 Type locality: America 



Distribution: Chaco, Salta and Misiones (Serie, 1915; Gallardo, 1986; Couturier & Ovalle, 1996; Giraudo, 

 1997). Wide distribution in America, in tropical areas from eastern Mexico to northern Argentina (Myers, 

 1982; Vanzolini, 1986). In Argentina Paranaense and Yungas provinces. The record in Chaco (Las Palmas), 

 possibly corresponds to gallery forests of the Paranaense province. 



Comments: The Argentinian records were considered doubtful by some authors, but the specimens CENAI 

 13486 and 1493 confirmed the species' presence in Misiones and Salta. Without doubts (Giraudo, 1997), 

 Serie 's data (1915) derive from this species. The specimen probably used by Serie is housed at MACN. 

 However, the original label is missing.
