Abstract. A new tenthredinid, Doleriis {Neodolerus) anatolii Heidemaa and Zino-
vjev, n. sp., is described from the Russian Far East and South Korea. It is the first species
of the subgenus Neodolerus Goulet from outside the Nearctic Region. The subgenus now
includes eleven Nearctic and one Palearctic species. Shared characters between Neodol-
erus species and the Palearctic Dolerus (Poodolenis) vulneratus Mocsary are discussed.
