Resumo: 	Two new species of loricariid catfishes, Parotocinclus bidentatus and P. muriaensis, are described from the rio Paraíba do Sul basin. They possess accessory unicuspid teeth located internally to the series of bicuspid teeth in premaxillary and dentary bones. According to a parsimony analysis of phylogenetic relationships among the Hypoptopomatinae, the new taxa are members of the genus Parotocinclus, even though they lack a fully developed adipose fin. They differ from most species of Parotocinclus because they have accessory teeth. Within the Hypoptopomatinae, accessory teeth are also found only in P. collinsae and members of the genera Eurycheilichtys, Epactionotus and Niobichthys.
