Zootaxa 2744: 39–52 This genus is a quite ancient member of the true frog family, Ranidae. They are typically found in or near rapidly flowing, small rocky streams, and are sometimes known as splash frogs or foot-flagging frogs. The latter name refers to their unusual behavior of conspicuously waving their hindlegs and feet, as a way of signalling other members of the species.Grafe, Preininger, Sztatecsny, Kasah, Dehling, Proksch & Höd (2012).
