Arthroleptis bioko, the Bioko squeaker frog, is a species of frog from the genus Arthroleptis . It is native to Equatorial Guinea. The species was scientifically described in 2010 by Blackburn. It is listed as Endangered on the IUCN Red List.
The species is a medium-sized frog with a relatively thin head. The eyes have a spherical pupil and protrude somewhat from the eyelids on the sides of the head. On the sides of their bodies, they have skin ridges, and on the back and sides of their bodies, they have little, spiky projections. The species is entirely described from male specimens measuring between 26.7 to 33.4 mm (1.05 to 1.31 in). The third digit on the front limbs, which have four digits total, is the longest. The fourth finger on the hind limbs, which have five digits total, is the longest. The toes and fingers have broad, rounded tips, and there is no webbing between the digits. The species is generally grayish-brown in color. The dorsal side of the frog has a few distinct deeper brown markings and blotchy areas of light-brownish gray. The tympanum is dark and hardly translucent. There is no colour on the tips of the fingers and toes. In addition to having a longer third finger, males also have spiny projections on their toes and crotch. They also have stretched and darker-colored skin around their throats. Both the pupil and iris are gray. [2] [3]
The species is endemic to Equatorial Guinea in about one to four locations. They are found in elevations around 1,321 to 1,820 m (4,334 to 5,971 ft). They are listed as Endangered on the IUCN based on their declining population, though much is not known in that regard. Climate change could be another reason for the decline in populations. [1]
It lives in forests of Bioko in leaf litters. They are also spotted near water sources like streams. Not much is known about the disturbance tolerance of the species or its secondary habitat. Human encroachment could be a possible threat to the species rather than habitat loss. [3]
Arthroleptis adolfifriederici is a species of frog in the family Arthroleptidae. It is found in the eastern Democratic Republic of the Congo, Rwanda, Burundi, and Uganda. Several common names have been coined for it, including Rugege Forest squeaker, Rugegewald squeaker, Adolf Friedrich's squeaker frog, and Adolf's squeaker.
Arthroleptis bivittatus is a species of frog in the family Arthroleptidae. It is endemic to Guinea and only known from the holotype collected from the Tombo Island. It is uncertain whether this species is distinct from the common Arthroleptis poecilonotus. Common name Tumbo-Insel screeching frog has been coined for this species.
Arthroleptis carquejai is a species of frog in the family Arthroleptidae. It is known with certainty only from north-western Angola, but there is also a recent record from Gabon. If this is correct, its distribution might also include intervening areas in the Republic of the Congo and the Democratic Republic of the Congo. The specific name carquejai honours Bento Carqueja, Portuguese professor, journalist, and philanthropist. The common names Cambondo screeching frog and Carqueja's squeaker have been proposed for it.
Arthroleptis francei is a species of frog in the family Arthroleptidae. It is found in Mount Mulanje in southern Malawi and in Mount Namuli and Mount Mabu in northern Mozambique. Records from the Zomba Massif (Malawi) require confirmation. Common names Ruo River screeching frog and France's squeaker have been coined for it.
Arthroleptis lameerei is a species of frog in the family Arthroleptidae. It is found in northeastern Angola, southeastern Democratic Republic of the Congo, and western Burundi, though the exact range is poorly known. There is some doubt whether it is distinct from Arthroleptis xenochirus. The specific name lameerei honours Auguste Lameere, a Belgian entomologist. Common names Lameere's squeaker, Lameer's squeaker, and Katanga screeching frog have been coined for this species.
Arthroleptis nikeae, also known as Nike's squeaker, is a species of frogs in the family Arthroleptidae. It is endemic to the Mafwemiro Reserve in the Rubeho Mountains of Tanzania. It was named after conservationist Nike Doggart, who first found it. With a maximum snout–vent length of 57 mm (2.2 in), it is among the largest Arthroleptis species.
Arthroleptis poecilonotus is a species of frog in the family Arthroleptidae. This adaptable species has a wide range within the Sub-Saharan Africa and is not considered threatened.
Arthroleptis reichei is a species of frog in the family Arthroleptidae. It is found in the mountains of eastern and southern Tanzania and northern Malawi. It has several vernacular names: Poroto screeching frog, large-toad squeaker, Poroto Mountains screeching frog, and Reiche's squeaker. The specific name reichei honours Karl Friedrich Reiche, a German botanist.
Arthroleptis tanneri, the Tanzania screeching frog or Tanner's squeaker, is a species of frog in the family Arthroleptidae. It is endemic to the West Usambara Mountains in northeastern Tanzania; previous records from elsewhere refer to other species.
The cave squeaker is a species of frog in the family Arthroleptidae. It is endemic to the Chimanimani Mountains in Zimbabwe.
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 oreas is a species of frog in the family Arthroleptidae. It is endemic to Cameroon and known from the Western High Plateau between Mount Oku and the Bamboutos Mountains. Records from Mount Manengouba refer to Cardioglossa manengouba.
Cardioglossa schioetzi is a species of frogs in the family Arthroleptidae. It is found in the mountains of Cameroon and eastern Nigeria. Specifically, it has been recorded from the Oshie-Obudu Range, Gotel Mountains, Mount Oku, and Mount Mbam. It is a generally poorly known species.
Astylosternus batesi is a species of frog in the family Arthroleptidae. It is found in Cameroon south of Sanaga River, Equatorial Guinea, Gabon, southwestern Central African Republic, the Republic of the Congo, and the extreme western Democratic Republic of the Congo (Mayombe). The specific name batesi honours George Latimer Bates, an American naturalist. However, its vernacular name is Benito River night frog, apparently in reference to its type locality, Benito River in Equatorial Guinea.
Petropedetes newtonii is a species of frog in the family Petropedetidae. It is found in the island of Bioko and in coastal Cameroon. It has been confused with Petropedetes vulpiae and Petropedetes johnstoni, and also considered a synonym of the latter. Because the holotype of Petropedetes newtonii is lost, a neotype was designated in 2018. Common name Newton's water frog has been coined for it.
Phrynobatrachus calcaratus, the Boutry river frog or Peters' puddle frog, is a species of frog in the family Phrynobatrachidae. It is widely distributed in West Africa and Middle Africa. However, this nominal species is a species complex consisting of several species.
Papurana supragrisea is a species of true frog, family Ranidae. It is endemic to New Guinea, including some nearby islands. It is known with certainty only from southeastern New Guinea and from the D'Entrecasteaux Islands. However, this name has been used more broadly for a species complex that is widely distributed in the mountains of New Guinea. Common name Papua gray frog has been coined for it.
Phrynobatrachus africanus is a species of frog in the family Phrynobatrachidae. It is found in Cameroon, Gabon, Equatorial Guinea, southwestern Central African Republic, western Republic of the Congo, and north-central Democratic Republic of the Congo. Its range might extend into Nigeria. The IUCN SSC Amphibian Specialist Group, however, considers the limits of its range unknown and does not include the Democratic Republic of the Congo in the range.
Arthroleptis kutogundua, also known as the overlooked squeaker frog, is a species of frog in the family Arthroleptidae. It has not been seen since 1930, and is believed to be possibly extinct.
Arthroleptis palava, also known as the problem squeaker frog or simply problem squeaker, is a species of frog in the family Arthroleptidae. It is found in the highlands of northern Cameroon and eastern Nigeria. The specific name palava is a Central/West-African pidgin word meaning "problem" and alludes to the past confusion of this species with the morphologically similar Arthroleptis poecilonotus.
