Rhegmoclema halteratum
(Meigen, 1838)
Rhegmoclema halteratum is a minute black fly in the Scatopsidae, commonly known as minute black scavenger flies or dung midges. The was described by Meigen in 1838. Members of this are characterized by reduced wing venation and are generally associated with decaying organic matter. Like other scatopsids, they are likely decomposers in nutrient cycling, though specific ecological details for this species remain poorly documented.

Identification
Distinguished from other Scatopsidae by wing venation patterns, particularly the reduced or modified referenced in the name. Separation from requires examination of genitalia and detailed wing venation; R. halteratum specifically shows characteristic halter-like vein reductions. Microscopic examination is necessary for reliable identification.

Taxonomic Note
The epithet 'halteratum' refers to halter-like or reduced structures, likely describing characteristic wing modifications. The Rhegmoclema is part of the diverse but understudied Scatopsidae, with many species poorly known ecologically.
