The present paper deals with four new species of the genus Anteon Jurine from China. All the type specimens are deposited in Zhejiang University. 1. Anteon planum, sp. nov. (Figs. 1,2) This new species is very similar to Anteon lankanum Olmi, but differs from the latter mainly in: 1) segment 4 of front tarsus longer than segment 1; 2) segment 5 with inner side convex. Holotype ♀, Mt. Tianmu, Zhejian Province, 2～4-Ⅵ-1990, by Shi Zuhua, No. 902474. 2. Anteon transverum, sp. nov. (Figs. 3,4) This new species is related to Anteon fidum Olmi, 1989, but differs from the latter mainly in: 1) segment 4 of front tarsus two times as long as segment 1; 2) posterior surface of propodeum with transversal keels, without reticulate rugose; 3) head and prothorax not fully black. Holotype ♀, Jinding, Mt. Fanjing, Guizhou Province, 12-Ⅶ-1993, by Yao Songlin, No. 930727. 3. Anteon serratum, sp. nov. (Fig. 5) This new species is allied to Anteon javanum Olmi, 1984, but differs from the latter mainly in: 1) pronotum and mesothorax black; 2) the inner side of enlarged claw with 2 rows of teeth. Holotype ♀, Mt. Longwang, Zhejiang Province, 31-Ⅷ-1993, by He Junhua, No. 9310660. 4. Anteon convexum, sp. nov. (Fig. 6) This new species is similar to Anteon pectinarolium Xu et He, 1996, but differs from the latter mainly in: 1) head with one strong keel connecting posterior ocelli to occipital carina; 2) head with POL∶OPL∶TL=4.5∶3.6∶2.8; 3) apical region of segment 5 with one inner side convex. Holotype ♀, Mt. Changbai, Jilin Province, 10-Ⅷ-1977, by He Junhua, No. 771483.
