The complex of longhorn beetles in Rila Mt. in Bulgaria was studied by literature data and original biological materials. As a result, 126 taxa from six subfamilies were established, as follows: Prioninae (four taxa), Lepturinae (43 taxa), Necydalinae (two taxa), Spondylidinae (seven taxa), Cerambycinae (31 taxa) and Lamiinae (39 taxa). In this study, two new records for Rila Mt. (Stenurella nigra nigra and Xylosteus spinolae) and new localities or additional information for 24 cerambycid taxa were reported. The longhorn beetles belong to 18 zoogeographical categories and seven complexes. The European complex occupies a dominant position (37.3%), followed by the Palaearctic (23.8%), Eurosiberian (13.5%), Mediterranean (11.1%), European-Iranoturanian (7.1%), Balkan endemic (4.0%) and Holarctic (3.2%) complexes.

The present article lists distributional data about 19 taxa, which are new records for the Abruzzo, Lazio and Molise National Park, respectively – 16 jewel and 3 longhorn beetles. Data about 4 Italian endemics (2 buprestids and 2 cerambycids) are listed, and the category of risk according to the Italian IUCN Red Lists is also indicated for each species (when available); among the listed species, 1 is Endangered, 1 is Near threatened and 27 are Least concern.

The complex of insect inhabitants of old larval galleries of Saperda populnea (L.) (Coleoptera: Cerambycidae) was studied during the period 2000-2003 in 18 localities in Bulgaria. As a result, 32 insect species were reared from old S. populnea galls: Metopoplax origani (Kolenati) (Heteroptera: Lygaeidae), Malachius sp.
