Abstract
The braconid genus Hylcalosia Fischer, 1967 of the fauna of Russia are reviewed. A new species, Hylcalosia livadiae sp. nov., from Primorskiy Territory is described. Based on new material, illustrated redescriptions of H. hymaenei Belokobylskij, 1992 and H. sutchanica Belokobylskij, 1992 are provided. Hylcalosia adsimilis Papp, 1994 is synonymised with H. sutchanica Belokobylskij, 1992 (syn. nov.). The most northern records in the Palaearctic Region, Amur Province of Russia, of the genus Hylcalosia and the species H. hymaenei and H. sutchanica are documented. A new key to all known species of this genus is provided.
