Boreoheptagyia
Boreoheptagyia is a genus of non-biting midges in the subfamily Diamesinae of the family Chironomidae. The genus was established by Brundin in 1966 and currently comprises approximately 19 described species distributed across the Holarctic region, with particular concentration in mountainous areas of Europe and Asia. Species in this genus are associated with cold, well-oxygenated lotic habitats and exhibit limited dispersal capacity, resulting in restricted, often isolated geographic ranges.
