Lesvi
Lesvi is a Roman Catholic titular bishopric in the former Ecclesiastical province of Mauretania Sitifensis, suffragan of Sitifis, or Sétif, in modern Algeria. It is not, as is sometimes stated, the Island of Lesbos, which never was a titular bishopric, but possesses two titular archbishoprics: Mytilene and Methymna.
Of Lesvi we only know, from the "Itinerarium Antonini", that it was situated twenty-five miles from Tupusuctu or Tiklat and eighteen miles from Horrea Aninici. The town was therefore located on the Sava. However, there are no archaeological remains.
Two of its bishops are recorded: Romanus, a Donatist, present at the convention of Carthage, 411; Vadius, a Catholic exiled by the Vandal King Huneric in 484.

It had had the following incumbents, all of the fitting episcopal rank :
