Distribution

Palaearctic. Macrocera crassicornis (Fig. 6) has a rather wide range in central and southern Europe, also known from Near East and North Africa ( Chandler 2004, Zaitzev 1994). Included in the Finnish Red List assessment ( Penttinen et al. 2010), here formally reported as new for Finland.

Ecology

Reared from soil and dead coniferous wood. Finnish collecting sites are old-growth spruce dominated forests situated in the south boreal vegetation zone.

Conservation

Threatened fungus gnat species in Finland (VU, Penttinen et al. 2010).
