Two new species of the genus Pristaulacus, P. ohishii sp. nov. and P. uenoi sp. nov. are described from Japan. The former species belongs to the comptipennis species group in having the strongly concaved occipital margin, and is peculiar in the species group in having the combination of the interrupted occipital carina and a broadly rounded and shallow occipital medial groove. The latter species resembles P. ryukyuensis in having the occipital carina not interrupted, the anterior margin of mesoscutum in lateral view acute and veins M+Cu, r-m and Cu of hind wing not pigmented, but they can be easily distinguished by the coloration of mesosoma and the dark spots of fore wing.
从日本描述了锯角叶蜂属（Pristaulacus）的两个新物种，即大桧锯角叶蜂（P. ohishii sp. nov.）和上野锯角叶蜂（P. uenoi sp. nov.）。前一个物种属于具强烈凹陷后头缘的细翅锯角叶蜂物种组，并且在该物种组中很独特，具有间断的后头脊和宽圆形且浅的后头中沟的组合。后一个物种在具不间断的后头脊、中胸盾片前缘在侧面观尖锐以及后翅的M+Cu脉、r-m脉和Cu脉无色素沉着方面类似于琉球锯角叶蜂，但它们可以通过中体的颜色和前翅的黑斑很容易地区分开来。
