Ptychadena is a genus of frogs in the grassland frog family, Ptychadenidae. They are distributed in Sub-Saharan Africa, as well as nilotic Egypt. The common names of this genus are ridged frogs and grass frogs. This type of family have many different characteristics such as the species, Ptychadena neumanni who have long hindlimbs and a large ear drum compared to the Ptychadena erlangeri, for example. They also have a unique bone structure which is a fusion between the presacral vertebrae and sacrum.
Ameerega ingeri, also known commonly as Niceforo's poison frog, Brother Niceforo's poison frog, or Inger's poison frog, is a species of frog in the family Dendrobatidae. The species is endemic to the Colombian Amazon. It is known with certainty only from its type locality in the Caquetá Department. Records from the Putumayo Department ascribed to this species likely refer to Ameerega bilinguis, although other sources continue to include Putumayo in the range of Ameerega ingeri.
Leptopelis oryi, also known as the Garamba forest treefrog and Ory's tree frog, is a species of frog in the family Arthroleptidae. It is found in the northeastern Democratic Republic of the Congo, northwestern Uganda, and adjacent South Sudan. It is morphologically similar to Leptopelis nordequatorialis from Cameroon, and has also been considered its synonym, but is currently treated as a distinct species. The specific name oryi honours Albert Ory, warden in the Garamba National Park, the type locality of this species.
Leptopelis parvus, also known as the Kanole forest treefrog, is a species of frog in the family Arthroleptidae. It is endemic to the Democratic Republic of the Congo and is only known from the Upemba National Park.
Yunganastes fraudator is a species of frog in the family Strabomantidae. It is endemic to Bolivia and found in the Cochabamba Department to the border with the Santa Cruz Department. It is sometimes known as Cochamba robber frog. Its specific name fraudator means "cheat" or "deceiver" and refers to its resemblance with Gastrotheca marsupiata.
Gastrotheca ochoai is a species of frog in the family Hemiphractidae. It is endemic to southern Peru and occurs in the interandean valleys on the eastern face of the Andes. The specific name ochoai honors Oscar Ochoa Mendieta, a biology professor from the National University of Saint Anthony the Abbot in Cuzco who helped the species descriptors during the field work. Common name Chilca marsupial frog has been coined for this species.
Megophrys parallela is a species of frog in the family Megophryidae. It is endemic to Sumatra and known from a number of localities on mountains along the island's western coast where it is expected to have a wide distribution.
Amolops spinapectoralis is a species of frog in the family Ranidae, the "true frogs". It is at present only known from a few locations in central Vietnam—that is, it is endemic to Vietnam—but it is likely to be found more widely in the Vietnamese Central Highlands as well as in the adjacent southeastern Laos and northeastern Cambodia. The specific name spinapectoralis is derived from Latin spina for "thorn" and pectoralis for "of the breast" and refers to the pectoral spines in adult males. Common name spinyback torrent frog has been coined for it.
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 harenna is a species of frog in the family Ptychadenidae. It is endemic to Ethiopia and only known from its type locality at the foothills of the Bale Mountains, in the Bale Mountains National Park. The locality is within the Harenna Forest, and common name Harenna Forest grass 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 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.
Philautus bunitus is a species of frog in the family Rhacophoridae. It is endemic to Malaysian Borneo and inhabits subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests and is threatened by habitat loss.
Philautus ingeri is a species of frog in the family Rhacophoridae. The species is endemic to northern Borneo, where it is found in Sabah, Sarawak, Brunei, and adjacent northern Kalimantan (Indonesia). The common names Inger's bush frog and Inger's bubble-nest frog have been coined for it. It is named for Robert F. Inger, American zoologist from the Field Museum of Natural History.
Leptomantis rufipes is a species of frog in the family Rhacophoridae. It is endemic to Borneo and known from isolated locations in south-central Sarawak and eastern Sabah and central Kalimantan (Indonesia). Common names Malaysian flying frog and red-legged frog have been coined for this species. The specific name rufipes refers to the red webbing of this frog.
