The new species, Arachnospila (Ammosphex) altaica Loktionov, sp. nov., is described and illustrated from the Altai Republic, Western Siberia, Russia based on male specimens. The new species belongs to A. (Am.) abnormis species-group, whose males have a tuft of long bristles on hypopygium ventrally. The male of the new species is clearly distinguished from congeners by the unique shape of the hypopygium and the position of the bristles on it. Seven species of the subgenus Ammosphex Wilcke, 1942 from the genus Arachnospila Kincaid, 1900 are newly recorded from Western Siberia. The new species and new regional records raise the number of species known from Western Siberia to 58, and the total number of spider wasps in Russia to 251.
基于雄性标本，对采自俄罗斯西西伯利亚阿尔泰共和国的新物种——阿尔泰蛛蜂（蛛形细腹蛛蜂亚属）进行了描述和图示。该新物种属于异常蛛蜂物种组，其雄性腹部腹板有一簇长刚毛。新物种的雄性通过独特的腹部腹板形状及其上刚毛的位置与同属其他物种明显区分开来。首次记录了采自西西伯利亚的、来自1900年金凯德蛛蜂属（Kincaid）的1942年威尔克细腹蛛蜂亚属（Ammosphex Wilcke）的7个物种。新物种和新的区域记录使西西伯利亚已知的物种数量增加到58种，俄罗斯蛛蜂的总数增加到251种。
