Same species? The second image is not jacksonii.

One of the pictures shows an umbo (this could be an aging specimen), and the other does not. I’m fairly confident that this species is not A. jacksonii. In fact, it should be examined microscopically to see if it is even in the same group (stirps Hemibapha) with A. jacksonii. With no umbo and rather short marginal striations compared to jacksonii, this species could belong in stirps Caesareae.

Very interesting.
