记述采自中国山东境内危害欧美杨的厚爪叶蜂属(膜翅目:叶蜂科:突瓣叶蜂亚科)一新种:中华厚爪叶蜂Stauronematus sinicus Liu,Li & Wei。本种与杨厚爪叶蜂S. platycerus ( Hartig,1840) (杨扁角叶蜂)近似,二者主要区别特征是:新种后足基节仅基缘黑色;中胸前侧片上部被毛稀疏,下半部具光裸区;锯腹片17节,3 - 12节缝具刺毛带; 1 - 5锯刃具细小亚基齿,6 - 17锯刃亚基齿变宽大;锯基腹索踵基角突出;阳茎瓣头叶中位刺突伸向背叶背顶角,腹叶腹缘稍内凹;体长4.5 ~ 6.0 mm等。此外,中华厚爪叶蜂与杨厚爪叶蜂、柳厚爪叶蜂的COⅠ序列K_2P距离分别为16.0%和15.7%。
