Consularis

Consularis is a Latin adjective indicating something pertaining to the position or rank of consul. In Ancient Rome it was also used as a noun (plural "consulares") to designate those senators who had held the office of consul or attained consular rank as a special honour. In Late Antiquity, the title became also a gubernatorial rank for provincial governors.
History.
In the Roman Republic, the term "vir consularis" (rendered in Greek as ὑπατικός, "hypatikos") or "consularis" designated any senator who had served as consul. The distinction was accompanied by specific privileges and honours, and was normally a necessary qualification for a number of magistracies: the posts of "dictator" and his deputy, the "magister equitum" (although some cases seem to refute that), the post of "censor" as well as the governance of certain provinces as proconsuls. The distinction was attached to their wives as well ("consularis femina", in Greek ὑπατική or ὑπάτισσα). Under the Principate, the status of "consularis" could be gained, without holding the consulship, by the gift of the emperor, either through admission to the senate ("adlectio inter consulares") or (more rarely) through the award of the consular insignia ("ornamenta/insignia consularia").
Under the Principate, a number of senior magistracies were created for "consulares":
Provincial governors.
Already during the Republic, certain provinces were reserved for ex-consuls. This tradition carried into the Principate following the grant of an enormous provincial command to Augustus in 27 BC effectively dividing the empire between so-called Imperial and Senatorial provinces. Of the latter, two were specifically reserved for "consulares", the proconsular provinces of Asia and Africa proconsularis. "Consulares" could also hold office in Imperial provinces as the Emperor's legates ("legatus Augusti pro praetore"), alongside legates who held the rank of "praetor" and officials from the equestrian order styled "procuratores".
As the formal title of "legatus Augusti" did not otherwise distinguish rank, those of consular standing occasionally attached the form "consularis" to their title, a practice which became commonplace in the 3rd century. As a result, the latter, simpler title began to replace the formal title, and to acquire a generic meaning of "provincial governor". This evolution was formalized in the reforms of Diocletian (r. 284–305) and Constantine the Great (r. 306–337). Aside from its traditional meaning, designating holders of consular rank, the term "consularis" now came to designate a class of provincial governors. Its holders outranked the "correctores" and "praesides", but were still at the very bottom of the senatorial hierarchy, with the senatorial rank of "vir clarissimus", while a holder of consular rank was styled "vir illustris". In a handful of cases, serving "consulares" were raised to proconsular rank, while Valentinian I (r. 364–375) and Valens (r. 364–378) gave the "consulares" of Numidia the exceptional right to be preceded by six instead of five "fasces"-bearing "lictores".
According to the "Notitia Dignitatum" (circa 400), the following provinces were administered by a "consularis":
The "Notitia" gives the following staff ("officium") for a "consularis" of the West: "princeps officii" (detached from the praetorian prefecture), a "cornicularius", two "tabularii", an "adiutor", a "commentariensis", an "ab actis", a "subadiuva", and various "exceptores" and "cohortalini", i.e. menial staff. For the East, the "officium" was slightly different: "princeps officii", "cornicularius", "commentariensis", "adiutor", "numerarius", "ab actis", "a libellis", and the usual "exceptores" and "cohortalini".
The "Synecdemus", written some time shortly before 535, lists the following provinces under "consulares": 
Europa, Thracia, Macedonia Prima, Creta, Epirus Nova, Dacia Mediterranea, Hellespontus, Phrygia Pacatiana and Phrygia Salutaris, Lydia, Pisidia, Lycaonia, Pamphylia, Lycia, Caria, Pontica Prima (Bithynia), Galatia, Cappadocia Prima, Helenopontus, Cilicia Prima, Cyprus, Syria Prima, Phoenice, Palaestina Prima, Arabia, and one whose name is illegible. 
Following the reconquest of North Africa, in 534, Tripolitania was given a "consularis", while Numidia was downgraded to a mere "praeses". However, in 535 Emperor Justinian I (r. 527–565) carried out a wide-ranging administrative reorganization. The provinces of Palaestina Secunda, Syria Secunda, Theodorias, Osrhoene, Armenia Secunda, Armenia Magna, Cappadocia Secunda, Rhodope, Haemimontus and Augustamnica (this is possibly an error) were placed under "consulares", while Epirus Nova, Dacia Mediterranea, Phrygia Pacatiana, Galatia, Syria Prima and Arabia were placed under governors of other ranks.
