Abstract

The larvae of three known species of Callibaetis are described here for the first time: C. gonzalezi (Nava´s), C. pollens Needham & Murphy and C. sellacki (Weyenbergh). The larva of C. willineri Nava´s is resdescribed and the larva of C. guttatus Nava´s is revised and discussed. The diagnoses of the adults are also provided.
