too should be considered as image suggests a more robust habitus and only a single pair of tiny white macules at elytral margins. It is a cryptic (often nocturnal) ground runner with weak flight ability as compared to skittish C. punctulata. The image is a bit too dark for me to commit to species however.

Actually your image does appear clearer and brighter on a second better monitor other than my home screen. I now feel more confident in my first impression and we should see if other tiger beetle experts agree with C. unipunctata.

...but this is certainly C. unipunctata. I have several specimens taken at that very location.

I wasn't even aware of C. unipunctata, so thank you for the enlightenment. I have, however, encountered plenty of C. punctulata in situations similar to what is described here.
