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. Tim tim worfolk attached the following image:  [160.69Kb] |

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.
