Abstract

Three known species of Macrogynoplax Enderlein from Amazonas, Brazil are redescribed: M. delicata Ribeiro-Ferreira & Froehlich, from neotype, present designation; M. poranga Ribeiro-Ferreira & Froehlich, from neotype, present designation; M. pulchra Ribeiro-Ferreira & Froehlich from holotype and M. anae new species is described. A key to males is presented. M. marauia Froehlich is considered a junior synonym of M. delicata.

A new species and notes on Perlidae (Plecoptera) from Paraná and Santa Catarina States, southern Brazil

“…Perlidae is the largest family of Plecoptera and more than 100 species have been described from Brazil (Froehlich, 2010), primarily in last three decades (Froehlich, 1984(Froehlich, , 1988(Froehlich, , 2002Bispo & Froehlich, 2004a;Ribeiro & Rafael, 2007, Righi-Cavallaro & Lecci, 2010Righi-Cavallaro & Froehlich, 2013). The taxonomic knowledge of this family for southern Brazil, which comprises Paraná, Santa Catarina and Rio Grande do Sul states, is based mainly on specimens collected by Fritz Plaumann in Nova Teutonia, Santa Catarina State (Jewett, 1959;Froehlich, 2002).…”

Description of immatures associated with adults of two species of Macrogynoplax Enderlein and one species of Enderleina Jewett (Plecoptera: Perlidae) of the Brazilian Amazon

“…The 14 known species occur at both high and low altitudes. However, the genus is apparently uncommon in the Central Amazon (Ribeiro-Ferreira & Froehlich 1999, Bobot & Hamada 2002, Ribeiro & Rafael 2007, Fochetti & Tierno de Figueroa 2008, Froehlich 2010, 2012. Seven species of Macrogynoplax have been previously recorded from Brazil and six of these occur in the Brazilian Amazon (Stark et al 2009, Froehlich 2010.…”

“…This increases the number of known nymphs of Macrogynoplax from the Brazilian Amazon to four. Previous studies in which Macrogynoplax species were described include Ribeiro & Rafael (2007) Stark (1996)…”
