Notes
Most known specimens of P. helenae are from Southeast Brazil, including the holotype and the allotype (both from the state of São Paulo), and eight paratypes (states of Minas Gerais and São Paulo). Only one paratype was collected in the state of Pará, North Brazil. The new records are from the Araucaria Forest province, while the allotype is from the Atlantic province and the paratypes from the state of Minas Gerais are from the Paraná Forest province, but all the three provinces belong to the Paraná dominion. Paratypes from the state of Pará are from the Pará province of the Brazilian boreal dominion. The red label (Fig. 21E) of the holotype of P. helenae is wrongly labelled as P. paulae, but following the original description and comparing the locality label we can conclude that it is the holotype of P. helenae.
