Scellus is a genus of flies in the family Dolichopodidae. [3] It is distributed in the Palearctic and Nearctic.
Males of the genus have a pair of flag-like appendages, known as "signa" (singular "signum"), that emanate laterally from between the 4th and 5th abdominal segments. These appendages are connected together by a band under the sternites, forming a U-shaped structure called the "cingulum". It has been suggested by researchers that these appendages are used for visual signalling or pheromone dispersal during courtship. The genus Hydatostega also has a cingulum, but much reduced, suggesting that Scellus and Hydatostega are closely related. [4] [5]
Argyra is a genus of flies in the family Dolichopodidae. The name "Argyra" comes from the Greek word for "silver".
Asyndetus is a genus of flies in the family Dolichopodidae. There are more than 100 species described for the genus, distributed worldwide.
Diaphorus is a genus of flies in the family Dolichopodidae. Lyroneurus is considered by some authors to be a subgenus of this genus.
Hydrophorus is a genus of flies in the family Dolichopodidae.
Liancalus is a genus of flies in the family Dolichopodidae. It contains at least 21 species distributed worldwide except in Australasia and Oceania. The genus includes some of the largest species in the family, with body length approaching 12 mm in some species.
Medetera is a large genus of flies in the family Dolichopodidae. It includes about 350 species worldwide. The adults are commonly found resting on vertical surfaces such as tree trunks, on which they have a characteristic vertical upright stance. Because of this stance, they are sometimes known as "woodpecker flies". Medetera adults are predators of soft-bodied arthropods, while the larvae are predators of bark beetle larvae.
Neurigona is a genus of flies in the family Dolichopodidae. It is a large genus, with over 150 known species.
Pelastoneurus is a genus of flies in the family Dolichopodidae.
Rhaphium is a genus of flies in the family Dolichopodidae. It is the largest genus within the subfamily Rhaphiinae, with over 200 species currently known.
Syntormon is a genus of flies in the family Dolichopodidae. It includes about 110 species worldwide, more than 50 of which were described from the Palaearctic realm.
Tachytrechus is a genus of long-legged flies in the family Dolichopodidae.
Thinophilus is a genus of flies in the family Dolichopodidae. It includes about 146 described species distributed worldwide. Most species of the genus are found in coastal habitats, while a few species are found in freshwater habitats.
Hydrophorinae is a subfamily of flies in the family Dolichopodidae. Several studies have found evidence that the subfamily in its current sense is polyphyletic.
Hydatostega is a genus of flies in the family Dolichopodidae. It was formerly considered a synonym of Hydrophorus, but was recently restored as a separate genus.
Gymnopternus is a genus of flies in the family Dolichopodidae. It was formerly placed as a subgenus of Hercostomus, but is now accepted as a separate genus.
