Neatly done Chris.
Useful stuff here.
http://www.coleoptera.org.uk/species/chrysolina-banksi - where the picture is poor
Metallic bronze, no metallic reflection?, less 'hammering' on elytra
Could leg to body contrasts (colours) be useful?

Chrysolina staphylea/banksi

Thanks Chris. I had forgotten about this. Yes, I subsequently i/d this and others found later here as banksi.

The new Chrysomelid book was a bit disappointing on these, repeating the old key description of the puncturation which I found imprecise. In fact the puncturation of these two - according to photos on the internet - seems totally distinct. The description refers to lines of puncturation in staphylaea but random scatter in banksi. But if you look at my shot, there are definite lines on either side of the mid-line (and in other individuals the lines are even more obvious), so this left me puzzled.

In fact staphylaea has much smaller, close-set puncturation in obvious 'lines', with the distance between adjacent ones front and back much less than on each side. This isn't clear either, I know, but with a bit of effort it shoudn;t be too hard to come up with the right wording.

C. staphylaea is also rather duller and browner, but I am not sure how obvious this is in the field.

Thanks for reminding me about this! I haven't actually looked at the guide before writing this, so may be mis-remembering.
