Abstract

Edmulmeatus grandis, n. gen. and sp. (Ephemeroptera : Baetidae) is described from larvae collected from eastern Madagascar. The genus is distinguished primarily by having a relatively very large head capsule, large and robust mandibles with specialized armature, and gills on abdominal segments 2-7 only. The relatively massive mandibles suggest that larvae have unusual feeding habits compared to other baetids, being probably a macrovore-herbivore adapted for cutting and crushing plant food items. Edmulmeatus is possibly related to other Afrotropical genera having two rows of denticles on the tarsal claws.
