Hi Colin

I'm not certain, but I think the old website has now been closed. Information about references to families is available on this site. Go to Resources/DF Membership Area/Keys - description of families. You will find the references listed under "Identification" at the foot of each family account. But you will have to manually scroll to the list of references to see what they are - perhaps hyperlinking is not top priority at the moment. 

It looks like a well-marked Epistrophe eligans to me Anthony. Does it key out in that direction?

I guess that's right - it falls closest to the 'exceptionally yellow' variant in Stubbs and Falk.  I think the bluntness of the markings on tergite 2 had me wandering towards key 22b.  Thanks Martin.
