Red and black oblong beetle?

[Grim Tuesday]

Picture attached. I believe this came in with a plant. Or maybe came from outside? I've never seen one before. I spotted it crawling around on the leaves today, but it doesn't look like it's doing a ton of damage. Should I be worried? My initial googling made me think it was a dendrobium beetle, Stethopachys formosa, but I don't have any orchids from Australia and the head color is wrong.
