|Scientific Name:||Ptychadena schillukorum|
|Species Authority:||(Werner, 1908)|
Ptychadena cotti (Parker, 1930)
Pychadena floweri (Boulenger, 1917)
Rana schillukorum Werner, 1908
|Taxonomic Notes:||We follow Perret (1987) and Channing (1993) in considering Ptychadena floweri to be a synonym of P. schillukorum, but note that this opinion is not shared by Poynton and Broadley (1985b). Rödel (2000) considers the matter to be still unresolved. S. Baha El Din (pers. comm.) supports the current arrangement.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||IUCN SSC Amphibian Specialist Group|
|Contributor(s):||Channing, A., Poynton, J., Largen, M.J., Rödel , M.-O. & Baha El Din, S.|
Listed as Least Concern in view of its very wide distribution, its tolerance of a broad range of habitats and its presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species ranges from Senegal, east to southwestern Ethiopia and southern Somalia, south to Malawi, central Mozambique, southeastern Democratic Republic of Congo and western Angola. Although this species is reported from a very wide area in Africa, there are very few records from most of its range, and it has not been recorded from many countries where it is likely to occur. The distribution map is based on the assumption that it occurs in areas between the recorded localities. There are records from Senegal, Ghana, Burkina Faso, Benin, Cameroon, South Sudan, Sudan, Eritrea, Ethiopia, Somalia, Kenya, Tanzania, Malawi, Mozambique, Democratic Republic of Congo and Angola. The populations in northern Eritrea and Egypt (localities in the Nile Delta and at Fayoum) appear to be genuinely isolated. It is presumed to occur in Gambia, Guinea-Bissau, Guinea, Mali, Côte d’Ivoire, Togo, Niger, Nigeria, Central African Republic, Chad, Uganda, and Zambia.|

|Population:||It is apparently common where it occurs, but it is patchily distributed. It is a rare species in Egypt, where it is currently only known from two specimens (S. Baha El Din pers. comm.).|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||It is a savannah species, including in quite arid habitats, and has also been found in grassland, partially flooded rice fields and dry yam fields. It is often seen near rivers and lakes, and it breeds in flooded grasslands, rice fields, and temporary pools. It is known to feed on other frogs and large terrestrial animals (Baha El Din 2005).|
|Use and Trade:||
There are no reports of this species being utilized.
|Major Threat(s):||It is an adaptable species that is not facing any significant threats, except in localized situations.|
|Conservation Actions:||It occurs in several protected areas.|
