Callibaetis is considered to be one of the most problematic genera among mayflies by a series of taxonomic inaccuracies that have accumulated over the last two centuries. Despite these taxonomic problems, two independent hypotheses of species groups have been proposed. In the first hypothesis, three species groups for North America were proposed, and in the second, three species groups were proposed for South American. In these hypotheses, the generic delimitation and monophyly of Callibaetis have not been evaluated under a cladistic framework. Taking this into account, the objectives of this study were to verify the monophyly of Callibaetis and whether the groups of species proposed for the genus are corroborated as natural. The matrix included 128 morphological characters and one habitat character, 119 discrete characters were compiled (101 of nymphs and 18 of adults), and six imaginal characters are related to pigmentation pattern. Continuous characters were ratios and were represented by 10 characters (nine for nymphs and one for adults). The data set was analysed under implied weights. Group support was estimated with relative Bremer support and frequency differences. The results corroborated the monophyletic nature of Callibaetis and the generic status of Callibaetoides; however, the groups proposed for North and South American Callibaetis species were not corroborated. Our study indicated four groups of species for the genus, which we proposed as subgenera: Callibaetis, Abaetetuba subgen. n. Aiso subgen. n. and Cunhaporanga subgen. n.

The first phylogenetic study of Callibaetis Eaton indicated an unrevealed diversity in this genus, including four new species named as Callibaetis sp. A, B, C and D, and the undescribed nymph of Callibaetis (Abaetetuba) fasciatus (Pictet). Given that neither the nymph of C. (Ab.) fasciatus nor the four new species received a proper description, the objective of this study is to describe them. The nymph of C. (Ab.) fasciatus differs from the others species in the subgenus by the presence of one row of setae on basal part of inner-dorsal row of maxilla and metanotum without spines; Callibaetis sp. A is described as Callibaetis (Abaetetuba) cochlea sp. nov. and differs from the others species in the subgenus by having trapezoid segment III of labial palp in nymphs; Callibaetis sp. B is described as Callibaetis (Aiso) calophenigyn sp. nov. and differs from the others species in the subgenus by the absence of stout setae on dorsal surface of glossa in nymphs, and from the others species in the genus by the forewing with red C and Sc areas in female imago; Callibaetis sp. D is described as Callibaetis (Callibaetis) molinerii sp. nov. and differs from the others species in the subgenus, from South America, by the maxilla with tuft of stout setae on outer margin proximad of palp insertion and paraglossa without row of stout setae on ventral surface; Callibaetis sp. C is described as Callibaetis (Cunhaporanga) imperator sp. nov. and differs from the others species in the subgenus by the presence of a complete row of setae on outer margin of maxilla. Additionally, new keys for species of Callibaetis from South America are proposed.
