Two new species of Caenis Stephens, 1835 (Ephemeroptera: Caenidae) from South America

Abstract

Caenis Stephens, 1835 is a relatively diverse South American genus of Caenidae (Ephemeroptera), with 22 recorded species, but much of its diversity remains poorly explored in this region. In the present study, two new species of Caenis with apically pointed forceps are described: Caenis amacayacu sp. nov., based on male adults from Colombia; and C. elidioi sp. nov, based on all life stages from several localities in Brazil.

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

“…En años recientes, el conocimiento del orden en América Latina ha incrementado gracias a estudios entomológicos y al aumento de inventarios de biodiversidad, que han brindado material de alta calidad para la descripción de nuevos géneros y especies (Lima et al 2016, Cruz et al 2017, Cruz et al 2018, Cruz & Hamada 2019. En América del Sur existen hasta la fecha, registros de 14 familias, aproximadamente 112 géneros y 671 especies (Domínguez et al 2019).…”

Leptophlebiidae Banks, 1900 (Insecta, Ephemeroptera) from Maranhão state, Brazil

“…Taxonomic knowledge of Ephemeroptera in Mara nhão state it is still quite incipient, mainly due to the few projects developed and lack of researchers, although there are a few taxonomic studies from the east and south regions of Maranhão (Salles and Serrão 2005;Salles et al 2007;Cruz et al 2011;Lima et al 2011;Boldrini et al 2012;Salles and Domínguez 2012;Lima et al 2016a).…”
