Selendeta was an ancient civitas of the Roman Province of Byzacena during the Roman Empire and late antiquity. The exact location of the town is unknown [1] but it was somewhere in southern Tunisia.
The town was also the seat of an ancient bishopric which survives today as a titular bishopric of the Roman Catholic Church.[2] The current bishop is Grzegorz Balcerek.[3]
The only known bishop of this diocese is the Donatist Vittorio who participated in the Carthage conference of 411. Today Selendeta survives as a titular bishop's seat; the current titular bishop is Grzegorz Balcerek, auxiliary bishop of Poznań.[4]
