Descriptive notes.

Male (Fig. 3D). Antennae (Fig. 5D) flabellate, overlapping half-length of elytra when inclined. Antennomere II transverse; III-XI lamellate, antennomere III with lamella nearly as long as joint itself, and lamella of IX longest, 3.2 times longer than joint itself. - Aedeagus: median lobe moderately curved near middle in lateral view, at an angle of ca. 150° between basal and apical parts of dorsal side, moderately arcuate at base part, subapical part slightly inflated dorsally (Figs 7C, 8A); moderately curved at basal part in ventral view, subapical part moderately inflated laterally (Figs 7B, 8B), with a fusiform ventral cavity (Fig. 7B); apical part gradually narrowed distad (Fig. 7A, B, D), with a deep V-shaped notch at apex (Fig. 7A, D).

Remark.

In terms of the special structure at the apex of the median lobe (Fig. 7D, E), we suggest placing this species into the M. dotatus species group.

Distribution.

China (Jilin, Heilongjiang, Liaoning), Japan, South Korea, Russia.
