Aedeagus (Fig. 29): Symmetry: symmetric, Shape: widest in basal part, Modifications: apex of medial lobe sharply pointed.
Diagnosis
From the very similar Agrilus pseudoambiguus sp. n., it differs by having the pronotum more elongate with sides almost straight; by having an obvious pronotal lobe and by the elytral apices being distinctly denticulate. See also Appendix.
Type locality
Thailand, Sakon Nakhon province, Phu Phane National Park, 17°07'30"N, 104°01'E, altitude 350 m.
Type material
Holotype (Fig. 9), ♂, (EJCB): “Thai, Sakon Nakhon, Phu Phane Nat.Park, 17°07'30"N, 104°01'E, 350m, ix.2000, local collector”.
