There are two documented bishops of this diocese: • the Catholic Mariano, who spoke at the
Carthage conference of 411, which saw the Catholic and
Donatist bishops of Roman Africa gathered together; on that occasion the bishopric did not have Donatist bishops; • the bishop Donatus, who took part in the synod gathered in Carthage by the Vandal king of Hungary in 484, after which he was exiled. Today Rufiniana survives as a titular bishop's seat; the current titular bishop is Anton Leichtfried, auxiliary bishop of Sankt Pölten. ==Known Bishops==
