Simminensis, also known as Siminina, Siminensis, or Simminensis, means "to sow".

History
Semina is today a titular diocese in the Proconsolare of Carthage. and a number of titular bishops have sat in 20th century. Founded in the Roman era only one bishop is known for certain from antiquity, St. Fiorenzo, who participated in the Council of Carthage (484) convened by the Vandal king Huneric, after which he was exiled to Corsica. Two other ancient bishops from the city are also inferred from literary sources. The first Deuterium Simminensis is mentioned in the Notitia Africae of 484AD, while the second Iunianus or Martin took part in the Council of Carthage (525).

The bishopric is mentioned by Anonymous of Ravenna.
