Two species (see text) Julianus is a genus of tree frogs in the family Hylidae.

[4] This genus is named after Julián Faivovich, who has contributed a notable amount of knowledge to the study of South American tree frogs.

[5] The species Julianus pinimus was later added to this genus due to having similar features.

However, other papers claim that these frogs are not distinct enough to be grouped into an entirely different genus and should be readded to Scinax.

uruguayus is known from Treinta y Tres, Cerro Largo, and Tacuarembó in Uruguay, along with Santa Catarina, Brazil, and Corrientes, Argentina.
