Diagnosis

Medium sized dark species, distinguished from other Gnophomyia by the structure of male and female genitalia (Fig. 1; see also Hancock (2008), fig. 6, 10).

Distribution

Palaearctic. Only recently discovered in Finland and Russian Karelia ( Polevoi and Salmela 2014, Starý and Salmela 2004).

Ecology

Saproxylic species, associated with different deciduous trees ( Krivosheina 2008). In Finland and Karelia, so far collected exclusively on aspen ( Hancock 2008, Halme et al. 2012). According to the authors' data, this species prefers huge wind-broken aspens with a diameter over 70 cm, fallen 7 years ago (Table 1). It favoured the trunks colonised by Lentaria afflata (RS=0.56, P<0.05) and Subulicystidium longisporum (RS=0.62, P<0.05), but seemed to avoid those decayed by Phellinus tremulae (RS=-0.56, P<0.05).

Conservation

Red-listed in Finland, category VU ( Penttinen et al. 2010).
