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!

Hello Finlay, Indeed a Themira. Looks like Themira minor/lucida. You can find a key to Themira species here: https://www.resea..._of_Europe Kind regards, Ectemnius |

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. https://www.resea...a_Sepsidae Kind regards, Ectemnius |
