Baetidae (Insecta, Ephemeroptera) ocorrentes em Roraima, Brasil: novos registros e chaves para gêneros e espécies no estágio ninfal

Abstract

ABSTRACT. Baetidae (Insecta, Ephemeroptera) from Roraima, Brazil: new records and a key to genera and species at nymphal stage. Roraima is one of the Brazilian states where least is known regarding the family Baetidae; to date only four species have been recorded from the state.

An estimate of the potential number of mayfly species (Ephemeroptera, Insecta) still to be described in Brazil

“…This may result in shortcomings and misinterpretations in many areas of research (Mariano and Polegatto, 2011), given the fundamental need for an adequate classification of organisms (Marques and Lamas, 2006). In some extreme cases, new taxa may be falsely described due to the lack of data on one or other life stage (Falcão et al, 2011).…”

“…Current scientific knowledge of the biological diversity of the mayflies (Ephemeroptera) is assumed to be highly deficient, and despite the growth of research in Brazil in recent years (Falcão et al, 2011;Shimano et al, 2013), additional studies will be necessary to overcome the limitations of the available data, as well as covering the considerable gaps that persist in the understanding of the taxonomy of the order (Salles et al, 2004b).…”

“…Until the 1980s, most of the published studies focused on taxonomy and systematics, and few data were provided on the biology or geographic distribution of the species (e.g. Walker, 1853;Froehlich, 1969;Da-Silva, 1997;Salles et al, 2004a;Falcão et al, 2011).…”

A cladistic approach for generic delimitation of Paracloeodes Day, Rivudiva Lugo-Ortiz & McCafferty, and Varipes Lugo-Ortiz & McCafferty (Ephemeroptera: Baetidae)

“…Meanwhile, Falcão et al (2011) reported an atypical species of Baetidae from Roraima state, Brazil, and considered that it should be placed in a new genus, but it was not described (here designated as Gen. A). However, this taxon could be also placed in Paracloeodes based on the large spectrum of characteristics attributed to this genus.…”
