Comments. Laccobius inopinus is widely distributed from the Russian Far East and Japan to southern China. New for Jiangxi province. Among Chinese species, Laccobius inopinus is similar to L. bedeli Sharp, 1884 by the general habitus and morphology of the aedeagus, but may be distinguished from the latter by the combination of the following characters: (1) subapical widening of the median lobe is rather narrow but long (the widening is broad but short in L. bedeli ); (2) apex of median lobe is rounded (in contrast to acute apex in L. bedeli ). (3) paramere very narrow with large backward directed toot apically (parameres are wider and with very reduced apical tooth in L. bedeli ). The aedeagus of the Chinese L. inopinus is illustrated in Fig. 18 .
