Thanks Frans
The id to genus is a lot better than what I had it at:-)

Isotomurus sp.
At first I thought it was Hydroisotoma schaefferi, but the long tapering dentes match with the related genus Isotomurus.
I cannot see the macrosetae at the terminal body segments. And the dorsal pigment pattern is not distinct enough to do a further ID.
