# List of Syrphidae genera

The family Syrphidae consists of more than 6000 living species of hoverfly. The internal taxonomy of the family and the number of genera 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 Palaearctic Diptera (1998), which divides the family into three subfamilies and fourteen tribes.
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.
The distribution of genera in biogeographic realms is derived from the biosystematics BDWD.

## Legend

* NT: Neotropical realm
* OR: Oriental realm
* PA: Palearctic realm

## Eristalinae

The subfamily Eristalinae (=Milesiinae) is subdivided into 9 tribes.

### Tribe: Brachyopini

(=Chrysogasterini Shannon, 1922)

### Tribe: Callicerini

(=Calliceratinae Brues & Melander, 1932)
* Callicera Panzer, 1809: NE NT OR PA
* Notiocheilosia Thompson, 1972: NT

### Tribe: Eumerini

(=Merodontini, Medorontinae Edwards, 1915, Medorontinae Bezzi, 1915, Medorontidae Glumac & Vujic, 1990, Nausigasterinae Shannon, 1921)

### Tribe: Milesiini

(=Xylotini)

#### Subtribe: Xylotina
### Tribe: Rhingiini

(=Cheilosiini Cockerell, 1917)

### Tribe: Volucellini
## Microdontinae

The arrangement of genera here follows the extensive revision carried out by Reemer & Ståhls (2013).

## Pipizinae

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).
* Cryptopipiza Mutin, 1998
* Heringia (=Cnemodon): NE PA
** Subgenera:
*** H. (Heringia) Rondani, 1856
*** H. (Neocnemodon) Goffe, 1944
* †Oligopipiza Nidergas, Hadrava, Nel et al., 2018 (a fossil genus from Middle Oligocene ~28 MYR-BP): PA
* Pipiza Fallén, 1810 (=Pseudopipiza): NE NT PA
* Pipizella Rondani, 1856: PA
* Trichopsomyia Williston, 1888 (=Halictomyia): NE NT OR PA
* Triglyphus Loew, 1840: AU OR PA
* Pipiza
* Heringia
* Pipizella

## Syrphinae

The subfamily Syrphinae is subdivided into 4 well established tribes. For table of genera, subgenera, authors and types see Mengual et al (2008)

### Tribe: Bacchini

(=Melanostomatini)

### Tribe: Syrphini

(=Chrysotoxini). In Mengual et al. (2008) this tribe was resolved into two groups.

#### Syrphini (Group undetermined)

* Agnisyrphus Ghorpade, 1994: OR
* Asiodidea Stackelberg, 1930: PA
* Dideomima Vockeroth, 1969: NE NT
* Doros Meigen, 1803: NE PA
* Lamellidorsum Huo & Zheng, 2005: PA
* Pelloloma Vockeroth, 1973: AF
* Rhinobaccha Meijere, 1908: OR
* Vockerothiella Ghorpade, 1994 : OR

### Tribe: Toxomerini
## Genera of uncertain affinities

This section contains a list of genera for which the bibliography does not provide a clear systematic position. These genera are not intended as incertae 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.
* Pia Philippi, 1865: NT
* Poliomyia Scudder, 1878: NE
* Spheginascia Meunier, 1901: PA
