Diagnosis.

This species resembles Agrilus ascanius in having the elytra markedly tapering apically; the elytral apices spinose; the pronotum almost square, disk impressions and prehumeral, marginal and submarginal carinae almost identical; a large rectangular scutellum and pronounced triangular scutellar projection; the thorax and abdomen with golden yellow tomentose patterns; and the head obviously large, metallic in color, and eyes markedly protruding. Agrilus seramensis can be differentiated by the following characters: the pronotum is green (red in Agrilus ascanius ), the elytra are green-yellow basally turning blue apically; the scutellum posterior to scutellar carina and scute llar projection depressed; the entire scutellum black; ventrite 2 with lateral tomentose golden-yellow spots; the pronotal lateral margin straight (arcuate in Agrilus ascanius ); and a broader prosternal process.
