Description of two new species from South Korea and Russian Far East with a key to the Palearctic species of the genus Brachyserphus Hellén (Hymenoptera, Proctotrupidae).

A taxonomic study of the Palearctic species of the genus Brachyserphus is presented. Two species are newly described as B. acuticaudatus sp. n. and B. semipunctatus sp. n. from South Korea and the Russian Far East. B. striatopropodeatus (Kolyada 1997 syn. n.) is synonymized under B. lucens (Provancher 1883) and a key to the Palearctic species is provided. [ABSTRACT FROM PUBLISHER]
