A new species of Traverella Edmunds, 1948 (Ephemeroptera: Leptophlebiidae) from Brazil

Abstract

A new species of Traverella Edmunds (Ephemeroptera: Leptophlebiidae) is described based on male imagoes from the state of Maranhão, northeastern Brazil. The main characteristics that distinguish the new species from the other species are: 1) subgenital plate forming two lateral, broad projections with two fine, long spines dorsally recurved; 2) penis lobe triangular and apically rounded, with a small ventral projection at apex and a ventral longspine slightly curved and directed to midline.

An updated distribution list of Leptophlebiidae Banks, 1900 (Ephemeroptera: Insecta) for Piauí state

“…In recent years, there has been an increase in studies on the Leptophlebiidae family in Brazil, especially in the Northeast region (e.g., Mariano 2010, Lima et al 2012ab, 2013, Costa & Mariano 2013, Almeida et al 2016, Takiya et al 2016, Lima 2018, Nascimento et al 2019, 2020, Campos et al 2022, Rodrigues et al 2023. Despite these efforts, there is still an imbalance in the number of distribution records for Leptophlebiidae species among the nine states that make up the Brazilian Northeast region.…”
