Abstract: A new species of the goliathine genus Bietia Fairmaire, 1898, B. naxiorum sp. nov., is described from the mountains in northwestern Yunnan (China). It is compared with two other species of the genus known so far, B. rudicollis Fairmaire, 1898 and B. simillima Fairmaire, 1898. The folloving new synonymy is proposed: Bietia rudicollis Fairmaire, 1898 = Atropinota funkei Heller, 1923, syn. nov. A lectotype is designated for A. funkei. Dorsal habitus and diagnostic characters on the male external genitalia of all three species of Bietia are illustrated. A diagnosis of the genus and a key to species are provided. The systematic position of Bietia among the known genera of the Oriental and Palaearctic Goliathini is shortly discussed. A brief description of the habitat of B. naxiorum sp. nov. as well as notes on its ground-dwelling habits are given; a ground-dwelling behaviour of adults is recorded for the first time in the Asian Goliathini.
