Platambus binliui sp. nov. from Sichuan Province, China, is described and illustrated. It belongs to the P. sawadai species group sensu Nilsson (2000).

New records of members of the P. sawadai group from China are provided: Platambus micropunctatus Nilsson, 2003 (Guangdong), P. punctatipennis Brancucci, 1984 (Fujian, Guangdong, Guizhou, Jiangxi, Zhejiang), P. regulae Brancucci, 1991 (Yunnan), representing a new species for Chinese fauna, and P. wangi Brancucci, 2006 (Hubei). Habitus and median lobe photographs for all mentioned species are provided.
