Bottom Line: A total of 12 gnat species are reported for the first time from Finland (3 Cecidomyiidae, 1 Keroplatidae, 8 Mycetophilidae), and the occurrence of Macroceranigropicea Lundström in Finland is verified.A photo of the ventral appendage of the gonocoxite of Brevicornusetigerum Zaitzev is provided for the first time.The male hypopygium of Mycetophilaharuspica Plassmann is redescribed.

ABSTRACT
A total of 12 gnat species are reported for the first time from Finland (3 Cecidomyiidae, 1 Keroplatidae, 8 Mycetophilidae), and the occurrence of Macroceranigropicea Lundström in Finland is verified. All material was collected from the Finnish Lapland, mainly from the north boreal ecoregion. Two of the recorded species are likely to be pyrophilous, associated with forest fire sites. A photo of the ventral appendage of the gonocoxite of Brevicornusetigerum Zaitzev is provided for the first time. The male hypopygium of Mycetophilaharuspica Plassmann is redescribed.

Figure 1550278: Ventral margin of gonocoxites.

Mentions: The original description of M.haruspica is rather uninformative, barely sufficient for identification purposes (Plassmann 1990, fig. 8). Proper redescription of this species is beyond the scope of this manuscript, but the morphology of the male hypopygium is reviewed here. The ventral lobe of gonostylus (vl gst, Fig. 11) has a conspicuous, helmet-like rounded lobe on dorsal margin and a small, hyaline spine next to it. Another prominent feature of vl gst is a long ventro-caudal spine, slightly bent beyond its mid-point (Fig. 11). Dorsal lobe of gonostylus (dl gst, Fig. 11) has a narrow, rounded lobe on the dorsal margin. The general shape of aedeagus is cordate, caudally tapering, apex incised and apical corners with a pair of narrow, hyaline lobes (Fig. 11c). 9th tergite is about as long as gonocoxite. Ventral margin of gonocoxites is undulating (Fig. 11d​). Based on the male hypopygium, the species is easy to separate from the other members of the vast genus Mycetophila.
