Type material: Holotype: female on slide (N° 2448 d CM / MNRJ), 2013, Silveira T.C. leg . Paratypes: 20 specimens on slides 2448a CM / MNRJ, 2448b CM / MNRJ, 2448c CM / MNRJ, 2448e CM / MNRJ, 2448f CM / MNRJ, 2448g CM / MNRJ, 2448h CM / MNRJ, 2448i CM / MNRJ, 2448j CM / MNRJ, 2448k CM / MNRJ, 2448l CM / MNRJ) 19/XI/2013, Silveira, T.C. leg . Paratypes: 365 specimens in ethanol (Nº 2448 CM / MNRJ) 19/XI/2013, Silveira T.C. locality the same as holotype

Type locality: National Park of Caparaó (ICMBio), Alto Caparaó municipality, Minas Gerais state, Brazil ( Fig. 1A ). Soil and vegetation of high altitude ecosystem that belongs to the Atlantic Forest biome, where the species of genus Chusquea Kunth , Cortaderia Stapf ( Poaceae ), Baccharis Linnaeus ( Asteraceae ) and Myrsine Linnaeus ( Primulaceae ) stand out. The dark soil suggests presence of peat (peat high altitude) ( Fig. 1B ). Local coordinates: 22°27’10.75”S, 41°48’4.76”W. About 2.400 m a.s.l.
