Münzer, De Gente Valeria 50, no. 50, and 38, note 8, identifies this Consul with the Consul of 312 and 289, and explains that the cognomen Potitus is simply a mistake on the part of Fast. Hyd. and Chr. Pasc. However, the Chronographer of 354 does not include the usual mark of iteration. The evidence therefore favors the separate listing found in the Index of CIL 1(2), p. 354, and Degrassi 112. He is not listed in RE in the table found on cols. 2315-2318. (Broughton MRR I)
Chr. 354 (Maximo et Peto); Fast. Hyd. (Potito et Petito), so too Chr. Pasc.; Cassiod. (M. Valerius et C. Aelius); Degrassi 112, 428f. (Broughton MRR I)
