unidentified beetle

Observation - unidentified beetle - UK and Ireland. Description: Around 4 mm long, and found on Broom in a large park. I'm not even sure of the family... there are several vaguely similar things on the web (e.g. Byturus), but not found anything that matches the pronotal outline and antennae.
