Diagnosis

The imago of D. macroptera (Fig. 1) is large (up to 8 mm; about 5 mm in D. fasciata ), dark brown to blackish (yellowish-brown in D. fasciata ), while the wings are uniformly smoky (smoky with 2 light transverse bands in D. fasciata , cf. Kurina and Grootaert 2016: fig. 5A). The male and female terminalia are previously figured by Zaitzev ( Zaitzev 1978: fig. 6, Zaitzev 1994: fig. 24-3,7). The male terminalia of the studied specimen from Bulgaria are provided in lateral (Fig. 1), dorsal and ventral views (Fig. 2).

Conservation

Due to its rarity, D. macroptera is considered as critically endangered (CR) in the Czech Republic ( Ševčík 2005).

Biology

According to Landrock ( Landrock 1940) the species is rare in the mountain forests of Central Europe. This species has only been reared from two very similar species of bracket fungi: Phellinus igniarius ( Winnertz 1852) and Ph. alni (original data).
