Diagnosis.

Agrilus pluvius sp. n. is very distinctive by the large size and it differs from all members of the subgroup by having the apical half of elytra more elongate; by the arcuate apical margin of pygidium and by the distinctly sinuate sternal groove on the apex of last ventrite. See also Appendix.
