Synplasta gracilis Winnertz, 1864

Material examined. Figure 1. Romania: Vârghiș, Vârghiș Canyon, hornbeam-beech forest, 630 m a.s.l., 46.2174° N, 025.5435° E, 5 May 2014, Török E. leg., 2 males, DIPT-JS-2016-0254.

This is a rather widespread European species, here reported for the first time from Romania. Biology of the genus is poorly known, but S. gracilis has been reared from Mycoacia uda and Pleurotus dryinus ( Chandler 1993) , and Zaitzev (2003) referred to a record from Coprinus fruiting bodies. Synplasta species are generally rare in the boreal zone, mainly associated with deciduous or old growth forests (J. Jakovlev, pers. comm.), and thus, S. gracilis is Red-Listed (NT) in Finland ( Penttinen et al. 2010).
