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.…”

Tricorythodes macuira (Ephemeroptera: Leptohyphidae), new species from Colombia

“…The genus is currently known from 58 species (some of them included in other genera by some authors, Wiersema & McCafferty 2000, Baumgardner & Avila 2006. In South America, 24 species are described (Dias & Salles 2006, Dias et al 2009, Emmerich 2007, Gonçalves et al 2010, Molineri 2002, Molineri & Zúñiga 2006, Dias et al 2011, Belmont et al 2012, Souto et al 2017. In Colombia the genus is represented only by five species: T. zunigae Molineri from Chocó; T. trifasciatus Molineri and Zúñiga from Valle del Cauca; T. capuccinorum Emmerich and T. uniandinus Emmerich both from Cundinamarca, and T. caunapi Dias, Bacca and Ferreira from Nariño (Molineri 2002, Domínguez et al 2006, Emmerich 2007, Molineri & Zúñiga 2006, Dias et al 2011).…”

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

“…The penes of Amanahyphes show small spines subdistally on the lateral margin (no such spines found on Leptohyphodes); the eggs present a blunt polar cap formed by coiled threads and on the other pole a large conic structure composed of triangular plates (only one polar cap in Leptohyphodes); finally, the gills do not have small, flap-like lamellae on the ventral side (present in Leptohyphodes) (Salles & Molineri 2006). The nymphs can be found in streams and rivers, mainly on submerged roots and marginal vegetation, but also on inorganic substrate such as sand, gravel and stones (Belmont et al 2012). Adults are attracted to lights, but the nuptial flight is unknown (Salles & Molineri 2006).…”
