Small Chimney Bee - Globe Mallow Bee (Lateral Abdomen) - Diadasia diminuta - male

Small Chimney Bee - Globe Mallow Bee (Lateral Abdomen) - Diadasia diminuta - Male
Tonopah Desert, Maricopa County, Arizona, USA
April 26, 2015
Size: 7.5mm
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: In this view, you can see the color and some of the shape of the small, lightened area, at the tip of his abdomen. In brightly sunlit shots, the abdominal hairs will hide this feature.

Please confirm, move or frass these images. Thanks for your help!
