Solitary wasp with 3 submarginal forewing cells and black and red body. Fore-tibiae blackish and 4th segment of hind tarsi not broader than long.
No interactions present.
I'm sure this is not Tachysphex pompliformis. The terminal colour of the wings is wrong, also the specimen has a stigma (lacking in TP). The rear face of the thorax is heavily granular, Tachysphex is muck more subtle.
It's also very hairy for Tachysphex?
I ran it through Yeo and Corbet too, and on the basis that it has a dark stigma, I agree a species of Astata.

Thanks for your comments... this is exactly the sort of thing iSpot is great for... I'll have another look at the book, and at Astata. A quick Google shows wasps with the same colouration as my specimen. The poor thing is starting to disintegrate but I'll try and get some more info so we can hopefully decide on a species...
I've added details from the photos showing the stigma and the pygidium (last dorsal plate). The key couplet is "Forewings with stigma indistinct, scarcely wider than the adjoining viens -> Tachysphex; or Forewings with distinct stigma, much wider than adjoining veins; hindwings about as wide as forewings -> Astata" Having rethought this I agree that Astata seems a better fit than Tachsphex. I just measured it as 10 mm long; the pygidium is dull and not lined with spines as far as I can see, so of the 2 Astata species in the book, I think this is probably A boops.
The pygidium IS lined with spines, quite clear along the lower edge in the image - which does make it A. boops.
Great stuff Steve... a combination of not correctly interpreting the image and not reading the key properly led me to the right ID! Thanks for your help.
