A review of the ground beetle genus Anisodactylus Dejean, 1829 of the Russian Far East is given. The fauna of this region includes four species of two subgenera: A. (Pseudanisodactylus) signatus (Panzer, 1796), A. (P.) punctatipennis Morawitz, 1862, A. (Anisodactylus) tricuspidatus Morawitz, 1863 and A. (A.) arsenjevi sp. nov. The latter species is described from several localities in the southern Primorye Territory (type locality: 1 km S Beltsovo Village, Arsenjevka River floodplain, Yakovlevka District); it is rather distinct among the Palaearctic species and most similar in general habitus to some Nearctic species, especially to A. (A.) harrisii LeConte, 1863. Anisodactylus (A.) tricuspidatus is recorded for Russia for the first time. A lectotype of A. punctatipennis is designated. The distribution and distinctive characters of all four species are discussed, and a key for their determination is provided; their habitus and male and female genitalia are illustrated.
本文对俄罗斯远东地区的地甲虫属异形步甲属（Anisodactylus Dejean，1829）进行了综述。该地区的动物区系包括两个亚属的四个物种：异形步甲（伪异形步甲亚属）指名亚种（A. (Pseudanisodactylus) signatus (Panzer, 1796)）、异形步甲（伪异形步甲亚属）点翅亚种（A. (P.) punctatipennis Morawitz, 1862）、异形步甲（异形步甲亚属）三齿亚种（A. (Anisodactylus) tricuspidatus Morawitz, 1863）和异形步甲（异形步甲亚属）阿尔谢尼耶夫新种（A. (A.) arsenjevi sp. nov.）。后一个物种是根据滨海边疆区南部的几个地点描述的（模式产地：亚科夫列夫卡区阿尔谢尼耶夫卡河泛滥平原别尔佐沃村以南1公里处）；它在古北区物种中相当独特，在总体形态上与一些新北区物种最为相似，尤其是与异形步甲（异形步甲亚属）哈里斯亚种（A. (A.) harrisii LeConte, 1863）。异形步甲（异形步甲亚属）三齿亚种首次在俄罗斯被记录。指定了点翅异形步甲的选模。讨论了所有四个物种的分布和独特特征，并提供了鉴定它们的检索表；展示了它们的形态以及雄性和雌性生殖器。
