Physalaemus lateristriga (Steindachner, 1864)

We found a single call type for the species, referred to as call A. The call is composed of a single harmonic note with a long duration and a slight PAM (no silence intervals between pulses). It has irregular and strong PFM throughout the call. The bands have no general FM or only slight general FM, which is usually upward.

Call A ( Fig. 43 View FIGURE 43 A–F and 42B). We examined seven recordings, a total of 20 minutes, with ca. 160 calls from 16 males. Only some of these calls were measured (see Table 2 View TABLE 2 ). Call duration varies from 1.330 to 3.746 s. The call rise is restricted to the very beginning of the call, most of the call corresponding to the sustain ( Fig. 43C View FIGURE 43 ). Call rise and fall are very short and similar to each other in duration. Sustain usually regular and almost flat ( Fig. 43C View FIGURE 43 ), but some calls have convex or inclined segments, with amplitude gradually increasing towards its end ( Fig. 43A, D View FIGURE 43 ). In some calls, there is a shallow valley at the beginning of the sustain ( Fig. 43A, C View FIGURE 43 ). The amplitude peak is at around the middle or at the end of the call duration. The envelope of the call varies from rectangular ( Fig. 43C View FIGURE 43 ) to triangular (pointed left; Fig. 43A, D View FIGURE 43 ). More than 50 % of the call energy is concentrated in 39 % of the call duration around the amplitude peak. The call has a slight PAM (silence intervals absent between peaks; Fig. 43A, D View FIGURE 43 ). The rate of the PAM is ca. 8 Hz, forming ca. 29 cycles throughout the call. The cycle rise and fall are similar and the amplitude peak is at the middle of the cycle duration. The call has a harmonic series ( Fig. 42B View FIGURE 42 ). The fundamental frequency is ca. 170 Hz. The first five harmonics are usually absent in the audiospectrogram or with very low energy. There are ca. eight adjacent emphasized harmonics. The wave periods are regular and harmonics are clear throughout the call. Subharmonics (f 0 1/2) are present at the beginning of some calls ( Fig. 43B, F View FIGURE 43 ). The dominant frequency varies from ca. 1590 to 1840 Hz ( Fig. 43B View FIGURE 43 ). The dominant harmonic varies from the ninth to the 13 th, but it is usually the ninth or 10 th ( Fig. 42B View FIGURE 42 ). There is no clear shift in the relative energy between bands throughout the call. Most of the call energy is between 1100 and 2150 Hz (seven harmonics). Calls usually lack a clear general FM ( Fig. 43B, E View FIGURE 43 ). In some calls, a slight up or downward general FM is observed, usually upward. A short downward FM is frequently present at the end of the call ( Fig. 43E View FIGURE 43 ). Additionally, there is a strong PFM throughout the call, which is usually independent ( Fig. 43C, E View FIGURE 43 ), but it is directly proportional and synchronic to PAM when it is present ( Fig. 43A, B View FIGURE 43 ).
