The diocese of Tetci (Latin: Dioecesis Tetcitana) is a suppressed and titular see of the Roman Catholic Church. An exact location of the town is now lost to history but it was in today's Tunisia.[1][2]
The only known bishop of this African diocese is Rustico, who took part in the synod assembled in Carthage in 484 by the Arian King Huneric the Vandal, after which Rustico was exiled. Three years later a council called by Pope Felix III (487) had an African bishop named Rustico participate, but without mentioning the place of residence; may be the bishop of Tetci or the bishop of Tipasa of Numidia.[5]
