cdelphia's Identifications

When I first saw this I assumed B. nevadensis, but it just looks a little different from what I’m used to seeing in that species. The next closest I’m getting is B. morrisoni - out of documented range though in predicted climatic suitability (Williams et al. 2014).

Color is a richer yellow, top of head yellow, u-shaped yellow with black below on t3. Tried zooming in on face but can’t quite tell cheek length to width ratio or clypeus pitting to distinguish from nevadensis. Maybe a more discerning eye can.
