Two rugosochonetid species, Neochonetes (Huangichonetes) geniculatus sp. nov. and Neochonetes (Zhongyingia) linshuiensis sp. nov., are described from the Lopingian (Late Permian) of the Chuanmu section, Sichuan, South China. Ecological changes from the diverse upper Changhsingian brachiopod palaeocommunity to the depauperate post-extinction brachiopod community are briefly discussed. © 2005 Association of Australasian Palaeontologists.
