I don't doubt that the i.d of S. selentica is correct, baring in mind who has provided it, but what is it about this specimen that says "selentica" as opposed to "pyrastri"?

Generally, I would be relying on the differences in the abdominal markings between the two species, but in the case of this specimen these markings are not really available. Its always useful to know of other characters to use.
