Diadasia bituberculata

Diadasia
. Correct or not?

I did see
what may be facial fovea, and was thinking about
Andrena
, but wasn't sure. Also thought about what looks more like a flatter, rather than convex vertex (though that's better seen from the front), which (if so) would also steer toward something non-
