These are images of a male Chimney Bee in a Lance-leaf Globe Mallow flower. His wing patterns seem to be a close match to those of the Diadasia Coquillettapis
subgenus grouping. Furthermore, after comparing his abdominal tip to the larger-sized male bees of that grouping, like those on the males of D. bituberculata
, I can see that they are almost the same exact shape proportionally, though very different in coloration. (much, much lighter, with two darkened tips)
This bee appears to be very similar to many of the smaller sized and shorter haired male bees in the Mallow-visiting group of subgenus Coquilletapis
. Many of those bees are most likely D. dininuta
and yet some other types of Chimney Bees seem to be placed in there with them. I hope that someone can sort things out very soon and I will try to help.
The USDA Forest Service lists D. diminuta
as a Globe Mallow Bee
for it's common name, due to the observed associations, seeming to be exclusively with that plant, but they don't yet have much ID information on the website that could help us with the placement of our images. Please note that many other types of bees may also visit this plant. Here is the link:

NOTE: This is the best view that I have of the tip of his abdomen. You can see the color and basic shapes that are normally blocked from the view, by bright hairs.
Please confirm, move or frass these images. Thanks for your help!
