Taxonomy of the genus Adebrotus Lugo-Ortiz & McCafferty (Ephemeroptera: Baetidae)

Abstract

The taxonomy of the enigmatic genus Adebrotus Lugo-Ortiz & McCafferty is reviewed in the present paper. The type-species, A. amazonicus Lugo-Ortiz & McCafferty, is redescribed based on nymphs from Northern Brazil. Adebrotus lugoi, new species, is described based on nymphs from Southeastern Brazil, significantly extending the distributional range of the genus. In the light of these new evidences, the generic concept of Adebrotus is improved. © 2010 EDP Sciences.
