Taxonomic Notes: There has been considerable debate on the taxonomic status of this species and others in the Hyperolius nasutus complex. Here we follow Channing, Moyer and Burger (2002) in considering Hyperolius acuticeps to be distinct from H. nasutus, but we do not consider H. lamottei to be a synonym of H. nasutus (following Rödel and Ernst (2003)), nor do we consider H. benguellensis to be a synonym of H. nasutus (following Schiøtz and van Daele (2003)). We also assign records from the Cabinda Enclave of Angola, western Democratic Republic of the Congo, Congo, Gabon and southern Cameroon to Hyperolius adspersus (following Amiet (2005)). Amiet (2005) also suggests that records from northwestern Zambia (Schiøtz and van Daele 2003) might belong to an undescribed species.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2009
Date Assessed: 2008-01-01
Assessor(s): Schiøtz, A., Channing, A., Burger, M. & Largen, M.
Reviewer(s): Stuart, S., Chanson, J. & Cox, N. (Global Amphibian Assessment Coordinating Team)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
Previously published Red List assessments:
2004 Least Concern (LC)

Geographic Range [top]

Range Description: This species ranges from northern Botswana, northern Namibia and western Zambia, north to northern Angola. It is presumed to occur in southwestern Democratic Republic of the Congo, but there do not appear to be any confirmed records. It might occur in northwestern Zimbabwe, but its distribution is very poorly known. Records from northwestern Zambia possibly belong to an undescribed species. It has recently been reported from Côte d'Ivoire (Rödel et al. 2006) and northern Benin (Nago et al. 2006).

Habitat and Ecology [top]

Habitat and Ecology: It is associated with emergent vegetation and sedges at the margins of swamps, rivers and lakes in savannah and grassland habitats. It can be found around human settlements. It breeds in swamps, shallow pans, emergent vegetation, vleis, lakes, permanent and temporary pools and ponds. A prolonged breeder, it begins reproduction 2-5 months after the beginning of the rainy season. Females were found to lay an average of 150 and 199 eggs over two sampling periods (Rödel et al. 2006).
Systems: Terrestrial; Freshwater
