Oklahoma Clubtail
Gomphus oklahomensis
Visually, this appears to be a
reasonable Oklahoma Clubtail. See Abbott's Plate 36d. And the
geographic distribution fits.
Abbott (202) writes that "The
face is pale green and the vertex dark brown. The thorax is grayish
green, with a dark middorsal stripe that widens as it approaches
the collar ... The pale middorsal [abdominal] stripe is nearly
continuous in females and tapers to a point on each segment in
males."
This is one of BugGuide's Oklahoma Clubtails.
