Astylosternus nganhanus is a species of frog in the family Arthroleptidae. It is endemic to Cameroon and known from Mount Nganha on the Adamawa Plateau; [2] it is probably endemic to that area. [1] Common name Nganha night frog has been coined for it. [2] [3] This poorly known species is only known from five specimens. [1] [3]
Adult measure about 45 mm (1.8 in) in snout–vent length. The head is very narrow, triangular, and flattened in shape. The eyes are rather small and do not protrude greatly. The fingers are fairly short and slender. The hind-limbs are relatively short, and the toe tips are not dilates into discs. Skin is smooth, apart for some longitudinal fine wrinkles, in particular on the flanks. The colouration is dark with black patterning. The top of arms and fore-arms have large, raised black bumps. The thighs have only few markings. Dark pigmentation is also present under the throat and along the ventral surfaces. [3]
Astylosternus nganhanus occurs along watercourses in a few narrow gallery forests, and in seepage areas in the nearby grassland, at elevations of 1,400–1,700 m (4,600–5,600 ft) above sea level. Tadpoles probably belonging to this species have been found in rock pools in streams. [1]
This species, known from only a single population, is probably at severe risk from habitat loss caused by smallholder farming activities and subsistence wood extraction. It is not known to occur in any protected areas. [1]
Arthroleptis variabilis is a species of frog in the family Arthroleptidae. It is found in the lowlands of eastern Nigeria, Cameroon, Equatorial Guinea, Gabon, the Central African Republic, the Republic of the Congo, and the Democratic Republic of the Congo. Earlier records west from Nigeria refer to other species, including Arthroleptis krokosua described in 2008. Common names Buea screeching frog and variable squeaker frog have been coined for it.
Cardioglossa alsco is a species of frog in the family Arthroleptidae. It is endemic to Cameroon and is known from its type locality on southern slopes of the Tschabal Mbabo Mountains as well as from the Gotel Mountains, both in the Adamawa Region. Its range might extend into Nigeria. The specific name alsco is a patronym for the American Linen Supply Company (ALSCO). The company's German branch supported the expedition during which this species was discovered.
Astylosternus fallax, also known as the Fopouanga night frog, is a species of frog in the family Arthroleptidae. It is endemic to southwestern Cameroon where it is known only from between Yabassi and Nkongsamba, from Mount Yuhan in the Korup National Park, and from Mount Nta Ali in the Mamfe basin.
Astylosternus laurenti is a species of frog in the family Arthroleptidae. It is endemic to Cameroon. Its natural habitats are subtropical or tropical moist lowland forests and rivers. It is threatened by habitat loss.
Astylosternus montanus, also known as the mountain night frog or montane night frog, is a species of frog in the family Arthroleptidae. It is found in the mountains of western Cameroon and into the Obudu Plateau in adjacent southeastern Nigeria.
Astylosternus perreti is a species of frog in the family Arthroleptidae. It is endemic to western Cameroon and known from Mount Manengouba and from parts of the Bamileke Highlands, at elevations of 1,200–1,400 m (3,900–4,600 ft) above sea level. It is one of the few species of African frogs to have claws, used on demand, when it feels threatened.
Astylosternus rheophilus is a species of frog in the family Arthroleptidae. It is endemic to western Cameroon. Common name Cameroon Range night frog has been coined for it. Two subspecies are recognized:
Astylosternus schioetzi is a species of frog in the family Arthroleptidae. It is endemic to south-western Cameroon and is only known from two areas near Edéa, Apouh and Koupongo, separated by the Sanaga River. The specific name schioetzi honours Arne Schiøtz, a Danish herpetologist who has worked extensively on African tree frogs. Common name Apouh night frog has been coined for this species.
Werneria bambutensis is a species of toad in the family Bufonidae. It is endemic to western Cameroon where it occurs at high altitudes between Mount Manengouba and Mount Oku, including the eponymous Bamboutos Mountains. It is also known as the Bamboutos smalltongue toad and Bambouto torrent toad.
