The Xiphydria annulitibia group is defined to include the following five species from northeastern Asia: X. annulitibia Takeuchi, 1936, from Japan (Hokkaido, Kunashiri Is., Honshu, Shikoku), Korea and Russia (Sakhalin, Primorskij kraj), X. kanba n. sp. from Japan (Hokkaido, Honshu), X. kastsheevi Ermolenko, 1979, from Russia (Primorskij Kraj), X. konishii n. sp. from Japan (Hokkaido, Honshu) and X. melanoptera n. sp. from Japan (Hokkaido). Xiphydria annulitibia is redescribed based on a long series of specimens, including the holotype. Three new species, X. kanba, X. konishii and X. melanoptera, are described and illustrated, and a key is provided for the five species. Xiphydria kastsheevi is excluded from the fauna of Japan. For X. kanba, notes on a rare successful case of branch trapping which yielded 87 adult specimens and observations on the adult emergence from a dead branch and peculiar drumming behavior of the male are given.
环胫剑蜂属（Xiphydria）的环胫剑蜂组被定义为包括来自亚洲东北部的以下五个物种：1936年由竹内定名的环胫剑蜂（X. annulitibia Takeuchi），分布于日本（北海道、国后岛、本州、四国）、韩国和俄罗斯（萨哈林岛、滨海边疆区）；新种堪波剑蜂（X. kanba n. sp.），分布于日本（北海道、本州）；1979年由叶尔莫连科定名的卡斯捷耶夫剑蜂（X. kastsheevi Ermolenko），分布于俄罗斯（滨海边疆区）；新种小西剑蜂（X. konishii n. sp.），分布于日本（北海道、本州）；以及新种黑翅剑蜂（X. melanoptera n. sp.），分布于日本（北海道）。基于包括正模标本在内的大量标本对环胫剑蜂进行了重新描述。描述并图示了三个新种，即堪波剑蜂、小西剑蜂和黑翅剑蜂，并提供了这五个物种的检索表。卡斯捷耶夫剑蜂被排除在日本动物区系之外。对于堪波剑蜂，记录了一例罕见的成功枝条诱捕案例，该案例获得了87只成年标本，并对成年个体从死枝中羽化以及雄性的特殊敲击行为进行了观察。
