Remarks. The species has been originally described from the Iturup Island (S Kuriles) and known also from N Japan ( Watanabe & Shibata 1965: Rishiri Island near Hokkaido; Tichomirova 1973) and the Sakhalin Island ( Molodova 1973). Jakobson (1909) had mistakenly cited it under the name contractum used a bit later by Schubert (1911) for another species. Filatova & Lafer (1978) did not report L. japonicum from Iturup but it is quite evident from the material above, that all their records of L. brunnipes are to be referred to the former species. I suppose L. japonicum kunashiriense Y.Watanabe to be a synonym of L. japonicum owing to the perfect coincidence in terra typica (the statement by Watanabe 2006 that ‘the accurate type locality of Lathrobium (s. str.) japonicum wasn’t described in Bernhauer’s original account’ is not correct).
