Abstract

During a faunistic and taxonomic survey of Ichneumonidae (Hymenoptera) in Vashlovani National Park, eastern Georgia (Sakartvelo), material collected mainly using Malaise traps was examined. As a result, 127 species belonging to 18 ichneumonid subfamilies were identified, including 30 species recorded for the first time from Georgia and 25 species newly recorded from the Caucasus region. In addition, two new species: Phaenolobus longiterebra Riedel sp. n. and Tycherus parastipator Riedel sp. n. are described based on diagnostic morphological characters. This contribution increases knowledge of the ichneumonid fauna of Vashlovani National Park, Georgia, and the Caucasus, and highlights the importance of the semi–arid and steppe ecosystems of eastern Georgia for parasitoid wasp diversity.
