Scinax duartei

(fig. 1C).

In Itamonte (MG), Scinax duartei was found at its type locality (Brejo da Lapa, Itatiaia National Park, 22º21’S, 44º44’W, ca. 2,100 m asl). Three males were recorded while calling at the border of a permanent artificial pond perched on grass vegetation about 0.5 m above water. Syntopic hylid frogs included Hypsiboas latistriatus .

The advertisement call (fig. 3B; Table 1) consists of a single note, with 8–11 well defined pulses, regularly spaced throughout the call. The calls had a mean duration of 547±74 ms, with a call rate of 20.3 calls/min. The frequencies ranged between 0.86–4.77 kHz and the dominant frequency is between 1.70–3.10 kHz. First pulses of most calls presented lesser intensity and energy in relation to the remaining ones. Calls were characterized by slight ascendant amplitude modulations from the first to the 3rd or 4th pulses. Slight frequency modulation was generally present in the first third of the calls.
