Most are restricted to the tepui highlands, but '' S. evansi'' also occurs in lowlands. On most mountains there are only 1–2 species from this genus, but five are known from Mount Ayanganna and the neighbouring Mount Wokomung Mount Wokomung is a sandstone tepui in the Pakaraima Mountains of western Guyana, the summit is 1700 metres. Together with Mount Ayanganna, 37 km to the north, Wokomung constitutes the easternmost tepui reaching above 1500 metres. The slo ... has six species. They are usually found near streams at low levels on branches/leaves or on the ground among vegetation/rocks.

These names refer to its type locality, Groete Creek in the region Essequibo Islands-West Demerara, Guyana, where the holotype was collected by one Dr. R. Evans. Distribution and habitat ''Stefania evansi'' is endemic to Guyana and distributed in forested lowlands of west-central Guyana at altitudes below . Frogs collected at higher altitudes probably represent ''Stefania scalae'', a species that was for a while considered to be synonymous A synonym is a word, morpheme, or phrase that means exactly or nearly the same as another wor ...
