RANA-SUBAQUAVOCALIS, A REMARKABLE NEW SPECIES OF LEOPARD FROG (RANA-PIPIENS COMPLEX) FROM SOUTHEASTERN ARIZONA THAT CALLS UNDER WATER

Rana subaquavocalis, a distinctive new leopard frog species of the Ran a pipiens complex, is presently known only from the Huachuca Mountains of southeastern Arizona. It can be distinguished from other leopard f rog species on the basis of morphology and mating call characteristics . Males are unusual in that they offer the mating call entirely underw ater from a depth of more than a meter, making it completely inaudible in the air.
