Xenopus boumbaensis, the Mawa clawed frog, is a predominantly to fully aquatic species of frog in the family Pipidae, [3] [4] [5] known from a few localities in central and southern Cameroon, the northwestern Republic of the Congo and the extreme southwest of the Central African Republic. The species likely occurs more widely throughout the Central African forest region, but identification is difficult [1] as it is a cryptic species, resembling Xenopus fraseri ; however, X.boumbaensis is distinguishable by chromosome number (2n=72) and the species' male advertisement call, consisting of a single note.

Etymology

The specific name boumbaensis refers to the type locality (Mawa) that is within the Boumba River drainage. [2] [3]

Description

Adult males can grow to 37 mm (1.5 in) and females to 53 mm (2.1 in) in snout–vent length. [6] All Xenopus are characterized by a streamlined and flattened body, a vocal organ specialized for underwater sound production, lateral-line organs, claws on the innermost three toes, and fully webbed toes. [6] The coloration is green with numerous spots posteriorly and on the hind limbs. The venter can be immaculate white but is often heavily spotted. [2]

Xenopus boumbaensis is an octoploid species (2n=72). [2] [6]

Habitat and conservation

This species occurs in aquatic habitats in the lowland rainforest region at elevations of 337–550 m (1,106–1,804 ft) above sea level. It is typically found in forested habitats in slow-flowing forest streams and springs, but may also be found in swamps. Reproduction presumably involves free-living larvae. It is threatened by deforestation and habitat degradation as well as water pollution. It is known from a number of protected areas: Boumba Bek, Nki, and Lobeke National Parks in Cameroon, Dzanga-Sangha Special Reserve in the Central African Republic, and the Odzala-Kokoua National Park in the Republic of Congo.

African dwarf frog is the common name for members of Hymenochirus, a genus of aquatic frog native to parts of Equatorial Africa. They are common in the pet trade and are often mistaken for the African clawed frog, a similar-looking frog in the same family. Their common name is obtained from their place of origin and the claws on their hind legs.

<i>Hymenochirus boettgeri</i> Species of frog

Hymenochirus boettgeri, also known as the Zaire dwarf clawed frog or the Congo dwarf clawed frog, is a species of frog in the family Pipidae. It is found in Nigeria, Cameroon, Equatorial Guinea, Gabon, and east to the Central African Republic and to eastern Democratic Republic of the Congo. It presumably occurs in the Republic of the Congo but has not been recorded there. It is a common species over most of its wide range and the International Union for Conservation of Nature has assessed its conservation status as being of least concern.

<i>Astylosternus batesi</i> Species of frog

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.

Afrixalus equatorialis, also known as the Congo banana frog, is a species of frog in the family Hyperoliidae. It is found in the central parts of the Congo Basin in the Democratic Republic of the Congo and south-eastern Cameroon, and is likely to be found in the Republic of the Congo and the Central African Republic as well. It might be conspecific with Afrixalus nigeriensis and is closely related to Afrixalus leucostictus.

<span class="mw-page-title-main">Lake Oku clawed frog</span> Species of amphibian

The Lake Oku clawed frog is a species of frog in the family Pipidae, endemic to Lake Oku, a small crater lake in northwest Cameroon. It is a small, dark-coloured, fully aquatic frog with a length of 28 to 36 mm, males being slightly smaller than females. The International Union for Conservation of Nature has rated this frog as "critically endangered" on the basis of its small area of occurrence at a single location, and the possibility that introduction of non-native fish into the lake could cause the frog to be wiped out.
