Cloeodes Traver is atypical among Baetidae (Ephemeroptera) because it seems to possess a unique Pantropical distribution. Thirty‐nine species have been described to date, 26 from the Neotropics, four from the Southern Nearctic, seven from the Afrotropics and two from the Oriental region. Several genera have been considered related to Cloeodes during the last decades, of which the following remain valid: Crassabwa Lugo‐Ortiz & McCafferty, Dabulamanzia Lugo‐Ortiz & McCafferty (both Afrotropical), Bungona Harker (Australasian) and Chopralla Waltz & McCafferty (Oriental). Despite their supposed relationship, a phylogenetic analysis between all of these genera has never been performed. In the present paper, based on an extensive analysis of all genera that have been considered related to Cloeodes, a phylogenetic analysis using morphological characters (continuous and discrete) was performed in order to address the monophyly of the genus Cloeodes within the Cloeodes complex of genera. According to our results, Cloeodes and the complex are paraphyletic. Based on this, Cloeodes is restricted to the New World, Potamocloeon is revalidated to include most representatives of Afrotropical Cloeodes and is divided into two subgenera: Potamocloeon (Africa) and the new Aquaediva (Madagascar). In addition, the concept of Bungona is expanded to include Australasian and Oriental taxa – namely the subgenera Chopralla and the revalidated Centroptella – and finally the new genus Crassolus is established to include C. inzingae comb.n. from Africa.
