The species is known from four specimens collected in western Kenya (Kakamega), and southern (Madahani, Southern Highlands) and northern Tanzania (Arusha).
Habitat and Ecology
It is associated with emergent vegetation at the margins of swamps, rivers, vleis, lakes and pools in savannah and grassland habitats. Its type locality is a clear, deep pond surrounded by Typha plant species in which it was found perching at water level and up to approximately one meter above water level (Channing et al. 2013). Lötters et al. (2004) found egg clutches attached to submerged vegetation. The larvae are omnivorous, found in quiet water.
This species is presumed to have a large and abundant population, but trends are unknown.
Due to expanding human population, grasslands in the region are being converted to agricultural uses and burned to maintain cattle pasture. Wetlands are likely to also have their water diverted for agricultural purposes. However, localised threats are unknown.
It is likely to occur in several protected areas.
The species requires ongoing and improved protection of its habitat, in particular its wetland habitats, and the specific sites where it has been recorded.
Further work is required to better understand the species' taxonomy and hence its distribution, population size and trends, ecological requirements, and threats.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population and large amount of available suitable habitat.
This species was removed from synonymy with Hyperolius nasutus by Channing et al. 2013.
