The Asian range extends across the East Indies to New Guinea and a single species, the Australian wood frog, has spread into the far north of Australia.
Leopard frog is a generic name used to refer to various species in the true frog genus Lithobates. They all have similar coloration: brown or green with spots that form a leopard pattern.
