Remarks.-

The understory can be filled with the loud male calling song of this large cricket during dusk (around 7 pm). The male lives in a burrow and produces loud and high-pitched (peak frequency = 4.2 kHz) trilling (mean pulse intervals = 9.1 ms) calls. As they can be quite abundant, the amount of noise produced can be very loud and heard a distance away. Specimens from Kuala Belalong resemble the images and description by Gorochov (2011) and identification was verified by A.V. Gorochov.
