Alevonota japonica ( CAMERON, 1933) ( Figs 5-13 )

M a t e r i a l e x a m i n e d Japan: 13, 2♀♀, Hokkaido, Nopporo Forest Park, 24.V. & 5.VI.2008, leg. Lackner (cAss).

C o m m e n t: This species was originally described and subsequently recorded only from Honshu ( ASSING 2002, CAMERON 1933). The above specimens from Hokkaido are somewhat darker in coloration than the material seen from Honshu, but otherwise no significant differences were observed. Interestingly, unlike other Alevonota species , A. japonica is characterized by a sexual dimorphism of the head. In the male, the head is transverse, approximately 1.1 times as wide as long, and the eyes are larger, approximately as long as the postocular region from the posterior margin of the eye to the posterior constriction of the head, and more bulging. For illustrations of the external and sexual characters of the material from Hokkaido see Figs 5-13 .
