Has the British subspecies (Arvicola terrestris ssp. amphibious) been speciated from the European subspecies now?
Record your ladybird sightings!
Yes, when I searched the British water vole it was amphibius. But I did some further research and IUCN say this;
Strictly speaking the British water vole has not been split from European water voles; rather it is just a taxonomic name change. Linnaeus, probably on one of his off days, gave the water vole two names A. terrestris and A. amphibius. Presumably this was a mistake.
In 1857 Blasius was the first person to re-visit Linnaeus' work on water voles and he chose to call them A. amphibius, therefore, by the rules of taxonomy A.terrestris, like the brontosaurus (now apatosaurus for the same reason), no longer should be used - its a taxonomist thing!
However, there has been a split in that the sub-species, formally known as, A. terrestris scherman, found in France and Germany, is now a separate species, as is A. sapidus found in France and Spain.
Confused? Just look at the taxonomy of baboons, its enough to make you wish Linnaeus had not fathered the science of taxonomy!

Thanks for clearing that up. Is there a taxonomic difference between the brown water voles in the South and black water voles in the North?
The north / south divide again - even water voles suffer from it!
No, no difference, just a genetic colour variation as far as I know.
No wonder I was confused trying to look it up! Cheers for clearing that up - sounds like it should be filed with the geranium/pelargonium debate!
