Abstract. Three new species of genus Chlaenius Bonelli subgenus Lithochlaenius Kryzhanovskij are described from China: Chlaenius chuanqianensis Liu & Liang, sp. n. (type locality: Xishui, Guizhou Province), Chlaenius linwensini Liu & Liang, sp. n. (type locality: Fujian Province), and Chlaenius propeagilis Liu & Kavanaugh, sp. n. (type locality: Gaoligongshan, Yunnan Province). Seven species of the subgenus are redescribed: Chlaenius agiloides Jedlička, Chlaenius formosensis Lorenz, Chlaenius agilis Chaudoir, Chlaenius leishanensis Kirschenhofer, Chlaenius noguchii Bates, Chlaenius rambouseki Lutshnik, and Chlaenius wrasei Kirschenhofer. Additional taxonomic changes include the following: Chlaenius formosanus Jedlička is treated as a junior synonym of Chlaenius rambouseki Lutshnik and Chlaenius anchomenoides Bates, syn. n. and Chlaenius nuristanus Jedlička as junior synonyms of Chlaenius agilis Chaudoir, syn. n. Chlaenius latroLaFerté-Sénectère is considered a nomen nudum stat. n. and unavailable, leaving Chlaenius agilisChaudoir as the next available name. Chlaenius nuristanusaberration rubridipesJedlička is also an unavailable name. Chlaenius formosensisLorenz (=Chlaenius formosanusHabu) is returned to species status stat. n. A key to adults of the 10 known species of subgenus Lithochlaenius is provided.
