Scleronema minutum occurs in the laguna dos Patos system, lower rio Uruguay basin and lower rio Paraná basin. In the former, the species is widely distributed in rivers and streams that drain directly to laguna dos Patos (Brazil) and lagoa Mirim (Brazil and Uruguay). The species is known from only one stream of the right bank of the lower rio Uruguay, the arroyo Yuquerí Chico (Argentina), and widespread in following drainages of its other side: rio Negro (Brazil and Uruguay), rio Ibicuí (Brazil), río Dayman (Uruguay), río Queguay (Uruguay), and río San Salvador (Uruguay). In the lower rio Paraná basin, the species has few records to two tributaries of its left bank, the arroyo Feliciano and río Guayquiraro, Argentina.
