Abstract
Species of the genus Thoracostrongylus Bernhauer, 1915 occurring in China are reviewed. Four new species and one new subspecies are described: T.baishanzuensis sp. nov. (Zhejiang), T.bicolor sp. nov. (Guangdong, Guangxi, Hunan, Yunnan), T.brachypterus sp. nov. (Sichuan), T.chrysites sp. nov. (Fujian), and T.formosanusflavipes ssp. nov. (Zhejiang, Fujian, Hubei, Hunan, Sichuan, Guangxi, Guangdong, Anhui, Jiangxi). A new synonymy is proposed: T.baoxingensis Yang, Zhou & Schillhammer, 2011 syn. nov. is in fact T.acerosus Yang, Zhou & Schillhammer, 2011. New provincial records for T.acerosus Yang, Zhou & Schillhammer, 2011 are reported. A key to Chinese species of the genus is provided.
