Stenus clavicornis
This was found by suction sampling. I keyed it using Lott & Anderson and got it to clavicornis before examining the genitalia. Then I checked the aedegaus and fortunately that matched my ID.

This was also found by suction sampling. I assume it was a female as there was no aedeagus (although I couldn't find the spermatheca either).
