Tapajobaetis, a remarkable new genus of Baetidae with spatulate claws (Ephemeroptera)
Ephemeroptera (Insecta) is a very common and abundant group in freshwater systems. Baetidae is the most diverse family of mayflies in terms of species. During a field trip to a poorly sampled area in the state of Para, Brazilian Amazon, a remarkable new genus of Ephemeroptera was collected. The objective of this work is to describe that new genus and new species.
