Ratcheting toadlet

The ratcheting toadlet (Uperoleia stridera) is a species of small frog that is endemic to Australia.

The specific epithet stridera, as well as the common name, refer to the grating nature of the call.

The ratcheting toadlet was split in 2014 from the blacksoil toadlet (Uperoleia trachyderma), with the populations in the western part of the range being assigned to the new species.

[2] The species' known range extends from Fitzroy Crossing in the southern Kimberley region of Western Australia, extending eastwards to just west of Daly Waters in the Northern Territory, in the western part of the Northern Deserts region of the continent.

[2][1] There it occupies blacksoil plains in tropical savanna country.
