Oligoneuria macabaiba sp. nov. (Insecta: Ephemeroptera) from Brazil

Abstract

The former monotypic genus Oligoneuria Pictet was known solely by a female subimago of the type-species Oligoneuria anomala Pictet. A new species of the genus Oligoneuria from the Atlantic rainforest of Macaé, Rio de Janeiro is described. The description was based in males and females imagos of Oligoneuria macabaiba sp. nov. caught with light traps. This species presents similar wing venation, abdominal posterolateral spines, as well as a membranous extension on anterior portion of the head as seen in the genus. Based on features of the new species, the genus is herein redefined. The species represents the first record of the genus from Southeastern Brazil.

“…After that a new species was also described from Rio de Janeiro, Oligoneuria macabaiba Gonçalves et al (), based on male and female imagos. Consequently, four nominal species are currently assigned to Oligoneuria : O. anomala (type species, from Atlantic Forest), O. amazonica (Brazilian Amazon), O. itayana (Peruvian Amazon) and O. macabaiba (Brazilian Atlantic Forest).…”

“…According to Kluge (2007), all species of this group probably have complete venation in the nymphal stage, but veins may disappear or be retained in the alate stages. Because of that, Kluge (2007) stated that separation of the two genera could not be justified: Oligoneurioides, therefore, was regarded as a junior synonym of Oligoneuria, Oligoneurioides amazonicus was transferred to Oligoneuria, and a new species -Oligoneuria itayana Kluge -was described. After that a new species was also described from Rio de Janeiro, Oligoneuria macabaiba Gonçalves et al (2011), based on male and female imagos. Consequently, four nominal species are currently assigned to Oligoneuria: O. anomala (type species, from Atlantic Forest), O. amazonica (Brazilian Amazon), O. itayana (Peruvian Amazon) and O. macabaiba (Brazilian Atlantic Forest).…”

Study of the mayfly order Ephemeroptera (Insecta) in Brazil: a scienciometric review

“…Recently, however, it has been possible to observe a progress in the study of this order in Brazil following the growing number of publications (e.g. Brito et al 2011;Gonçalves et al 2011a;Gonçalves et al 2011b;Lima et al 2011;Mariano 2011;Molineri et al 2011;Souto et al 2011;Boldrini et al 2012;Couceiro et al 2012).…”
