This katydid with strongly reduced wings is potentially new to science and represents also a new genus. The calling song of the males is quite elaborate but very rarely performed, and lies completely in the ultrasound (between 25 and 35 kHz).
In close contact to the female the male rather seems to rely on vibration signals, produced by rapid body shivering. This behavior is reported for several Neotropical katydids, and is almost certainly an adaptation to avoid being detected by eavesdropping bats.
This potentially new species is fairly common on low vegetation close to creeks and rivers at 850 – 1300 m.
