Scinax fuscomarginatus is a species of frog in the family Hylidae. It is found in northwestern Argentina, Paraguay, eastern Bolivia, southern, central, and eastern Brazil, and in scattered localities in the lowlands of eastern Venezuela and savannas of Guyana and southern Surinam as well as adjacent Brazil. As currently defined, it is one of most widespread Neotropical frogs; the northernmost records refer to what was formerly recognized as Scinax trilineatus. Common name brown-bordered snouted treefrog has been coined for this species.

starts withAdult males measure 16–27 mm (0.6–1.1 in) in snout–vent length. The snout is subelliptical in dorsal view. The head is longer than it is wide. The tympanum is small and not very distinct; its upper part is hidden by the supra-tympanic fold. The fingers are short and bear elliptical discs; there is some reduced webbing. The toes are slender and bear elliptical discs; the degree of webbing varies but is more developed than in fingers. The dorsum (in preservative) is light brown with a pattern of brown dorso-lateral stripes in combination with a median line and an inter-ocular stripe that show great variability among individuals. The chest and the belly are immaculate or finely pointed.
Males have a large, subgular vocal sac. The male advertisement call a single multi-pulsed note with modulated frequency. The note duration is 0.3–0.9 seconds and the dominant frequency is about 3780 Hz (range 2960–4590 Hz).
