ABSTRACT. Nine species of the genus Lesticus Dejean, 1828 from Vietnam are reviewed, including new four described: L. bellus sp.n., L. verticillatus sp.n., L. attenuatus sp.n., and L. laevis sp.n. New synonymy is established: L. p. praestans (Chaudoir, 1868), stat.n. = L. nigerrimus Straneo, 1953, syn.n., = L. tonkinensis Jedlička, 1962, syn.n. Lesticus mouhotii (Chaudoir, 1868) = L. fortis Tschitschйrine, 1897, syn.n., is downgraded to a subspecies of L. praestans. Lesticus buqueti (Laporte de Castelnau, 1834) = L. chalcothorax (Chaudoir, 1868), syn.n. = L. stephanschoedli Kirschenhofer, 2005, syn.n. = L. salvazai Dubault et al., 2012, syn.n. = L. kangeanensis Dubault et al., 2012, syn.n., is recognized to be a widespread and much described species. Lesticus lakhonus Tschitschйrine, 1900, stat.rest., is resurrected from synonymy of L. chalcothorax. Keys to species and three species groups, the auricollis-, the chalcothorax-, and the insignis-group, are provided.

KEY WORDS: Coleoptera, Carabidae, Pterostichini, new species, new synonymy, Vietnam.
