Hi Gunnar

That is really helpful

I have a copy of the Withers, P. 1989 and this seems OK for what it is. Peter Chanler said he would provide me with the test keys of a document that is intended to replce this in time.

Do you know if any of the other refernce are available as PDFs?

I am having problems with setting the specimens in Euparal and getting too much shrinkage as it dries. and it's very hit and miss as to whether the genitalia end up in a useable possition when dry.
