Lathrobium imminutum ASSING 2013

(Fig. 29, Map 1)

Material examined Japan: 1, 2, Honshu, Osaka-fu, Sakai, Yamato river, 25.IX.1934, leg. Yano (BMNH, cAss) ; 1, Osaka-fu, Yodogawa, 23.IX.1934, leg. Yano (BMNH) .

Comment: This species was originally described from the Chinese provinces Beijing and subsequently reported also from Heilongjiang (ASSING 2013b, c). The above specimens, two of which have type labels (" Neobisnius tenuis ", a manuscript name) by Cameron attached to them, represent the first records from Japan. The currently known distribution is illustrated in Map 1. The ventral process of the aedeagus (Fig. 29) is apically slightly more slender in the above male than in the two males seen from China, but since no additional distinguishing characters were observed, this difference is attributed to intra- rather than interspecific variation.
