Questions about Coelioxys texanus

I just  wanted a confirmation of the identification of the male bee below as a Coelioxys texanus.   The pedicels and scapes of the bee are black rather than red.   Farther below are examples of other Coelioxys texanus you identified for us -- these have the usual red pedicels and scapes.  The following information is listed in the Discover Life Database page for Coelioxys texanus:   "In both sexes of Coelioxys texana the antennal scape and pedicel are usually ferruginous, a condition found in no other North American Coelioxys spp."

Female bee

This is a large female bee - 14 mm -- found feeding on goldenrod, about ten

yards from the bush where the male Coelioxys shown above appeared two days earlier.  As with the male bee, the scapes and pedicels of this female bee are red.

The tip of S6 is blunt -- this is why I think this is C. texanus instead of C. hunteri?

The bee also has a tuft of white hair in front of the central ocellus.  Matted hairs obscure most of the bee's jaws, also a trait of C. texanus.
