Temnostoma balyras
See the yellow setae on the black portion of the abdomen. T. obscura also has this character but is not found this far south. The only reliable way to distinguish between the two species is an examination of microtrichia on the wing, as T. obscura has no bare spots while T. balyras has extensive bare portions. which we will not see without a microscope. Thus distinguishing between the two in a region where their range overlaps is nearly impossible from a photograph.
