Parachaetocladius
non-biting midges
Parachaetocladius is a genus of non-biting midges in the subfamily Orthocladiinae of the family Chironomidae, established by Wolfgang Wülker in 1959 and revised in 2020. The genus contains approximately 10 described species distributed across the Holarctic region, including both Palaearctic and Nearctic representatives. Species are typically associated with lotic freshwater habitats, particularly sandy substrates in springs and groundwater-fed streams. The genus is distinguished from related orthocladiine genera primarily through adult male genitalic characters, particularly features of the hypopygium.
