Leptohyphidae (Insecta: Ephemeroptera) from northeastern Brazil

Abstract

New records of Leptohyphidae for Northeastern Brazil are provided.

A new species of Amanahyphes Salles & Molineri, 2006 (Ephemeroptera: Leptohyphidae) from Bahia, Brazil

“…A nymph reported from Maranhão State, Brazil (Mun. Carolina, Rio Itapecuru, S7º 24' 53.2" W 47º 12' 55") by Cruz et al (2011) is not A. saguassu, as previously suspected. The coloration of the body and especially the operculate gills are more similar to A. bahiensis, and thus we consider that A. saguassu is not present in the locality cited by Cruz et al 2011 (Fig.…”

“…Amanahyphes Salles & Molineri, 2006 was described from all stages (male and female adults, egg and nymph) based on material collected from Amazonas state, Brazil. Until now, the only species in the genus has been the type species, A. saguassu Salles & Molineri, 2006, which has been recorded not only from Amazonas, but also from the Brazilian states of Pará (Gonçalves & Da-Silva 2010) and Maranhão (Cruz et al 2011), and from the Venezuelan state of Bolivar (Molineri et al 2011).…”

Assessing the distribution of mayflies (Ephemeroptera: Insecta) in the Brazilian Amazon to guide more effective conservation

“…The potential distributions of these species in the Amazon are restricted to relatively small areas (Figure 5), most of which are affected by intense human pressure, exacerbated by the fact that less than 30% of the potentially suitable area for each species is protected in some way. These species are known from only a few studies, most of which have a taxonomic focus (Salles et al, 2010; Cruz et al, 2011; Shimano, Salles & Juen, 2013; Dias et al, 2019), and all these species were only recently included in the assessment of threatened Brazilian fauna.…”

First record of Amanahyphes saguassu Salles & Molineri (Ephemeroptera: Leptohyphidae) from Colombia and Perú

“…The genus Amanahyphes Salles & Molineri was originally described in Manaus, Amazonas state of Brazil, based on type species A. saguassu Salles & Molineri 2006. Later, the distribution of this species was extended to the Brazilian states of Pará, Maranhão, Mato Grosso and Amapá, as well as Bolivar in Venezuela (Belmont et al, 2012(Belmont et al, , 2015Cruz et al, 2011;Gonçalves & Da-Silva, 2010;Molineri et al, 2011;Salles & Molineri, 2006;Shimano et al, 2010). Recently, Molineri et al (2015) described A. bahiensis in Bahia, a Brazilian state.…”
