The Scinax fuscomarginatus is a type of frog also known as the brown-bordered snouted treefrog. It belongs to the Hylidae family, which includes many treefrogs. This frog lives in many parts of South America.
You can find it in countries like northwestern Argentina, Paraguay, and eastern Bolivia. It also lives in southern, central, and eastern Brazil. Sometimes, it is found in parts of eastern Venezuela, Guyana, and southern Suriname. This makes it one of the most widespread frogs in its region!

About Its Name
Scientists sometimes change how they name animals. Before 2014, several frogs were thought to be different species. These included Scinax parkeri, Scinax trilineatus, Scinax lutzorum, and Scinax pusillus.
However, after studying their genes, scientists realized these frogs were actually the same. They also looked at their bodies and the sounds they made. Because they were so similar, all these names are now considered synonyms of Scinax fuscomarginatus. This means they are all the same species.
What Does It Look Like?
Adult male Scinax fuscomarginatus frogs are quite small. They measure about 16 to 27 millimeters (0.6 to 1.1 inches) from their snout to their rear end. Their head is a bit longer than it is wide.
- Snout: The snout, or nose area, looks like a stretched oval when seen from above.
- Ears: They have a small eardrum, called a tympanum, but it's not very easy to see. Part of it is hidden by a fold of skin above it.
- Fingers and Toes: Their fingers are short and have flat, oval-shaped tips. They have a little bit of webbing between their fingers. Their toes are thin and also have oval tips. The webbing between their toes can vary, but it's usually more developed than on their fingers.
- Color and Pattern: The frog's back, called the dorsum, is usually light brown. It has brown stripes along its sides and sometimes a line down the middle of its back. There's also a stripe between its eyes. These patterns can look very different from one frog to another. The chest and belly are usually plain or have tiny spots.
How Do They Communicate?
Male Scinax fuscomarginatus frogs have a large throat sac, called a vocal sac. They inflate this sac to make calls. Their call is a single, long note made of many short pulses.
The sound lasts for about 0.3 to 0.9 seconds. The main sound frequency is around 3780 Hertz (Hz). This means it's a fairly high-pitched sound.
Where Do They Live?
The Scinax fuscomarginatus frog lives in open areas. These include places like the Pantanal wetlands and the Cerrado savannas. They also live in the Humid Chaco and Beni savanna regions. You can find them in the Chiquitano dry forests too.
Sometimes, they live in open spots within the Atlantic and Amazon forests. These frogs can be found at elevations up to 1,000 meters (about 3,280 feet) above sea level.
Protecting This Frog
The last time scientists checked on this species for conservation was in 2004. At that time, the species was considered "Least Concern." This means it was not in danger of disappearing.
It's important to remember that this assessment was done before scientists realized how widespread this frog truly is. Because it lives in so many different places, it is likely still doing well.
