I agree it is A. asserta. Can't see the lower abdominal hair bands clearly, but A. asserta also has a yellow mark on the scape (first antennae segment) which can just be seen in your photo. Don't know why it doesn't come up in the potential species list - I'll look into it.
Thanks for the extra photo, Leigh. I contacted the administrators - new species need to be added via the 'Add species' box on the species page. I've added A. asserta.
