Fazia is a genus of hoverflies, formerly treated as a subgenus of Allograpta (e.g., [1] ), but now treated as a genus, though not monophyletic as presently defined. [2]
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.
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.
Platycheirus is a large genus of hoverflies. They are also called sedgesitters.
Allograpta is a very large and diverse genus of hoverflies present throughout the world except most of the palearctic region. The adults are brightly coloured flower pollinators and most larvae have a predatory feeding mode involving soft-bodied sternorrhynchans. Certain species have diverged from this and their larvae have been found to be leaf-miners, stem-borers or pollen-feeders.
Criorhina is a genus of hoverflies. Medium to large sized species, black or greenish black, with or without light ground markings mimicking bumblebees. The head is much flattened and broader than the thorax. The antennae are situated upon a prominent conical frontal process, The face is moderately produced below the eyes, downward or forward, in profile. The eyes are bare. The abdomen is elliptical or very short oval. Larvae found in rot holes or decaying hardwoods
Omegasyrphus is a genus of hoverflies, with five known species. These are small Microdontinae flies with a distinctive abdominal shape; the second segment is widened, flattened, and flared, with its lateral margin subcircular, thickened, and rounded, and the rest of abdomen narrowed and cylindrical. Larvae are found in ant nests. They are native to southern North America. The genus was previously treated as a subgenus of Microdon.
Copestylum is one of the largest genera of hoverflies in the Americas. It comprises more than 300 species, of which only four have been found outside the Americas, having probably been introduced by the importation of cacti in which the larvae live.
The Syrphini are a tribe of hoverflies.
Ocyptamus is a large and diverse genus of over 200 species of hoverfly mostly found in the Neotropical region. It is likely that many of these species will be discovered to be synonyms though many others await description.
Palpada is a genus of 85 neotropical and nearctic flower flies or hoverflies This genus is often colorful and bee-like. It is in the tribe Eristaliini containing dozens of genera Common sister genera include Eristalis (99 species), Meromacrus (43 sp.), Eristalinus (100 sp.) and Helophilus (50 sp.). The genus palpada is distinguished by:
Salpingogaster is a genus of syrphid flies in the family Syrphidae. There are at least 30 described species in Salpingogaster.
Peradon is a genus of hoverfly from the Neotropical realm, containing 31 species. Many of the species were originally described in the genus Microdon.
Pseudoscaeva is a genus of hoverfly in the Neotropical region, formerly included in the genus Ocyptamus, which was split after researchers determined it was not monophyletic.
Orphnabaccha is a genus of hoverfly in the Neotropical region, formerly included in the genus Ocyptamus, which was split after researchers determined it was not monophyletic.
Hybobathus is a genus of hoverfly in the Neotropical region, formerly included in the genus Ocyptamus, which was split after researchers determined it was not monophyletic.
Allograpta robinsoni is a two-winged species of hoverfly found on the Malay peninsula, first described by Charles Howard Curran in 1928. It is an oriental species in the Allograpta obliqua species group.
