Fejervarya manoharani
A male (ZSI/WGRC/V/A/950, from Chathankod-Bonnacaud) of Fejervarya manoharani sp. nov. produced a single type of call with a pulsatile temporal structure (Figs. 8E–G). Calls were not delivered in groups and had uniform intervals. A typical advertisement call (Fig. 8F) had a duration of 260.1 ms with 76 pulses delivered at rate of 301.5 pulses per second. Call had a rise time of 127.2 ms and a short fall time of 11.7 ms. The spectrum was characterized by two broad peaks with the overall dominant frequency of 2.6 KHz (Fig. 8H). The animal was recorded on 24 June 2015, between 19:00–21:00 hours. Air temperature at the time of recording: dry bulb 25◦C, wet bulb 24◦C.
In comparison to Fejervarya rufescens, the call of F. manoharani had a higher number of pulses, 76 pulses (vs. 52 pulses in F. rufescens) and was delivered at a faster rate, 301.5 pulses per second (vs. 227.1 pulses per second in F. rufescens). The overall dominant frequency of F. rufescens call (2.9 KHz) was higher compared to F. manoharani (2.6 KHz). The call rise time was also higher in F. rufescens, 221.9 ms (vs. 127.2 ms in F. manoharani), making the calls of both these species considerably distinct from each other (Figs. 8B, 8F). [1]
