Harmandiola
Harmandiola is a genus of gall midges (family Cecidomyiidae) comprising 14 described species distributed across the Holarctic region. These small flies are notable for inducing galls on woody host plants, specifically species of poplar (Populus), chestnut (Castanea), and hickory (Carya). The genus was established by Skuhravá in 1997. Species-level taxonomy has been revised multiple times, with several species transferred from related genera.
