The familySyrphidae consists of more than 6000 living species ofhoverfly. The internaltaxonomy of the family and the number ofgenera varies greatly between sources leading to considerable discrepancy across the literature. This is currently in the process of reorganization on the basis of phylogenetic studies but knowledge is still incomplete, especially in light of recent studies of larval characters suggesting relationships which don't correspond with the phylogeny based solely on adult characters.
The current classification is therefore still based on the morphology of adults and basically refers to the taxonomic scheme adopted by Thompson & Rotheray in the Manual of PalaearcticDiptera (1998), which divides the family into threesubfamilies and fourteentribes.
The nomenclature given here is derived partly from the BioSystematic Database of World Diptera (BDWD), and a working classification created by a group of molecular biologists which no doubt will alter greatly in the future.[2]
The subfamily Pipizinae was formerly considered a tribe within Eristalinae, but a recent phylogenetic analysis suggests it should be ranked as a separate subfamily (Mengual, 2015)[15].
This section contains a list of genera for which the bibliography does not provide a clear systematic position. These genera are not intended asincertae sedis: It is likely that they have been given a formal taxonomic description or been defined in a subsequent revision, but not in the works consulted.
^With regard to the subgenusH. (Pilinasica) consisting of four species endemic toNew Zealand, Thompson (2000, 2008) and Katzourakis et al. use the namePilinascia instead. It is likely this has been the result of a spread of a misspelling as in the literature there have been no formal reviews of the namePilinasica Malloch, 1922 with the exception of the proposal of a subgenus ofHelophilus.
^The genus was defined by Reemer (2008) to include two newly described species from Suriname,Surimyia minutula (=Paragodon minutulus) andSurimyia rolanderi. The review is quoted by Cheng & Thompson (2008) but not reported in BDWD where the speciesS. minutula is placed in the genusParagodon.
