Bembidion mannerheimii is very close to Bembidion guttula. Closer, in fact, than traditional keys suggest, with recent publication indicating whether a specimen is winged or not is not 100% surefire way to separate the two - including in the same locations. This, from yesterday, I am taking to be mannerheimii until I can find the relevant article. It has two things which are separating it from B.guttula.
A new one for Cullaloe, but not for me.

On finding the Coleopterist article it seems that short-winged guttula nevertheless does still have more wing. I'm still happy with this as mannerheimii
