Holotype and 27 paratypes Museu de Zoologia da USP: 5 paratypes Museum of Comparative Zoology, Harvard University. At the MCZ collection I found 5 more specimens, clearly labelled as paratypes by Kempf himself. To the Tucuman specimens I added a label saying “not in the original description, Brandao, 1985”.
