Seems to key out as
Macquartia tenebricosa, can anyone confirm or correct?

Was it really small? How about
Dufouria? I am finding them all over the place recently :) The sloping head is quite distinctive.

Certainly small if it was a
Macquartia, I see what you mean about
Dufouria though, looks good. Here's another shot - poor quality though.

Well,
Macquartia &
Dufouria are very close in the key and share the '3 scutellar bristles' feature. I haven't keyed any of mine yet but they look pretty identical to yours and I am calling mine
Dufouria for now ... the only sticky bit is *which*
Dufouria ... and there it gets more difficult but
D.chalybeata is the commonest around here ;)

Tergite 2 appears to have a row of marginal bristles so must be
Dufouria. As to which one; well mid tibia has at least 3 ad, there's a row of bristles on tergite 2, fore tibia seems to have 2 posterior bristles, costal spine doesn't appear to be shorter than r-m - all in all I'd the evidence points to
chalybeata.
