Glenurus peculiaris (Walker, 1860)

Glenurus peculiaris was the only species of the genus previously known from Brazil. It can be distinguished from the other two species recorded herein to the country by the combination of the presence of a large apical brown mark in the forewing, and the two white spots on the posterior margin of the apical area in the hind wing ( Fig. 2c ). The species has a large distribution in South America, with records from Argentina, Guyana, Paraguay and Suriname, but in Brazil it was only known from two records from São Paulo state ( Stange 2004; 2010; Machado & Martins 2020). These two Brazilian records correspond to the two specimens of the type series of G. brasiliensis Navás, 1920 , a junior synonym of G. peculiaris . The holotype of G. peculiaris , despite being collected in Brazil, had no extra location data on the label. Navás (1920) in the description of G. brasiliensis , mentioned that the female specimen was from Jaragua, which was interpreted by Oswald (2019) as the municipality of Jaraguá do Sul in Santa Catarina state. However, Navás (1923) mentioned that this record was erroneous and that the specimen was actually from nearby the municipality of São Sebastião in São Paulo. Herein, I present the first records of G. peculiaris from four different Brazilian states, Bahia, Minas Gerais, Paraná, and Santa Catarina besides some new records from São Paulo state ( Fig. 5 ), all areas dominated by the Atlantic rainforest biome.
