Identification
According to (1), "ventral surface of body not clothed by a dense tomentum that largely obscures the surface. Pronotum distinctly margined at least in part. Front angles of pronotum in side view are angled. Suture between abdominal sterna 1-2 obliterated or faint. Abdominal sterna 3-5 in females not distinctly clothed." However, italicized couplet refers to Squamodera, which is currently considered a subgenus of Acmaeodera.

Remarks
Some are pests of timber
Most beetles, including most buprestids, fly with their elytra held out and vibrating their hindwings to give lift and thrust. Acmaeodera, however, fly with their hind wings only — the elytra are fused down the center and form a shield over the insect's abdomen, even during flight. This fact, combined with the banding across the abdomen which is common (though not universal) in this genus, gives many of them a distinct wasp-like appearance when in flight.(6)
