We found a single call type for the species, referred to as call A. The call has long duration and is composed of a single harmonic note with a sequence of pulses with interpulse silence intervals. The bands have a general upward FM and a downward FM at the end, yielding a slight arc shape in the audiospectrogram when considering the entire call.

Call A ( Fig. 40 View FIGURE 40 A–H and 33H). We examined seven recordings, a total of eight minutes, with 52 calls from nine males. Only some of these calls were measured (see Table 2 View TABLE 2 ). Call duration varies from 3.854 to 4.920 s. Call rise and fall are very short and similar to each other in duration. There is a long sustain. This segment is usually regular and almost flat but some calls have sustains with a convex shape ( Fig. 40A, D View FIGURE 40 ). The amplitude peak is often at the end of the first seven tenths of the call duration. The envelope of the call is rectangular ( Fig. 40A, D View FIGURE 40 ). More than 50 % of the call energy is concentrated in 45 % of the call duration around the amplitude peak. The call has a strong PAM (there are silence intervals between pulses; Fig. 40A, D View FIGURE 40 ). The rate of the PAM is ca. 15 Hz, forming ca. 55 pulses throughout the call. The pulse rise is longer than fall, with amplitude peak of the pulse at ca. two thirds of the pulse duration ( Fig. 40C View FIGURE 40 ). The amplitude peak of the last pulse is at the beginning or middle of the pulse. Interval durations are similar to pulse duration ( Fig. 40C View FIGURE 40 ). The last pulse is usually the longest (ca. 1.5 times longer than the other pulses; Fig. 40E View FIGURE 40 ). In some calls, the last pulse is the shortest ( Fig. 40A View FIGURE 40 ). The call has a harmonic series ( Fig. 33H View FIGURE 33 ). The fundamental frequency is ca. 330 Hz. The first five harmonics are usually absent in the audiospectrogram. There are ca. four adjacent emphasized harmonics. The wave periods are regular and harmonics are clear throughout the call. The dominant frequency varies from ca. 2340 to 2470 Hz. The dominant harmonic varies from the sixth to the 15 th, but it is usually the seventh ( Fig. 33H View FIGURE 33 ). There is no clear shift in the relative energy between the bands throughout the call. Most of the call energy is between 2100 and 2950 Hz (three harmonics). The call has a general upward FM and a short downward FM at the end, yielding a slight arc shape in the audiospectrogram when considering the entire call ( Fig. 40B, G View FIGURE 40 ). There is a slight PFM throughout the call, which is directly proportional to the synchronic pulse-PAM, i.e. up-downward FM in each pulse ( Fig. 40A, B, C, F View FIGURE 40 ). Additionally, there is another PFM, which is perceptible within the pulses ( Fig. 40H View FIGURE 40 ).
