Abstract

The genus Camelobaetidius Demoulin (Ephemeroptera: Baetidae) is represented in South America by 28 species: 20 of them are described based on nymphs, three based solely on adults, and five based on nymphs and adults (Dominguez et al., 2006; Boldrini & Salles, 2009; Salles & Nascimento, 2009).  As mentioned by Boldrini & Salles (2009), the species of the genus can be divided into three morphological groups: a) those species with the terminal filament reduced and with a projection on the inner margin of the fore femora; b) species with the terminal filament reduced and without a projection on the inner margin of the fore femora; and c) species with the terminal filament almost as long as cerci. Of these five species described based on nymphs and adults, nymphs of four of them present the terminal filament well developed, whereas in only one, C. billi Thomas & Dominique, nymphs present the terminal filament reduced (Dominguez et al., 2006). Importantly, adults of Camelobaetidius whose nymphs present the terminal filament reduced and a projection on the inner margin of the fore femora, as C. leentvaari Demoulin, the type-species, remain unknown.
