Austalis is a genus of Hoverflies, from the family Syrphidae, in the order Diptera.

Formerly members of this genus were considered part of Eristalis though as rather a distinct group. They are very similar to Eristalinus , but Austalis is defined by having a postalar pile tuft but lacking the pile on posterior portions of the anepimeron and lacking the patterning on the eyes typical of Eristalinus. They also share a distinct metallic colouring. Little is known of their life histories but the adults have been recorded feeding at Eucalyptus flowers. [1]

Systematics

List created by Thompson (2003) in defining the new genus. [1]

A further dozen species are known from the Oriental and Australasian regions but await formal description.

Eristalis is a large genus of hoverflies, family Syrphidae, in the order Diptera. Several species are known as drone flies because they bear a resemblance to honeybee drones.

<span class="mw-page-title-main">Microdontinae</span> Subfamily of flies

The subfamily Microdontinae contains slightly more than 400 species of hoverflies and, while diverse, these species share several characteristics by which they differ from other syrphids. The Microdontinae are myrmecophiles, meaning they live in the nests of ants. Larval Microdontinae are scavengers or predators in ant nests, and, in contrast to other syrphid larvae, have no readily apparent body segmentation. Some species also do not exhibit the typical adult flower-visiting behaviour of other hoverflies, but instead remain near their larval host colonies.

<i>Microdon</i> Genus of flies

Hover flies of the genus Microdon are unusual among the Diptera. Like other members of the subfamily, they are myrmecophiles, meaning they inhabit the nests of ants.

<i>Eristalinus</i> Genus of flies

Eristalinus is a genus of hoverfly. Most species have very distinctive eye marking in the form of spots or banding, though these features may fade on some preserved specimens. Most are stout flies, and are nimble flyers, even compared to other hoverfly species.

Kertesziomyia is a genus of 14 Hoverflies, from the family Syrphidae, in the order Diptera.

Archimicrodon is a genus of hoverflies. Many of the species in this genus were moved from Microdon by Reemer & Ståhls (2013). Previously, it had been described as having three known species.

Mixogaster is a genus of hoverflies native to North America and South America, with 21 known species. Mixogaster is distinct by lacking an appendix on vein R4+5, having a reduced and bare metasternum, an unarmed scutellum, and usually an appendix on vein M extending in cell R4+5. Larvae are found in ant nests.

Paramixogaster is a genus of hoverflies, with 25 known species. Paramixogaster has an appendix on vein R4+5 that is absent in Mixogaster.

Spheginobaccha is a genus of hoverflies, with 15 known species. The genus is readily separated from other microdons by the incomplete metathoracic bridge, round/oval basoflagellomere, occiput with a dorsolateral crease, and other characters.
