Vocalization. The composite advertisement call consists of two distinct types of pulsed calls. Call type A (Fig. 5A) is usually the initial call followed by a series of calls of type B (Fig. 5B), e.g. ABBBBB (see example call in Fig. 6). A composite call (A+nB) consists of one call type A followed by 1–12 calls type B (2.48±2.27, n=114 composite calls from 9 individuals). However, call type A can be emitted solely as well. We recorded and analysed advertisement calls of 10 individuals, including the holotype and three paratypes (MNKA 9922, SMF 88450, SMF 88490; Tab. 3). All but one emitted composite calls, resulting in 114 composite calls composed of 114 calls type A and 284 calls type B from 9 individuals. Additionally, 45 solely emitted calls type A from all 10 individuals were included in the analy- ses. In total, 5 to 30 (16.77 ± 8.53) calls type A and 0 to 64 (29.22 ± 19.48) calls type B were analysed per individual. Call duration of a composite call was 143 to 1563 ms (337ms±276). In a composite call, intervals between calls of typeAand B or B and B were 77–119 ms (99 ms ± 9.7). The interval between a composite call (e.g., ABBB interval ABB interval ABB) or solely emitted calls of type A was 0.93–8.40 sec (3.06 sec±1.28; n=126 in- tervals measured from 10 individuals). Numerical call parameters of call type A are as follows (range followed by mean±standard deviation in parentheses): call du- ration 18–66 ms (42±9; n=159); pulses per call 3–9 (5.45 ± 1.14; n = 159); pulse duration 2 – 10 ms (5 ms; ±1; n=579); pulse rate 82–167 pulses/sec (131± 17; n = 159); dominant frequency 3531 – 4565 Hz (4135 ± 209; n=159). Numerical call parameters of call B are: call duration 4 – 23 ms (12 ± 3; n = 284); pulses/call 1–3 (1.8±0.5; n=284); pulse duration 2–17 ms (5 ms; ± 2; n = 253); pulse rate 43 – 250 pulses/sec (154 ± 41; n = 284); dominant frequency 3575 – 4593 Hz (4136 ± 211; n=284).
