Hello, Robert!

Another Acericerus sp. is Acericerus vittifrons, 'the brother' of Acericerus heydenii. Do you know if they differ a lot?
I have never seen
vittifrons here, only
ribauti (which differs quite a lot) and
heydenii, so I'm not 100% sure.
Do you understand a little bit German? (Otherwise I'll try to translate later.) Dr. Herbert Nickel, an accepted authority on cicadas and especially this subfamily (he had established the species
A. ribauti) has explained the diagnostic attributes of
A. heydenii here:

It is possible that the "eye glasses" marking on the pronotum is typical for
A. heydenii (not visible on your photo - as the other mentioned attributes of the face are), but he wanted to take a look at his collection to verify this.
Here is another typical pic of these "eye glasses" on
A. heydenii:
