Scinax x-signatus (common name: Venezuela snouted treefrog or Venezuelan snouted treefrog) is a species of frog in the family Hylidae. It is found in Brazil, the Guyanas (Guyana, French Guiana, Suriname), Venezuela and Colombia. Introduced populations exist on Guadeloupe and two nearby smaller islands, Marie Galante and La Désirade, and on Martinique. It may represent more than one species.
Scinax x-signatus is a very common frog inhabiting tropical savannas, forest edges, and open areas, and is very adaptable to habitat modification. It is considered an invasive species on Guadeloupe, threatening native frogs through competition.
