They are mentioned as Benacens[es] on an inscription.[1][2]
The ethnic name Benacenses appears to be derived from the ancient name of Lake Garda, Lacus Benacus. The latter probably stems from an earlier *benn-āko- (cf. OIr.bennach 'pointed, horned'), built on the Gaulish stem benna- ('point, summit').[3][2]
Around 81–96 AD, they dedicated with the Trumplini a monument to Julia Flavia, the daughter of emperor Titus, in the Roman colony of Brixia (Brescia).[1]
