Based on data from literature, collections, FloVegSi database and expecially results of our own research, we have identified 117 species of bark beetle (Scolytinae) and one species of pinhole borers (Platypodinae) for the fauna of Slovenia. In Slovenia, a list of bark beetle was published in 1988 (Titovšek 1988) and it included 69 species. The updated list of the bark beetle fauna is mainly the result of the analysis of additional catches in pheromone traps when monitoring the vectors of the pine wood nematode. The material lists 48 additional species, 42 of which are native and 6 non-native. New Slovenian names are proposed for all considered species. The historical review of research (between 1858 and 2023) on the species in Slovenia is presented. Systematic overview, locations and distribution maps of all species of bark beetle and pinhole borer are given. The microlocations of the finds on host plants and forest products or the types of traps with used attractants are presented. Color photos for most of the discussed species are provided. The ecological and biological characteristics of the species are briefly presented. The ecological and economic importance of bark beetles and pinhole borers is assessed.
