[email protected] Abstract: The collections of neuropterid orders from Bulgaria and Romania preserved in museums in Poland (Upper Silesian Museum in Bytom and Museum and Institute of Zoology in Warsaw) are identified. Faunistic information on 89 species is reported: 77 species from Bulgaria and 37 species from Romania (25 species from both countries). Coniopteryx (Xeroconiopteryx) atlasensis, Megalomus tineoides, Cunctochrysa cosmia and Neuroleon assimilis are new species for the fauna of Bulgaria. These first records shift the range borders of three species with 190 to 700 km northwards. Easternmost localities of Phaeostigma (Phaeostigma) pilicollis and Nothochrysa capitata and northernmost locality of Neuroleon assimilis are registered. The new localities outline the borders of the ranges of 20 species. Very rare species are Phaeostigma (Pontoraphidia) rhodopicum (Balkan endemic species), Libelloides lacteus (a single population in Romania), Coniopteryx (Metaconiopteryx) lentiae (in Romania), Coniopteryx (Holoconiopteryx) haematica and Sagittalata perla (both in Bulgaria), and Nedroledon anatolicus (in both countries). Key words: Raphidioptera, Megaloptera, Neuroptera, faunistics, Bulgaria, Romania. INTRODUCTION The fauna of all three neuropterid orders of Romania and Bulgaria is well explored and the species diversity is almost fully known.
