|Another small brownish leaf beetle!|
|Tibial dent with fringing hairs|
This dent means that the beetle is in the genus Chaetocnema - it looks like the fringed dent could be used for cleaning another appendage but I must confess I don't know what its function is and I can't find it mentioned in any of the literature I have or via a fairly quick web-search; if anyone knows, please do post a comment here! Anyhow, moving onto species-level identification, the head needs to be looked at closely to see if there is a keel running across between the antennae. In this case there isn't, but there are several punctures above each eye which I've tried to photograph - it was tricky and the clearest image is here with a puncture indicated by the arrow.
