Distribution. It was described from the Province of Santa Cruz, South Argentina ( Frey 1993), and then found in the Province of Jujuy, in the northern part of the Argentinean Andes ( Smirnov et al. 2006) . Now we add a North Chilean record, also from Andean highlands. Habitually similar specimens were found in Mexican tropical lowlands ( Elías-Gutiérrez et al. 2006, 2008b), but these populations are strongly isolated from the Andean those and need to be accurately revised.
