We describe a new genus, and a new species, of parasitoid--Tanzawana flavomaculata Watanabe & Kasparyan (Hymenoptera: Ichneumonidae: Ctenopelmatinae)--based on material collected in Honshu, Japan. As T. flavomaculata is found on Fagineura crenativora Vikberg & Zinovjev, 2000 (Hymenoptera: Tenthredinidae), a serious pest of beech tree, this parasitoid is an important natural enemy of F. crenativora that can be used for the biological control of this pest.
