Obviously they haven't made any auxiliary units from that region. It does tell you what units you unlock by building the Foederata city building before you build it. If it listed nothing you'd get nothing.

Though realistically I don't think the romans did any sort of recruiting from the Carthaginian homeland until way after the Marian reforms happened. And by then many of those living there were actually Roman colonists.

Though I do agree that they could make some sort of native unit from there. Not a Carthaginian unit but some African one.

The AOR charts show Auxila being recruited there, so if it's still before the Marian reforms, maybe check after?

Yeah there were native Libyan infantry being recruitable in Sabatra but I somehow even managed to make that unit disappear from the recruitment roster.

It's depended on the building chain you're following. But we don't know at this point in which buildingchain the recruitment options disappear as far as I know.

The TWC Forums are the best place to find your answers.

I can recruit other Native units in Hispania before Marian reforms. Your culture needs to be higher than the Native cultures(Iberian and Carthge among others) Meaning the percentage of Latin versus the others needs to be higher. Also you need to build the public land building chain towards the Military Colony side of things.(helps with cuture conversion) Plus the Legionary fortress. I can recruit Latin type heavy infantry(similar to Principes) until the Marian Reforms then I can get Legionaries. Hope this helps.
