Four new species, a new synonymy and new record for Thraulodes Ulmer 1920 (Ephemeroptera: Leptophlebiidae: Atalophlebiinae)

Abstract

Four new species of Thraulodes Ulmer (Ephemeroptera: Leptophlebiidae), Thraulodes amanda sp. n., Thraulodes pelicanus sp. n., Thraulodes xavantinensis sp. n. and Thraulodes sinuosus sp. n are described based on imagos. A new synonymy (Thraulodes lepidus [Ulmer]=Thraulodes cryptodrilus Nieto & Domínguez) is proposed and the distribution of Thraulodes schlingeri is expanded based on a new record from western Brazil. © 2011 EDP Sciences.
