I recently contacted Tommy
about this specimen.


Here was his response: "The shot of the side of the elytron is key. B. striolatum has the punctures aligned arranged in rows, where in B. ephippigerum the punctures are sub-confluent, forming a mesh-like pattern. Typically B. ephippigerum is also multi-colored, while B. striolatum is unicolorous, typically dark reddish brown."
