Lathrobium imminutum ASSING 2013 ( Fig. 29 , Map 1 )

M a t e r i a l e x a m i n e d Japan: 13, 2♀♀, Honshu , Osaka-fu , Sakai, Yamato river, 25.IX.1934, leg. Yano ( BMNH, cAss) ; 1♀, Osaka-fu , Yodogawa, 23.IX.1934, leg. Yano ( BMNH) .

C o m m e n t: 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.
