Remarks. By far the most common Far Eastern species of the ‘large’ Lathrobium (s.str.), probably confused frequently by previous authors with L. castaneipenne Kolenati, 1846 or L. geminum (see above). Described from the Maritime Province (Vladivostok, Ussuriysk), reported also from S Sakhalin (Molodova l.c.). The new record for Zeyskiy Nature Reserve is the utmost northwestern find of the species.
