[3] Ptolemy's Geography usually mentions the same two towns in the same order,[4] although Stevenson's defective English translation gives "Ruspina" and "Rheuspena".
"Ruspae", a Latin feminine plural name, was preferred by Alexander MacBean,[6] William Smith,[7] Morcelli;[8] Mesnage,[2] and the Annuario Pontificio.
[12] In the mid-20th century, a new argument emerged in favour of Koudiat Rosfa, 30 kilometers north of Sfax,[13] because of the discovery in 1947 of an inscription at Henchir Bou Tria[14] that seems to identify that place with ancient Acholla.
[12] Excavations at Koudiat Rosfa have not confirmed the perhaps flattering description applied to the city by Fulgentius's biographer Ferrandus: "a noble town illustrious for its famous inhabitants" (Latin: nobile oppidum clarissimis habitatoribus prorsus illustre).
No longer a residential bishopric, Ruspae (the spelling used in the Annuario Pontificio) is today listed by the Catholic Church as a titular see.
