We present new geographic records of three species of the genus Hydrolaetare and contribute to the identification of these by providing illustrations and a brief discussion on fixed morphological differences among them. Our records extend the known distribution ranges of Hydrolaetare dantasi and Hydrolaetare schmidti to Amazonas and Roraima states, Brazil, respectively. Hydrolaetare caparu is recorded for the first time in Brazil. The species of Hydrolaetare can be mainly distinguished by the combination of ventral colour pattern and external morphological characters (toe-webbing formula).
