Studies on neotropical Protoneuridae. 15. Amazoneura gen. nov. with description of A. juruaensis sp. nov. (Odonata, Zygoptera)

Abstract

The genus Amazoneura is erected to contain A. ephippigera (Selys, 1886), A. westfalli (Machado, 2001) and A. juruaensis sp. nov. The new genus is close to Forcepsioneura Lencioni, 1999 but differs from it mainly by the poorly-developed postero-lateral tubercles of the medium prothoracic lobe, by the dark colour of the metepimerum and of the rear of the head. A. juruaensis sp. nov. (holotype male, Acre, Brazil) differs from the other two species of the genus mainly by the structure of the superior anal appendages.

“…Machado (2004) used this character to separate his new genus Amazoneura (lobes absent or poorly developed) from Forcepsioneura Lencioni, 1999 (lobes strongly developed). Two genera were later synonymized by Lencioni (2005).…”

“…The status of this genus is uncertain. Forcepsioneura ephippigera , originally a Protoneura species (Selys, 1886) was switched consecutively to Epipleoneura (Cowley, 1941), Phasmoneura (Machado, 1985), Forcepcioneura (Lencioni, 1999; new genus) and Amazoneura (Machado, 2004; new genus). Machado (2004) created Amazoneura to include all Forcepsioneura species found in the Amazonian region (the remaining Forcepcioneura are restricted to the Atlantic rainforest) lacking well‐developed lobes on the posterior margin of prothorax and possessing a dark mesothoracic colouration extending ventrally behind the coxae.…”

Checklist of the dragonflies and damselflies from Guyana (Insecta: Odonata), with new records from the country

“…This colorful black and yellow red-eyed damselfly was found at the Berbice River and associated stream, where adults were perching, usually in tandem pairs, along the banks on dense overhanging vegetation or on emergent macrophytes, always close to water's surface. Psaironeura tenuissima (Selys, 1886) [Williamson 1915 as P. cerasina; see Machado 1985] Telebasis demarara (Williamson, 1917) [Williamson 1917] Telebasis simulata Tennessen, 2002. 12 males, 1 female (Fig.…”
