Stigmatomeria crassicornis ( Stannius, 1931)

Material examined. Figure 1. Romania: Cluj-Nap- oca, Cartierul Mănăștur, hornbeam-beech forest near the city, 434 m a.s.l. 46.7497° N, 023.5467° E, 16 May 2014, Kolcsár L.-P. leg., 2 males, DIPT-JS-2016-0273.

The species is probably very widespread in Europe ( Chandler 2013) and has already been reported by Pârvu (2003, 2004a) from Romania. Stigmatomeria crassicornis is, however, close to S. obscura (Winnertz, 1864) , a species that had been for decades considered as a junior synonym of S. crassicornis (see Kjaerandsen et al. 2007, Salmela and Kaunisto 2015). Pârvu (2003) reported 2 females from Maramureș Depression, and the sex of the specimen examined from Piatra Craiului National Park was not specified ( Pârvu 2004a). Because Pârvu’s records may in principle also belong to S. obscura , the presence of S. crassicornis in Romania is verified herein. Larvae of the species may be associated with truffles ( Edwards 1925, Chandler 2010), but Jakovlev (2011) reared the species from Ascocoryne sarcoides on birch log.
