Abstract

Waltz & McCafferty (Ephemeroptera : Baetidae) is shown to be a monophyletic grouping defined by an anteromedially emarginate and laterally expanded and flattened pronotum in the larva. Attempts to restrict the concept of to (Demoulin) and re-erect Gillies, syn. n., for Lugo-Ortiz & McCafferty, Lugo-Ortiz & McCafferty, Barber-James & McCafferty, (Gillies), (Crass) and Lugo-Ortiz & McCafferty, are shown to be based on inconsistent and inadequate morphological features that result in a paraphyletic taxonomy. The unofficial separate treatment of (Gillies & Wuillot) and (Gillies) under Platycloeon Gillies & Wuillot is also shown to be paraphyletic. Barber-James & McCafferty, sp. n., is described from larvae from Guinea, and is distinguished by the combination of a papillate projection on labial palp segment 2, small tubercles on terga 1?8 and abdominal colour pattern. Lugo-Ortiz & McCafferty, sp. n., is described from larvae from the Democratic Republic of Congo, and is distinguished by the combination of a papillate projection on palp segment 2, elongate tubercles on terga 1?9 and abdominal colour pattern. The larva of (Gillies) is redescribed to incorporate morphological features and variability previously not accounted for, and larvae originally assigned to Crass are shown to be equivalent to . New locality data or emendations on locality data are provided for , Barber-James & McCafferty and (Crass).
