Supersonus

Its name is an allusion to the fact that the males, in order to attract the females, produce a very high frequency noise which can reach 150 kHz (using only the right wing).

[1] The Supersonus piercei population is known from Watershed Pericos around the small community of El Salto, in the Valle del Cauca Department of mainland Colombia.

[1] The population of Supersonus undulus inhabits a lowland rainforest environment at Tinalandia, in a private forest preserve between Quito and Santo Domingo de los Colorado in Pichincha Province.

The elevation of the rainforest is 600 m (2,000 ft), the highest of the three population habitats, with a forest typical of the western Andean slopes.

[1] Initially the genus was placed into the Tettigoniidae subfamily Listroscelidinae and considered close in relationship to Arachnoscelis; however, further work led to a placement in the Meconematinae tribe Phisidini.
