A rather tattered creature.

Blue Dasher, Pachydiplax longipennis
Nice photo of a battle-scarred Blue Dasher. The white face is one identification characteristic of Blue Dasher, setting them off from similar-looking species.

I thought briefly of Thornbush Dasher, a Texas species, but after looking at a range map I see that the Thornbush Dasher only ranges into far SE Oklahoma as a vagrant. Thornbush looks similar to blue dasher on the head and thorax, but has spots on the abdomen.

Seems to have a mite on the ventral surface of the thorax where it joins the abdomen.

Blue Dasher
Stephen, thanks for the ID. I just noticed the small red spot when I posted the picture.
Also thanks for the information about being battle-worn. I thought it was just age.

 
Age versus battle wear
Well perhaps a little of each I suspect. Age doesn't help. And you can hear the wings of the males as they clash against each other in territorial disputes—I assume that leads to some tattering. There may even be a nick or two from scrapes with birds, other Ododnates, etc.

I neglected to say before, Nice photo! Nice and sharp on the leg spines, the "fur" on the dorsal side of the thorax, etc.

Blue Dasher
Thanks again Stephen, it was just a matter of having a good subject. He landed about two feet from me at head level and remained there while I took several pictures.
