New taxonomic and faunistic records of fungus gnats (Insecta, Diptera) from Montenegro, Romania, and Serbia Author Kolcsár, Levente-Péter Author Salmela, Jukka text Check List 2017 2017-09-29 13 5 533 559 http://dx.doi.org/10.15560/13.5.533 journal article 10.15560/13.5.533 1809-127X 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.
