Hi, really struggling to ID this Sepsid or find an appropriate key. Possibly Themira but I'm not sure. Found it in some grassland/maintained meadow next to a small lake in Central Scotland. Measures 3.4mm from the bottom of the abdomen to the top of the thorax.
Anyone know what it might be? I can take more pictures of particular features if they would be helpful/diagnostic.
Thanks! :)

I'd be very interested, but there is no picture visible...

Hello Finlay,
Indeed a Themira. Looks like Themira minor/lucida. You can find a key to Themira species here:

Hi Ectemnius,
Amazing, thank you so much! How can you tell it's a Themira so definitively?
Thanks,
Finlay

Hi Finaly,
Well, it's an entirely black Sepsidae with no wing spot. That coupled with the habitus and the typical armature of the front legs' tibia and femur.
After collecting about a thousand specimens in the Netherlands and publishing four species new for the fauna I can say, no other North-Western European Sepsidae have such a habitus.
