Nice observation of a male Pyractomena! This could be Pyractomena lucifera or Pyractomena marginalis, but hard to say without flash pattern details and a dissection of genitalia. The pronotum doesn’t look as elongated or rounded as it does in typical Pyr. lucifera, so if I had to guess I’d say Pyr. marginalis.
