the measurements are in correct that is why i never use them. this sample was 9.5-10-5mm.

here are the features that lead directly to form then to valid species. on the frontale shelf the forwardmost of the head there are black lines on either side. there are black spots on top of the head close to the compound eyes, there is a medial black spot on the pronotum, and one on either side of the notum, on the top and dead center of the notum is a mild faint black stripe, on the sides of the thorax there are pleura streaks, there are numerous heavy black crossveins, all ten tergites have transverse bands, and most importantly there a pale spiracular spots on the lateral areas of each abdominal segments. the only form in the genus that have all these details is the former species ohionese. Ohioense has been clumped in the interpunctatum complex since 1947.

your are correct that it is a Stenacron interpunctatum However

(Stenacron interpunctatum / ohioense) is more correct.
