Distribution

European, so far reported only from Fennoscandia. The species (Fig. 10) was described from North Sweden (Abisko) ( Plassmann 1990), and later findings are also from the northern part of the country ( Kjaerandsen et al. 2007b). Only once recorded from North Norway, Alta ( Søli and Rindal 2012). Here reported from six sites in north boreal Finland.

Ecology

The species has been collected from both subalpine and boreal ecoregions, but detailed habitat descriptions are lacking in the literature. Finnish sampling sites are small lotic water bodies surrounded by old-growth boreal forests.

Taxon discussion

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 .
