摘　　要：A new species of the Macrophya sibirica group, Macrophya harbina Li, Liu Wei sp. nov. from China is described. This new species is similar to M. revertana Wei, 1998, but differs from the latter in the posterior margin of pronotum and center of mesoscutellum white; postocellar area 1.5 times broader than long;mesepisternum not entirely black, center of posterior margin with a small white macula; mesepisternum minutely and densely punctured, not coarse, interspaces between punctures distinct; dorsum of mesoscutellum without carina, with very sparse and shallow punctures; hind femur largely black, base with white macula on dorsal side; posterior margin of abdominal tergum 1 with distinct white maculae; middle serrulae of lancet each with 2 proximal and 9–11 distal teeth. A key to all known species of the Macrophya sibirica group from China is provided.记述采自中国钩瓣叶蜂属Macrophya Dahlbom直脉钩瓣叶蜂种团M.sibirica group 1新种：哈尔滨钩瓣叶蜂Macrophya harbina Li,Liu＆Wei sp.nov.;简要讨论了M.sibirica group的主要鉴别特征,编制了M.sibirica group中国已知种类检索表。该新种与中国分布的反刻钩瓣叶蜂M.revertana Wei,1998十分近似,但新种前胸背板后缘、中胸小盾片大部白色;单眼后区宽长比约为1.5;中胸前侧片不完全黑色,后缘中央具小型白斑;中胸前侧片刻点较细小密集,不粗糙,刻点间光滑间隙明显;中胸小盾片无脊,刻点十分稀疏细弱;后足股节大部黑色,背侧末端具小型白斑;腹部第1背板中央后缘横白斑显著;中部锯刃齿式为2/9~11等特征,与后者不同。
