New and interesting records of alien and native true bugs (Hemiptera: Heteroptera) from Bulgaria

New and interesting records of alien true bugs species (Corythucha ciliata (Say, 1832), Deraeocorisfla-vilinea (A. Costa, 1862),Oxycarenus lavaterae (Fabricius, 1787), Leptoglossus occidentalis Heidemann, 1910, Perillus bioculatus (Fabricius, 1775), Nezara viridula (Linnaeus, 1758)) in Bulgaria are reported. The spread pace of these species in Bulgaria and some their biological peculiarities, their potential threat to the native fauna and biodiversity in Bulgaria as a whole are briefly discussed. Deraeocoris flavilinea(A. Costa, 1862) is newly discovered among Bulgarian fauna. Oxycarenus (s. str.) lavaterae (Fabricius, 1787) is newly discovered in Greece. New data on the distribution of two native species with expanding range (Nagusta goedeli Kolenati, 1857; Arocatus longiceps Stål, 1872) are presented.
