During the summer season in July 2006, 2007 and 2008 expeditions in the valley of the Pčinja River were carried out. During these expeditions 339 specimens of true bugs (Heteroptera) were collected from 7 different localities: Vogance, Jablanica, Budovija, Gornji Starac, Delinovica, Kozjak and Čivcije. 80 species from 22 families were identified. The majority of these species present two biomes: Mediterranean mountain pastures and forests of rocky grounds and European steppes with diverse grasses. The true bug’s mixed continental-Mediterranean fauna structure in the valley of the Pčinja River is a result of the specific climate conditions of that area. Paraparomius leptopoides (Bärensprung, 1859) is a new species for Serbian fauna
