clypeus, labrum, front basitarsus, vertex
Although the diagnostic features in females of this species are not as pronounced as in the male, they are nevertheless enough for a species ID (when taken in combination with colour patterning).
As in the male:the clypeus is broad with a median carina basally (star); the labrum is depressed basally (dotted arrow); and the front basitarsi are expanded (solid arrows) as are the following tarsomeres.
Note too the vertex level with the eye tops (line). This is the not an uncommon condition, but it does contrast with some other extensively yellow species such as B. flavifrons.
Finally, in this species the female typically has a pair of black spots on the yellow clypeus. This too is a widespread pattern, seen in many species (yet often highly variable within a species).
