Belongs within: Buprestidae.
The Chrysochroinae are a group of jewel beetles whose antennae have pores distributed over both surfaces of the segments rather than being concentrated into a ventral depression. The scutellum is tiny or absent. In members of the tribe Epistomentini, the fronto-clypeus is reduced or excised between the antennal insertions, exposing part of the membranous ante-clypeus.
