Found in a cow pasture adjacent to secondary rain forest.
Possibly a juvenile hong kong whipping frog, although i can't be sure i've never seen one. The coloration, patterns and bumpy skin lead me to think it may be another type.
The true frogs, family Ranidae, have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on most continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Asia, Madagascar, Africa, and from the East Indies to New Guinea; the species native to Australia—the Australian wood frog (Hylarana daemelii)—is restricted to the far north.
