Diagnosis.
This species is similar to Agrilus piliventris Deyrolle, 1864 in the transverse shape of the pronotum; the ventral and pleural abdominal regions completely covered by golden-yellow pubescence; the scutellum subrectangular with prominent carina; the scutellar disk and carina impressed; the scutellar projection enlarged; and the elytral apices spinose. Agrilus spineus can be distinguished from Agrilus piliventris and by the metallic black pronotum, greenish-black elytra with minute golden dorsal pubescence; and the elytral apical spines turned medially.
