Mycetophila deflexa Chandler, 2001

Material examined. Figure 1. Romania: Sânmartin, Ciuc Mts, Rugat Valley, young spruce forest along a small stream with old fallen trees, 950 m a.s.l., 46.2669° N, 026.0103° E, 25 August 2014, Kolcsár L.-P. leg., 1 male, DIPT-JS-2016-0008.

The species has a wide range, extending from Great Britain ( Chandler 2000) and Portugal ( Ribeiro 2003) to the Russian Far East ( Zaitzev 2003). In Europe the spe- cies is also known from France ( Chandler 2013), Finland (Jakovlev 2014), and Russian Karelia ( Zaitzev 2003). This species is very close to M. gratiosa Winnertz , and some of the records published as M. gratiosa may actually belong to M. deflexa (e.g., Polevoi 2001) from eastern Finland). The species is Red-Listed in Finland ( Penttinen et al. 2010), and it has been found from forests char- acterised by a high amount of dead woody material (J. Jakovlev, pers. comm.). Immature stages are unknown, but Mycetophila larvae live inside fungal fruiting bodies ( Ševčík 2010, Jakovlev 2011).
