Type specimens are deposited in the Museum of Hebei University （MHBU）. 1. Agnaptoria nigriceps, sp. nov. （Figs. 1-13, 24-25） The new species can be distinguished from other species of Agnaptoria by only inner surface of protibiae densely covered with pale hairs at apex. It is closely related to A. markama Shi et Ren, but it＇s pronotal disc without pit; pro- and mesotibiae gradually widening toward apex; only mesotarsomere 1 covered with hair brush. Etymology： The specific name refers to black head. Holotype： ~, Zayu, Xizang Autonomous Region, 28°31＇ N, 98°09＇ E, 4 200- 4 300 m, 05-Ⅶ-2005, collected by SHI Ai-min （MHBU）; Paratypes： 29 ♂♂ and 20 ♀ ♀, same data as the holotype （MHBU）. 2. Agnaptoria apicopilosa, sp. nov. （Figs. 14-23, 26） The new species is close to A. nigriceps, sp. nov., but can be distinguished from the latter by anterior margin of clypeus straight; antennae long, apical 3 antennomeres extending beyond pronotal base; anterior margin of pronotum bordered along entire length; elytral surface sparsely covered with dark punctures; mesotarsomeres 1 and 2 covered with hair brushes. Etymology： The specific name refers to only inner surface of protibiae densely covered with pale hairs at apex. Holotype：♂, Zayu, Xizang Autonomous Region, 28°32＇ N, 98°02＇ E, 3 400 m, 06-Ⅶ-2005, collected by SHI Ai-min （MHBU）.
