The song of this species is a soft, uninterrupted trill with the syllable rate of 50/sec (at 26°C); mean syllable duration 0.012 s (SD=0.00101, n=25), with the frequency peak at 12.3–12.9 kHz (Figs. 47D–F). The call is only detectable by the human ear from a distance of a few meters.
The morphology of the stridulatory apparatus resembles that of R. differens but the dorsal aspect of the stridulatory file is longer and not thickened in the middle, the file has 132 teeth (Fig. 11E).
