Elmohardyia atlantica-complex
Elmohardyia atlantica-complex is a within the long-legged fly Dolichopodidae. The group comprises morphologically similar that have not been fully resolved taxonomically, likely due to cryptic diversity and insufficient sampling. Members are small to medium predatory flies associated with forested . The complex is part of a Neotropical with limited published ecological or behavioral documentation.

Identification
Identification within the atlantica-complex requires examination of male genitalia and subtle differences in leg chaetotaxy and wing venation. External alone is insufficient to distinguish within the complex. The Elmohardyia is distinguished from related achalcine genera by the combination of a reduced or absent postpedicel , specific tarsal claw structures, and characteristic hypopygial morphology.
Habitat
Associated with Atlantic Forest and related forested in eastern Brazil. Specific microhabitat preferences within the complex remain undocumented.
Distribution
Eastern Brazil, within the Atlantic Forest biome. Precise range boundaries for individual within the complex are unresolved due to taxonomic uncertainty.

More Details
Taxonomic status
The atlantica-complex designation indicates that what was formerly treated as a single , Elmohardyia atlantica, has been recognized to contain multiple cryptic or poorly differentiated species. Formal species descriptions may be pending. This pattern is common in understudied Neotropical dolichopodid where molecular and fine- morphological analysis reveals hidden diversity.
Research needs
Resolution of the complex requires integrated taxonomic study combining molecular data (COI, nuclear markers), detailed male genitalic examination, and expanded geographic sampling throughout the Atlantic Forest region.
