Sylvirana is a group, also called a genus, of frogs. These frogs belong to the family Ranidae, which are often called "true frogs." You can find Sylvirana frogs living across South and East Asia. Their home stretches from northeastern India in the west to China in the north, Taiwan in the east, and Thailand in the south.

Scientists first suggested the name Sylvirana in 1992. For a while, they thought these frogs were a subgenus (a smaller group) within the Rana genus. Later, some thought it was a synonym (another name) for Hylarana. However, in 2015, new studies using molecular genetics (looking at DNA) showed that Sylvirana is unique enough to be its own separate genus.

What Do Sylvirana Frogs Look Like?

Frogs in the Sylvirana group are usually medium-sized. They have strong bodies. A cool feature is the markings behind their eyes, which look similar to those on frogs in the Papurana genus. Their upper lips can be gray, off-white, or have a mixed pattern of colors.

The skin on their back can be rough with tiny bumps, or it might be warty. They have folds of skin along the sides of their backs. These folds are usually medium-sized and easy to see. They might be pale or the same color as the frog's back. The sides of their bodies often have dark colors below these skin ridges. This dark color fades into a lighter shade and has dark spots with clear edges. Male Sylvirana frogs have two vocal sacs, which they use to make sounds. These sacs can be either inside or outside their bodies.
