Oh, while we're here we may as well do:
[...]
Equites Promoti Indigenae - IIRC equites promoti were originally the legionary cavalry, you were promoted to them and that is what "promoti" should be taken to mean.
[...]

This makes me wonder...

If the "promoti" in equites promoti means what you say it means, they need not have been former legionary cavalry. AFAIK the equites of the cohortes equitatae were also promoted from the infantry ranks. So the equites promoti could also have been formed from these. This would square better with additional titles like Indigenae.
