Key to species of Agrilus purpurifrons   species-group

Agrilus extrarmatus Curletti, 2003   (see Fig. 14 in Curletti, 2003) is not included in the key, but it is tentatively assigned to this group until the male is available. The type was not studied but its published image displays a transverse pronotum and spinate elytral apices which indicate affinity to this species-group despite the vertex being wider and frons lacking a distinct medial impression.
