Phrynobatrachus guineensis is a species of frog in the family Phrynobatrachidae. It is found in Sierra Leone, southern Guinea, Liberia, and western Ivory Coast. Common name Guinea river frog has been coined for it, although it is actually associated with drier parts of primary rainforest.
Phrynobatrachus kinangopensis is a species of frog in the family Phrynobatrachidae. It is endemic to the Kenyan Highlands east of the Great Rift Valley. Both the scientific name and its common names, Kinangop river frog and Kinangop puddle frog, refer to its type locality, Mount Kinangop.
The Natal dwarf puddle frog is a species of frog in the family Phrynobatrachidae. It is found in Angola, Benin, Botswana, Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Eritrea, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Malawi, Mali, Mozambique, Namibia, Nigeria, Rwanda, Senegal, Sierra Leone, South Africa, Sudan, Swaziland, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burkina Faso, Chad, Lesotho, and Mauritania.
Ptychadena guibei is a species of frog in the family Ptychadenidae. It is found in northeastern and eastern Angola, the Caprivi Strip of northeastern Namibia, northern Botswana, northwestern and eastern Zimbabwe, Zambia, southern Democratic Republic of the Congo, Malawi, and northern Mozambique. The specific name guibei honours Jean Guibé, a French zoologist and herpetologist. Common names Guibe's yellow-bellied grass frog, Guibe's grass frog, Guibe's grassland frog, and Guibe's ridge frog have been coined for it.
Ptychadena ingeri is a species of frog in the family Ptychadenidae. It is endemic to the north-eastern Democratic Republic of the Congo where it is known from the Garamba National Park. It is likely to occur more widely, possibly reaching into South Sudan. It is named after Robert F. Inger, an American zoologist from the Field Museum of Natural History. Common name Inger's grassland frog has been coined for it.
Ptychadena nana is a species of frog in the family Ptychadenidae. It is endemic to Ethiopia. It is only known with certainty from its type locality, Arussi Mountains, in the Ethiopian Highlands; these mountains are also referred to as the Arsi Mountains. There is uncertainty regarding reports from elsewhere, which perhaps refer to other, possibly undescribed species. Freilich and colleagues found specimens from the Bale Mountains to be larger than "normal" Ptychadena nana, but that molecular data clustered them with other P. nana. Common names Somali grassland frog and smallest grass frog have been coined for it.
Ptychadena perreti is a species of frog in the family Ptychadenidae. It is found in Cameroon, Gabon, Republic of the Congo, southwestern Central African Republic and northern Democratic Republic of the Congo. It might occur in the Cabinda enclave of Angola and mainland Equatorial Guinea. Common name Perret's grassland frog has been coined for it.
Ptychadena pujoli is a species of frog in the family Ptychadenidae. It is known from Macenta and Sérédou in Guinea, Sukurela in Sierra Leone, and Mount Nimba in Liberia and Ivory Coast. Description of Ptychadena pujoli is based on old museum specimens, and very little is known about the ecology of this relatively recently (1997) described species.
Ptychadena tournieri is a species of frog in the family Ptychadenidae. It is a widespread species in West Africa and found in Senegal, Gambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, and Ivory Coast, as well as in Togo and Benin; it is assumed to occur in Ghana and southeastern Burkina Faso, although it has not been recorded there. On the other hand, some records may refer to other species; the Amphibian Species of the World excludes Gambia and Togo from the distribution. Common names Liberia grassland frog and Tournier's rocket frog are sometimes used.
Ptychadena trinodis is a species of frog in the family Ptychadenidae. Its common name is Dakar grassland frog. It is widely distributed in West and Middle Africa, and following the International Union for Conservation of Nature (IUCN), occurs in Benin, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Gambia, Ghana, Guinea, Ivory Coast, Mali, Mauritania, Nigeria, Senegal, and Togo. Further, records are missing from Guinea-Bissau, Burkina Faso, Niger, South Sudan, and Sudan, but it is presumed to be present in these countries too.
Ptychadena uzungwensis is a species of frog in the family Ptychadenidae. It is found on the East African Plateau in Rwanda, Burundi, and Tanzania in the north and then southward to eastern Democratic Republic of the Congo, northern Angola, Zambia, Malawi, Zimbabwe and uplands of Mozambique. Its common names include Udzungwa ridged frog and Udzungwa grass frog, where "Udzungwa" may also be written Uzungwa, following the spelling that Arthur Loveridge used in the species description for the Udzungwa Mountains, the type locality.
Ptychadena wadei is a species of frog in the family Ptychadenidae. It is endemic to Ethiopia and only known from a small area southeast of Lake Tana, in the upper reaches of the Blue Nile. The specific name wadei honours Edward O.Z. Wade, an English illustrator and herpetology enthusiast who drew some of the illustrations accompanying the species description. Common name Wade's grass frog has been coined for it.
Nimbaphrynoides is a monotypic genus of true toads from highlands in the Mount Nimba region of the West African countries of Guinea, Liberia, and Côte d'Ivoire. The sole species is Nimbaphrynoides occidentalis. Along with Nectophrynoides, Eleutherodactylus jasperi, and Limnonectes larvaepartus, Nimbaphrynoides is one of the only anurans that combine internal fertilization with ovoviparity.
The Korean brown frog is a species of frog in the genus Rana. It is native to the Korean Peninsula and Shandong, China.
The Nimba Range forms part of the southern extent of the Guinea Highlands. The highest peak is Mount Richard-Molard on the border of Côte d'Ivoire and Guinea, at 1,752 m (5,750 ft). "Mount Nimba" may refer either to Mount Richard-Molard or to the entire range. Other peaks include Grand Rochers at 1694 m (5558 ft), Mont Sempéré at 1682 m (5518 ft), Mont Piérré Richaud at 1670 m (5479 ft), Mont Tô at 1675 m (5495 ft), and Mont LeClerc 1577 m (5174 ft), all of them are located in Guinea.
