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.

Es wird über insgesamt 48 Arten und Unterarten von Albanien, die zu 18 Gattungen und 8 Unterfamilien der Familie Buprestidae gehören, berichtet. Die 15 für die Fauna des Landes neuen Taxa sind mit einem Sternchen markiert. Mit den gesammelten neuen Arten erhöht sich die Zahl der Buprestiden, die aus Albanien bekannt sind, auf 111. Angefügt ist eine zoogeographische Analyse aller bekannten albanischen Buprestiden. Das Überwiegen von mediterranen Arten zeigt den starken Einfluß der Mittelmeerfauna auf die Zusammensetzung der Buprestidenfauna Albaniens.StichwörterColeoptera, Buprestidae, Albania, Mediterranean, Faunistics, Zoogeography.

Two new species of Agrilus Curtis, 1825 (Coleoptera: Buprestidae): Agrilus (Duttus) marietae sp. n. and Agrilus (Agrilus) naivashensis sp. n. are described from Kenya (East Africa).

Seven xylophagous insect species were established in stems and branches of Salix caprea L. during the period 1998-2003 in Bulgaria: Agrilus lineola lineola Redtenbacher (Coleoptera: Buprestidae), Aromia moschata (Linnaeus), Oberea oculata (Linnaeus), Saperda populnea (Linnaeus), Saperda similis Laicharting (Coleoptera: Cerambycidae), Synanthedon formicaeformis (Esper) (Lepidoptera: Sesiidae) and Rhabdophaga clavifex (Kieffer) (Diptera: Cecidomyiidae). From them, six parasitoid species were reared: Dolichomitus mesocentrus (Gravenhorst), Dolichomitus populneus (Ratzeburg) (Hymenoptera: Ichneumonidae), Stephanus serrator (Fabricius) (Hymenoptera: Stephanidae), Aprostocetus metra (Walker), Euderus caudatus (Thomson) (Hymenoptera: Eulophidae) and Billaea irrorata (Meigen) (Diptera: Tachinidae). D. populneus, E. caudatus and B. irrorata were connected with S. populnea; D. mesocentrus and S. serrator with S. similis; and A. metra with R. clavifex. Two parasitoids (A. metra and E. caudatus) had not previously been reported for the fauna of Bulgaria. The parasitoid-host relationships D. mesocentrus-S. similis and S. serrator -S. similis were established for the first time in this study.

Data about distribution and host plants of 19 species-group taxa from subfamily Chrysochroinae are presented. In this study, fourth known locality in Balkan Peninsula of Sphenoptera (Sphenoptera) cuprina cuprina (wery rare taxon in this region) was established. Distinguishing characters of S. (Chilostetha) laportei and S. (Ch.) substriata allowing their better identification are given as well.
