Diagnosis. This species (Fig. 32), together with A. mirei (Fig. 33), is characteristic by the obsolete elytral pubescence in comparison with other members of A. muscarius species-group. Agrilus kurumi may be distinguished from A. mirei by the flat pronotum with the less arcuate sides.

Length. 4.1–5.0 mm.

Variability. Specimens vary in body shape (robust–elongate), color of elytra (combination of blackish with gold or green patterns), prosternal lobe (arcuately emarginate or incised) and sides of prosternal process (expanded arcuately or rectinlinearly).
