São também apresentadas chaves de identificação para os adultos e ninfas de todas as famílias, gêneros e espécies documentadas para o país. Os gêneros incluídos nesse trabalho são: Amanahyphes Salles & Molineri (1 espécie), Coryphorus Peters (1 espécie), Leptohyphes Eaton (5 espécies), Leptohyphodes Ulmer (1 espécie), Macunahyphes Dias, Salles & Molineri (1 espécie), Melanemerella Ulmer (1 espécie), Traverhyphes Molineri (4 espécies), Tricorythodes Ulmer (6 espécies), Tricorythopsis Traver (9 espécies).

Clave taxonómica de ninfas de Ephemeroptera (Insecta) del sudeste de Perú

“…En este estudio se aplicaron dos métodos de recolección: (1) recolecta manual de ninfas en todos los tipos de hábitats, realizada por entomólogos acuáticos de Stroud Water Research Center, y (2) la ubicación de paquetes artificiales de hojas (Inga Mill) por cuatro semanas, para la colonización de macroinvertebrados (STROUD 2010). También se utilizó material de las tesis de Barra (2015) Las ninfas maduras y completas se determinaron taxonómicamente a nivel de género, utilizando claves taxonómicas (Domínguez et al 2006, Domínguez & Fernández 2009) y los artículos de Domínguez (1988), Molineri (2001Molineri ( , 2003Molineri ( , 2004, Molineri y Zúñiga (2004), Salles y Molineri (2006), Dias et al (2007), Boldrini et al (2009) y Flowers y De la Rosa (2010), Lima et al (2019). Además, se revisó el catálogo en línea de las especies sudamericanas (Domínguez et al 2019), "Ephemeroptera Galactica" (www.ephemeroptera-galactica.…”

Description ofLoricyphes froehlichi, a new genus and species of Leptohyphidae (Ephemeroptera) from São Paulo, Brazil

“…The knowledge of the family Leptohyphidae (Ephemeroptera) has been continuously growing in the last years, with many revisionary works and species descriptions (e.g., Wiersema and McCafferty, 2000;Molineri, 2006;Dias et al, 2007;Baumgardner and McCafferty, 2010). In South America 12 genera are recognized (Domı´nguez et al, 2006) In the present paper we describe a distinctive new genus and species based on nymphs, male subimago and eggs, showing a unique morphology in the group.…”

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

“…Amanahyphes shares many characters with Leptohyphodes Ulmer, 1920: male eyes enlarged and divided in two portions, elongate wings, two-segmented forceps arising from posterolateral projections of the styliger plate; nymphal legs long and slender with claws showing two sets of denticles (a marginal row basally and a double submarginal row subdistally) and operculate gills subtrapezoidal in shape, narrowest proximally, and with inner margin nearly reaching midline of the body distally (Molineri 2005, Salles & Molineri 2006. Nevertheless, the penes, the eggs, and the structure of the gills seem different enough to justify the validity of both genera (Salles & Molineri 2006, Dias et al 2007. 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).…”
