In Argentina it had been found only in Misiones, Entre Ríos and the extreme northeast of Buenos Aires provinces (Cei 1980). There are few records for northeastern area of Buenos Aires province (Gallardo 1961) and exists a single record one from then southeastern part (Barrasso and Cajade 2007).Two individuals were found at 21:30 h on January 2nd 2010, in the outskirts of General Villegas, Buenos Aires province (35°1’31” S, 63°0’14” W) (Figure 1). Both were calling from the surrounding vegetation of a temporary pond that was in a wooded area with short grass and scarce aquatic vegetation. The pond had several trees and bushes in one of the edges, mostly Salix sp. The air temperature was 23 °C and the water was 16 °C. We were able to obtain sound recordings and photographs of one individual which was used to obtain the specific identification (Figure 2).
