The following description is based on the male holotype (MZB. Amph 31765). Calls contained two major types, one containing repeated short notes (type I) and another is containing repeated long notes (type II). Call type I contains 4−22 short notes with call duration of 1.1−6.5 s (mean±SD = 3.8±6.49, n = 3), note duration 116.2−211.5 ms (mean±SD = 137.9±16.18, n = 50), internote duration 141.8−233.8 ms (mean±SD = 185.8±23.53, n = 50), note period 296.4−393.1 ms (mean±SD = 324.0±27.16, n = 50), and dominant frequency 1.8−2.3 kHz (mean±SD = 2.1±0.15, n = 50). Call type II contains 3−6 notes with call dura- tion 1.8−5.8 s, note duration 268.7−885.6 ms (mean±SD = 536.9±195.08, n = 6), internote duration 323.7−535.1 ms (mean±SD = 434.7±75.93, n = 6), note period 679.5−1363.2 ms (mean±SD = 1009.9±26.86, n = 6) and dominant frequency 1.9−2.2 kHz (mean±SD = 2.04±0.1, n = 6). Most of calls contained only type I (Fig. 9A), but one call contained both types and began with a call type II followed by the type I (Fig. 9B).
