Material of the paederine genus Lathrobium Gravenhorst, 1802 from the Nanling National Nature Reserve, southern China, is examined. Four species are identified, one of them described previously. Three species are described and illustrated for the first time, all of them micropterous and locally endemic: L. yangyihani Lin & Peng sp. nov., L. jiaxingyangi Lin & Peng sp. nov., and L. wangxingmini Lin & Peng sp. nov. The female sexual characters of L. guangdongense Peng & Li, 2014 are described and illustrated for the first time.
