Two new species of the genus Scaphidium Olivier from Xizang (Tibet Autonomous Region), China are described: 1) S. rhopaliparamerosum sp. nov. [棒侧叶出尾蕈甲], distinguished by four dark red big fasciae on apical 1/3 and basal 1/3 parts of elytra; and 2) S. russipenne sp. nov. [绛鞘出尾蕈甲], distinguished by the unified brownish red colour on elytra. For both new species, we provide descriptions and colour plates of normal light photos for the diagnostic characters: habitus in both dorsal and ventral views, an antenna, a prefemur, and the detailed structures of the aedeagus (if male available). Additionally, a new spot pattern of S. formosanum Pic is reported from Yunnan.
