All type specimens are deposited in the Entomological Museum, Northwestern Agricultural University, Yangling, Shaanxi, China. 1. Nondenticentrus qinlingensis Yuan et Zhang, sp. nov.(Fig. 1) This new species is allied to N. curvispineus Yuan et Cui, but can be distinguished from the latter by: suprahumeral horns longer and slender, 1.5 times longer than the width between their bases; tip of posterior process curved downwards; height of metopidium longer than its width. Holotype♀, Qinling Mountains, Shaanxi Prov., 5~7-VIII-1962, coll. Yang Jikun. Paratypes 2♀♀, same data as Holotype; 1♀, Huashan Mountain, Shaanxi Prov., 21-VIII-1962, coll. Yang Jikun. 2. Nondenticentrus lingicornis Yuan et Zhang, sp. nov. (Fig. 2) This new species resembles N. albimaculosus Yuan et Cui, but differs from the latter in: suprahumeral horns slightly erected, their tips sharper, 3 times longer than the width between their bases; base of posterior process obviously projected, its tip curved downwards; height of metopidium equivalent to its width; with carina above ocelli. Holotype ♀, Gaolou Mountain (1700m), Wen Xian, Gansu Prov. 7-VIII-1960, coll. Yang Jikun. 3. Nondenticentrus aureus Yuan et Zhang, sp. nov. (Fig. 3) This new species is related to N. angustimembranosus Yuan et cui, but can be seperated from the latter in: head black; suprahumeral horns slender, more erected, 1.5 times longer than the width between theri bases; width of metopidium equivalent to its height; basal angles of scutellum with white specks. Holotype ♀, Taibei Mountain, Shaanxi Prov., 18-VII-1990, coll. Wang Yinglun. Paratypes :2♀♀, same data as holotype; 1♀, Huangang Mountain, 21-VII-1983, coll. Huang Jian. 4. Nondenticentrus fulgipunctatus Yuan et Zhang, sp. nov. (Fig. 4) This new species resembles N. zhongdianensis Yuan et Cui, but is different from the latter in the following characters: body robust; suprahumeral horn is shorter and broader, almost erected, extending upwards, outwards and backwards, its length slightly shorter than the width between their bases; posterior process shorter, not reaching inner angles of tegmina, upper carina obvious, its tip black; centre of tegmina with obvious white specks.
