This bee is a male Agapostemon found feeding on wild sunflowers, in an arid habitat, near the Mexican border. Is this Agapostemon texanus?

The bee has yellow-and-black stripes on its abdomen, and a bronze-green metallic sheen on its head and thorax.

The bee also has well-defined black markings on the inner sides of its back legs. Its hind femurs have black marks on both the top and bottom joints, on the sides facing the bee. Each hind tibia has a continuous stripe from one joint to the other, on the sides facing the bee.

The Discover life database notes that male A. texanaus and A. angelicus can be distinguished by this trait: “A. angelicus - Hind tibia with black to brown markings on the surface facing the abdomen and never markings on the opposite surface 1A. texanus - Hind tibia with black to brown markings on both surfaces.”

This bee, as shown in the photos has brown markings on both surfaces. So, can we assume this is A. texanus?

Any help you can provide would be much appreciated.
