The Palaearctic xiphydriid genus Konowia Brauns, 1884, is redefined and the component species are revised on the basis of a close examination of stability and taxonomic use of previously used and newly introduced characters. A new genus, Monoxiphia, is proposed for Konowia harai Shinohara, 2019, from Japan (Monoxiphia harai (Shinohara, 2019), n. comb.) and Xiphydriola Semenov-Tian-Shanskij, 1921, is synonymized with Konowia. Konowia is represented by the following four species: K. betulae (Enslin, 1911) from Europe, through Siberia, Korea to Japan (Hokkaido, Kunashiri Is.), K. kojimai, n. sp., from Japan (Hokkaido, Honshu), K. megapolitana Brauns, 1884 from Europe to the Russian Far East, and K. yasumatsui (Togashi, 1972) from Japan (Honshu, Shikoku, Kyushu). Xiphydriola amurensis Semenov-Tian-Shanskij, 1921, and Platyxiphydria nishijimai Togashi, 1998, are synonymized with K. betulae and a new species, K. kojimai, is described from Japan. Konowia yasumatsui is newly recorded from Honshu and Shikoku and the male of this species is described for the first time. A key to separate Monoxiphia, Konowia and four Konowia species is provided.
Palaearctic 锯角叶蜂属 Konowia Brauns, 1884，经重新定义，并根据对先前使用和新引入特征的稳定性和分类学用途的仔细检查，对其组成种进行了修订。日本的 Konowia harai Shinohara, 2019 被归入一个新属，Monoxiphia，即 Monoxiphia harai (Shinohara, 2019), n. comb.，并将 Xiphydriola Semenov-Tian-Shanskij, 1921 与 Konowia 同义。Konowia 由以下四个种组成：来自欧洲，经西伯利亚、朝鲜至日本（北海道、库页岛）的 K. betulae (Enslin, 1911)；日本的 K. kojimai，新种；来自欧洲至俄罗斯远东的 K. megapolitana Brauns, 1884；以及来自日本（本州、四国、九州）的 K. yasumatsui (Togashi, 1972)。Xiphydriola amurensis Semenov-Tian-Shanskij, 1921 和 Platyxiphydria nishijimai Togashi, 1998 与 K. betulae 同义，并描述了来自日本的一个新种 K. kojimai。Konowia yasumatsui 新记录于本州和四国，该种的雄虫首次被描述。提供了 Monoxiphia、Konowia 和四个 Konowia 种的区别特征。
