What is "musulamii"

The Musulamii were a confederation of Berber-speaking Gaetulian tribes, of the Mauri ethnos, who inhabited the desert regions of what is today known as Chotts Regions in Tunisia and Algeria, as well as the Roman province of Mauretania Caesariensis, which was annexed to the Roman empire in 44 AD.They were indeed meant to be recognized as a member of these tribes and not separate, as Junius Blaesus the younger describes a war against Tacfarinas a war against the Gaetulas Gentes ("Gaetulian Peoples").
