Distribution

Holarctic. Coelosia gracilis (Fig. 17) is here reported for the first time from the Palaearctic region. The species was described from the USA, California and Colorado ( Johannsen 1911) and according to Søli ( Søli 1997) the species has a wide range in the western part of the Nearctic region.

Ecology

Finnish sampling sites are headwater streams surrounded by boreal forests, a mountain birch forest and a rich spruce mire. Immature stages are unknown.

Taxon discussion

Coelosia gracilis is very close to the European species Coelosia truncata Lundström, 1909, and perhaps overlooked in the Palaearctic region.
