Scinax crospedospilus 

(fig. 1 B).

In Atibaia (SP), Scinax crospedospilus  (22.8–30.1 mm SVL; two males) was found at PFI, (ca. 23 º 10 'S, 46 º 31 'W, 900–1,250 m asl). The two males were recorded while calling perched on broad leaves (40–50 cm high) at the margins of an artificial permanent pond at the forest border. Syntopic hylid frogs included Hypsiboas faber  , S. eurydice  , S. hayii  and Dendropsophus minutus  .

The advertisement call (figs. 2 B, 3 A and 4 A-B; Table 1) consists of a single note, with 5–7 structurally complex pulses. The first pulse is generally poorly defined and present much lesser intensity and energy compared with the following pulses. Calls are characterized by ascendant amplitude modulation from the first to the 2 nd – 3 rd pulses and the last pulses present a descendent amplitude modulation. The calls had a mean duration of 358 ± 48 ms, with the last pulse longer than the previous ones and a call rate of 25.5 calls/min. The frequencies ranged between 0.82–5.91 kHz. The calls showed a complex spectral structure with inter-individual variation; two prominent bands can be present, between 1.07–1.66 kHz, the low-frequency band (LFB) and around 2.60–4.10 kHz, the high-frequency band ( HFB). In most analyzed calls the dominant frequency was in the HFB (figs. 2 B and 4 A), but in three calls of one male the dominant frequency was in the LFB (figs. 3 A and 4 B). Most calls showed the dominant frequency concentrated in the pulses in the middle of the call.
