ABSTRACT. The subgenus Haplochlaenius Lutshnik, 1933 of the genus Chlaenius Bonelli, 1810, is re-assessed to be interpreted in a wide sense, with Haplochlaenius sensu Azadbakhsh et Kirschenhofer, 2019, considered as corresponding to the costiger-group only and Sphodromimus Casale, 1984, syn.n., divided into two species groups, complemented at the moment by some ungrouped species. Twelve species recorded in Vietnam are reviewed and keyed, including new seven described: Ch. bicoloripes sp.n., Ch. capitatus sp.n., Ch. costulipennis sp.n., Ch. fuscipes sp.n., Ch. opacus sp.n., Ch. planicollis sp.n., and Ch. silvestris sp.n. Besides, the name Ch. pseudopilosus sp.n. is proposed for the species from Yunnan, China, misidentified [Qin et al., 2022] as Ch. pilosus (Casale, 1984). Chlaenius tamdaoensis Kirschenhofer, 2003, stat.rest., is resurrected from synonymy of Ch. enleensis Mandl, 1992. Also, new synonymy Ch. peterseni (Louwerens, 1967) = Ch. dacatrai Kirschenhofer, 2023, syn.n., is established.
KEY WORDS: Coleoptera, Carabidae, Chlaenius, Haplochlaenius, new species, new synonymy, Vietnam, Oriental region.
