【Abstract】 In this paper three new species of the genus Summits are described. Type specimens are deposited in the Institute of Zoology, Academia Sinica.Summits brunneus, gp. nov. (fig.1)Allied to S. yunnanus Mader, distinguished from the latter by its different body coloration and form of pronotum, and by the arcuate coxal line of the 1st abdominal sternum.Holotype , Lushui County, Yunnan, China; June 8, 1981, collected by Wang Shu-yong. Allotype , Sichuan (Mt. Emei, 800-1000m). Paratype 9, Sichuan (Mt. Emei, 800-1000m).Summits nigrofuscus, sp. nov. (fig. 2)This species resembles very closely S. brunneus, sp. nov., but differs from the latter in the small protuberance of the coxal line of the 1st abdominal sternum and in the female ge-nitalia.Holotype , Weixi County, Yunnan, China; July 21, 1981, collected by Wang Shu-yong.Sumnius petiolimaculatus, sp. nov. (fig. 3)Closely allied to S. cardoni Weise, distinguished principally by the body length, the ratio between the length of elytra and the length of petiolate mark on elytra, and the female genitalia.Holotype , Xishuangbanna, Yunnan, China; April 24, 1958, collected by Wang Shu-yong.更多还原
