Cardioglossa

Cardioglossa is a genus of frogs in the family Arthroleptidae known as long-fingered frogs. They are native to western and central Africa, with the greatest species richness in Cameroon. They are found near streams in lowland and mountain forests, but also occur in other highland habitats near streams at up to 2700 m in altitude. These are small frogs with a snout-to-vent length of 2 to(-). Some of the more localized species are threatened.
