAllograptaOsten Sacken were recovered as non-monophyletic. Our results recovered two differentFaziaclades with dissimilar natural history resulted from our analyses, andAllograptaspecies were resolved into two clades, one with Nearctic and Neotropical species and a second clade with species from Oceanian, Indomalayan and Afrotropical Regions.Exallandrais considered a subgenus ofSphaerophoria,S. (Exallandra)stat. rev.,andSphaerophoria cinctifacies(Speiser)n. comb.a member of this subgenus together withS. loewiiZetterstedt. A newSphaerophoriasubgenus is designatedS.(Loveridgeana)stat. rev.to includeS. beattiein. comb.and the South African species, i.e.,S. quadrituberculataBezzi,S. retrocurvaHull, andS. aff.retrocurva. Based on their phylogenetic distinctiveness, functional traits, and ecological relevance we do recommend further ecological study and protection efforts for this Afrotropical group of pollinators.
