A new nitidulid

This beetle came to light a couple of weeks ago. At 6.7mm it's a bit of a beast of a nitidulid. 

 

It keyed easily to Soronia, of which there are only two species in the UK, punctatissima and the more often encountered grisea. 

Looking at the external characters was a bit confusing. The coloring led me towards grisea but the more evenly rounded sides of the pronotum made me think punctatissima.

Luckily it was a male so a quick look at its tackle and ....

...it's punctatissima. New genus, new species 👍
