This toad from the Nectophrynoides genus is one of 15 amphibian species in Tanzania that have been described for the first time. They were found during research led by UK conservation charity Frontiers.
This species of Nectophrynoides is still new to science and has not been given a common name yet. Researchers say it is the largest toad to have been found in the genus.
As well as their distinctive markings and colourings, the researchers say Nectophrynoides are also unique because females give birth to offspring rather than lay eggs.
The researchers say that the range of these frogs appears to be restricted to a few remote valleys deep in the mountain forests of eastern Tanzania.
This species of burrowing toad, with its long nose, belongs to the genus Probreviceps. Its habitat in Tanzania's mountain forests is under threat from deforestation, the researchers warned.
Researchers believe this tree frog is a new species within the Leptopelis genus because it was found at higher altitudes than the similar looking Leptopelis parkeri (Parker's forest tree frog)
