Notes
In Straneo & Ball (1989) the geographical distribution of P. laeve is restricted to “ Espiritu Santo ” (probably a misspelling of the state of Espírito Santo), but the lectotype and the paralectotype are labelled “Novofriburgo”, referring to “Nova Friburgo”, a city in the state of Rio de Janeiro. Those specimens are from the Atlantic province, in the Paraná biogeographic dominion. The new records are from Pampean province in the Chacoan subregion and from the Paraná Forest dominion in the Paraná dominion.
