Found this one yesterday in Somerset, UK and keyed it to Potamia littorlalis. Appears rather uncommon or under-recorded so thought I'd post for a second opinion/correction. Thanks.

Submedian pv on f3; long setae on fore coxa; upward-directed seta on anterior gena - everything present = Potamia littoralis, yes.
