A revision of some Far Eastern Chlaenius species is presented. The following synonyms are proposed: Chlaenius circumductus A. Morawitz, 1862 = Chlaenius lineellus Motschulsky, 1859, syn. nov.; Chlaenius semipurpureus Motschulsky, 1865 = Chlaenius posticalis Motschulsky, 1854, syn. nov. Lectotypes of Chlaenius lineellus Motschulsky, 1859, Chlaenius semipurpureus Motschulsky, 1865 and Chlaenius hospes A. Morawitz, 1862, as well as the holotype of Chlaenius posticalis Motschulsky, 1854 are designated. Only one species of the subgenus Agostenus Fischer von Waldheim, 1829, viz. Chlaenius quadrisulcatus (Paykul, 1790), is shown to populate the Far Eastern islands of Sakhalin and Kunashir (Russia), and Hokkaido and Honshu (Japan), which is new to the fauna of the Kuril Archipelago.
