Table 1. Quantitative measurements of the advertisement call and of the putative agonistic call (“call type II”) of Phyllodytes magnus sp. nov.
Data is presented as mean ± standard deviation (min–max). See text for explanation of measured parameters. –: not measured, see text for explanation. n of advertisement calls (for the first three parameters) is 48 and 6 for MZUESC 18264 and MZUESC 18265, respectively. n of notes of advertisement calls (for the other parameters) is 91 and 63 for MZUESC 18264 and MZUESC 18265, respectively. For call type II, n of calls is eight and n of notes is 24.
