Diagnosis. Agrilus asahinai is similar to A. bidentulus in the shape of the prosternal lobe (Fig. 28), but it differs from it by the denticulate sides of the median lobe of the aedeagus (Fig. 14) and the sharply protruding metacoxal plates (Fig. 38).
Distribution. China (Hebei, Heilongjiang (Alexeev 1979)); Japan (Honshu); Korea North; Korea South; Russia (Primorsky Kray, Sakhalin).
Biology. Alexeev (1979, 1989) cited Lonicera maackii as the host plant for A. asahinai.
