Abstract
The genus Cloeodes is poorly reported for Uruguay, until now only C. aymara was described from this region. Here we describe three new species of Cloeodes from this country: C. dialutoi, C. guenoa and C. vaimaca, all of them based on nymphs. The species C. opacus is reported for the first time in Uruguay. A discussion of each taxon is included as well as drawings of the new species. A revised and updated key for male imagos and nymphs of South American species of Cloeodes is presented.
