Oreoleptis torrenticola
Zloty, Sinclair & Pritchard, 2005
Oreoleptis torrenticola is the sole in the Oreoleptis and Oreoleptidae, a family of flies established in 2005 based on this single species. The species was described from specimens collected in the Rocky Mountains, where its larvae inhabit torrential streams and have also been found in groundwater wells. This enigmatic dipteran represents a distinct lineage whose larval shows similarities to Athericidae and Tabanidae but possesses distinctive abdominal .

Identification
Larvae can be distinguished from similar aquatic dipteran larvae by the presence of long crocheted abdominal . They resemble larvae of Athericidae and Tabanidae but differ in proleg structure. No information is available for distinguishing from other Diptera.

Appearance
Larvae possess long crocheted false-legs () arising from the , distinguishing them from related . is poorly documented in available sources.
Habitat
Larvae inhabit torrential streams in montane environments and have been documented in groundwater wells. The type locality is in the Rocky Mountains.
Distribution
Known from the Rocky Mountains of North America. Specific range details beyond the type locality are not documented.

Larval stage is aquatic, developing in fast-flowing streams and groundwater. Details of and are not documented.
Similar Taxa
- AthericidaeLarvae share general but differ in having shorter or differently structured without the distinctive crocheted appearance.
- TabanidaeLarvae are superficially similar in aquatic and body plan, but Tabanidae larvae lack the long crocheted abdominal characteristic of Oreoleptis.

Taxonomic significance
Oreoleptis torrenticola is the type and only of both its and , making it critical for understanding the phylogenetic placement of Oreoleptidae within Diptera. The family was erected in 2005 based on larval characters that did not fit existing familial definitions.
Collection challenges
The has been collected from torrential streams and groundwater wells, suggesting specialized collection methods are required. No observations are recorded in iNaturalist as of the knowledge cutoff.