Dryaderces inframaculata is a species of frog in the family Hylidae. It is endemic to Brazil and known from between the Tapajós and Xingu Rivers in Pará. Until recently, it was only known from one specimen collected near Santarém, probably around 1876, by Henry Wickham. Common name Santarem treefrog has been coined for it.
Hyperolius camerunensis is a species of reed frog in the family Hyperoliidae. It is endemic to western and southwestern Cameroon.
Hyperolius igbettensis is a species of frog in the family Hyperoliidae. It is found in West Africa from Guinea eastward to Liberia, Ivory Coast, Ghana, Togo and Benin, Nigeria, and into Central Africa at least to Cameroon but likely further east to the Central African Republic and southwestern Chad; the eastern border of distribution of this species relative to other members in the Hyperolius nasutus complex is unclear. Common name Igbetti long reed frog has been coined for it. The type locality is near Igbetti, a village in Oyo State, Nigeria.
Eleutherodactylus tetajulia is a species of frog in the family Eleutherodactylidae. It is endemic to southeastern Cuba and is known from the Sierra de Cristal, Monte Iberia, Tetas de Julia, and Meseta del Toldo in the Holguín and Guantánamo Provinces. The specific name tetajulia refers to Las Tetas de Julia, a pair of prominent peaks on Monte Iberia, near the type locality of this species.
Physalaemus deimaticus is a species of frog in the family Leptodactylidae. It is endemic to Brazil and only known from its type locality in Jaboticatubas, Serra do Cipó, Minas Gerais. The specific name deimaticus is derived from Greek deimos fror "fear" and refers to the defensive display of this frog, probably aimed at scaring predators. Common names Jaboticatubas dwarf frog and frightening foam froglet have been coined for it.
Aphantophryne sabini is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea and is only known from the region of its type locality, Myola Guest House in the Owen Stanley Range, Northern Province. The specific name sabini honors Andrew E. Sabin, an American businessman, philanthropist, and environmentalist who joined the expedition during which the holotype of this species was collected. However, its vernacular name Guest House Guinea frog refers to the type locality instead.
Glyphoglossus minutus, also known as the minute narrow-mouthed frog, is a species of frog in the family Microhylidae. The specific name minutus alludes to the small size of this species. It is endemic to Peninsular Malaysia and only known from four localities in the state of Pahang: two inside the Taman Negara National Park, one in the Krau Wildlife Reserve, and Gunung Senyum. It probably occurs more widely in central Peninsular Malaysia.
Xenorhina bidens is a species of frog in the family Microhylidae. It is endemic to New Guinea and found between Lorentz River in the west and Fly River in the east, thus being present in both West Papua (Indonesia) and Papua New Guinea. Common name Digul River fanged frog has been coined for it, in reference to Digul River where the type series was collected in 1904 or 1905.
Petropedetes perreti is a species of frog in the family Petropedetidae. It is endemic to Cameroon. It is known from the southern slopes of the Bamiléké Plateau, Mount Manengouba, and Mount Nlonako. Common name Perret's water frog has been coined for it.
Phrynobatrachus parkeri is a species of frog in the family Phrynobatrachidae. It is endemic to the west-central and northeastern Democratic Republic of the Congo. It is only known from a few widely separated localities. It is similar to Phrynobatrachus acridoides(Cope, 1867), and it might be a synonym of the latter. The specific name parkeri honors Hampton Wildman Parker, an English zoologist and herpetologist. Common name Parker's river frog has been coined for it.
Strongylopus kilimanjaro is a species of frog in the family Pyxicephalidae. It is endemic to Tanzania and only known from a narrow alpine range on the middle slopes of Mount Kilimanjaro, within the East African montane moorlands ecoregion. It is known only from three specimens collected in 1936. The lack of recent records is probably a reflection of very limited survey effort in the area since then.
