Xantholinus longiventris

This keyed to longiventris but it's always reassuring when the genitalia match as well. This one came to light in my garden.

This one was swept from grass tussocks, rush and rhododendron saplings along a path in a birch woodland with rhododendron understory.

This one was swept at the same place a couple of years later.

These were in pitfall traps (in propylene glycol, so no live photos). I think all of these were female.
