Ephemeroptera (Insecta) from Pernambuco State, northeastern Brazil / Ephemeroptera (Insecta) do Estado de Pernambuco, nordeste do Brasil

The first list of the species of Ephemeroptera from Pernambuco State, Northeastern Brazil, is presented. The survey was based on collections from numerous rivers and streams of 17 counties. A total of five families, 28 genera, and 38 species were recorded, including 22 genera and 31 species newly recorded from Pernambuco State. Moreover, Farrodes tepui Domínguez, Molineri & Peters, 1996, Lisetta ernsti Thomas & Dominique, 2005, and Simothraulopsis (Maculognathus) sabalo Kluge, 2007 are recorded for the first time to Brazil.

Espécies de Baetidae (Ephemeroptera) do Sul da Bahia, com descrição de uma nova espécie de Paracloeodes day / Species of Baetidae (Ephemeroptera) from Southern Bahia State, Brazil, with description of a new species of Paracloeodes day

Based on collections in five municipalities from southern Bahia, a new species, Paracloeodes quadridentatus sp. n., is described from Brazil. It can be distinguished, among other characteristics, by the presence of three, often four, well developed denticles on the tarsal claws, a characteristic that has never been found in other species of the genus. Besides the description of the new species, the following 14 taxa of Baetidae are recorded for the first time from the State of Bahia: Americabaetis alphus Lugo-Ortiz & McCafferty, Americabaetis labiosus Lugo-Ortiz & McCafferty, Aturbina georgei Lugo-Ortiz & McCafferty, Baetodes sp., Callibaetis sp., Camelobaetidius francischettii Salles Andrade & Da-Silva, Camelobaetidius lassance Salles & Serrão, Camelobaetidius sp. 1, Camelobaetidius sp. 2, Cloeodes cf. opacus Nieto & Richard, Cryptonympha dasilvai Salles & Francischetti, Spiritiops silvudus Lugo-Ortiz & McCafferty, Waltzoyphius fasciatus McCafferty & Lugo-Ortiz e Zelusia principalis Lugo-Ortiz & McCafferty. As this is the first survey of Baetidae from Bahia, and it was restricted to the southern part of the state, sampling efforts in other areas are extremely required and should increase considerably the number of species, or even genera, reported from the state.
