Thanks Stephane. One of the rare occasions for me when one of these keys readily. No doubt the next specimen will be back to the drawing board!

Helina quadrum
Tibia 1 yellow – looks ok from the photo
Are there spots on tergites 3 and 4?, a shot of the abdomen would be really good for the gallery :)
I agree with Stephane on the ID

Hello Elisabeth
T1 coloured as T2 + T3
Abdomden greasy so appearance is misleading. Suspect unspotted? But quite impossible to be sure.
