Evagetes crassicornis

This landed on my car in the middle of an ex-arable field that's being restored to heathland.

I used Mike Hackston's key to get it to genus which was very straightforward. My only hesitation was at the last couplet which required a view of the mandibles. These were firmly closed and although I could nevertheless see just a single tooth I wasn't entirely sure if I would be able to see additional teeth without prising the mandible open (or off). Eventully I decided to do so and this enabled me to confirm that there was only a single clearly-defined tooth (although there was a tiny bump between this and the apex of the mandible). I then used the RES key which Hackston's key is based on to get it to species. This was less easy as I struggled to orientate it correctly to see the "comb" of spines on the hind basitarsus, and therefore difficult to work out which of the various spines and bristles belonged to the comb. It's forewing was 4.1mm long.
