A new species of the green tree frog have been discovered by scientists in Australia's largest virgin forest in Queensland.
Named Litoria bella, or the Cape York Graceful Treefrog, has distinctive orange hands, feet and iridescent purple inner thighs closely resembling the Graceful Treefrog (Litoria Gracilenta).
The frog had previously escaped scientific scrutiny because it had been mistaken for its southern relative, which is commonly heard calling after rain in spring and summer.
The frog discovered in Queensland's Cape York was only determined to be a new species on September 27 after undergoing rigorous tests for a year, scientist Jodi Rowley told Xinhua news agency.
Rowley said that her colleague Keith McDonald from the Queensland museum had first laid eyes on the Cape York tree frog, scientifically known as Litoria Bella, in 2000 during one of his field-work outings.
However, it was only recently that the frog was determined to be a new species after a science journal verified their work and published the findings of it.
"By looking at differences in its appearance, as well as its advertisement call and DNA, we now conclude that the Cape York Graceful Tree frog is a distinct species, bringing the number of known frog species in Australia to 239," McDonald said in the Australian museum blog.
The discovery of the new frog species was a momentous occasion for the scientists with a third of the world's frogs threatened with extinction, says Rowley.
