Hyperolius obstetricans, or frilled egg-guarding frog, is a species of frog in the family Hyperoliidae. [2] [3] It is known from southern and south-western Cameroon, Equatorial Guinea, Gabon, [1] [2] [3] and northern Angola; [2] [3] it is likely to occur in the intervening Republic of the Congo and Democratic Republic of the Congo.

Description

Hyperolius obstetricans grow to 31 mm (1.2 in) in snout–vent length. The body is slender while the head is broad with a rounded snout. The eyes are large. The tympanum is distinct. The finger and toe tips are enlarged into large, rounded discs; the fingers have medium webbing while the toes have almost complete webbing. Dorsal skin is granular. The dorsum is blueish green-grey, grass- or olive-green to brownish green with many minute white dots and possibly with some darker markings on the head and shoulders; the region from the eyelids to the nostrils is brownish. Skin is ventrally finely granular. The anterior part of the throat is white while the posterior part is dark blue in males and turqoise in females. The belly is translucent turquoise to black, with the inner organs visible through the skin. [4]

The male advertisement call is a slow, metallic "tuc" that is repeated 5–6 times. [4] [5]

Habitat and conservation

Hyperolius obstetricans occurs in forests at elevations below 800 m (2,600 ft) in association with narrow streams under continuous canopy. Its favoured streams have well-aerated, flowing, but not torrential water. The eggs are laid in small clumps on leaves above streams, into which the tadpoles fall and develop further. It is a common but patchily distributed species that is often absent from apparently suitable habitat. It is probably threatened by loss of closed-canopy forests. It is present in the Moukalaba-Doudou National Park (Gabon) and probably in some other protected areas too. [1]

<i>Hyperolius poweri</i> Species of amphibian

Hyperolius poweri is a species of frogs in the family Hyperoliidae. It is found in southeastern coast of South Africa and southern Mozambique. The specific name poweri honours John Hyacinth Power, Irish-born director of the McGregor Museum who collected amphibians as well as reptiles and plants. Accordingly, common names Power's reed frog and Power's long reed frog have been proposed for this species.

Hyperolius discodactylus is a species of frogs in the family Hyperoliidae. It occurs in the montane areas of eastern Democratic Republic of the Congo and western Uganda, Rwanda, and Burundi. It is also known as the Albertine Rift reed frog, highland reed frog, or disc-fingered reed frog.

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.

It is found in southwestern Cameroon, Gabon, and Equatorial Guinea and eastward to the central Democratic Republic of the Congo; it probably occurs in northern Republic of the Congo and the Central African Republic too. It is also reported from Uganda, but the status of this population is unclear. The specific name kuligae honours Paul Kuliga (1878–1948), a physician who joined an expedition to Cameroon in 1936. Common names Camp Kivu reed frog and Kuliga reed frog have been proposed for it.

<i>Hyperolius nasutus</i> Species of frog

Hyperolius nasutus is a species of frog in the family Hyperoliidae. Common names include long-nosed reed frog, sharp-nosed reed frog and long reed frog. It is known from northern Angola and northern Botswana, but it presumably occurs more widely. The nominal Hyperolius nasutus was partitioned in 2013 into three cryptic species, the other two being Hyperolius viridis and Hyperolius microps. All these species are members of the so-called Hyperolius nasutus species group, the "long reed frogs".

<i>Hyperolius ocellatus</i> Species of amphibian

Hyperolius ocellatus is a species of tropical West African frog in the family Hyperoliidae, that is split into the subspecies H. o. ocellatus and H. o. purpurescens. It is found in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon, Nigeria, Uganda, and possibly Rwanda. Its natural habitats are subtropical or tropical moist lowland forests, rivers, intermittent freshwater marshes, freshwater springs, rural gardens, heavily degraded former forest, ponds, and canals and ditches.

<i>Hyperolius parallelus</i> Species of frog

Hyperolius parallelus, also known as the Angolan reed frog, is a species of frog in the family Hyperoliidae. It is found in Southern and Central Africa. It is part of the so-called Hyperolius viridiflavus species complex and has a complex history of taxonomic treatments.

Hyperolius pseudargus, also known as the Mette's reed frog, is a species of frogs in the family Hyperoliidae. It is endemic to south-central Tanzania and occurs in the Udzungwa Mountains and south to Njombe in the Southern Highlands. Male Hyperolius pseudargus greatly resemble Hyperolius argus but have less webbing between the toes and the male advertisement call is different. The vernacular name refers to Mette Westergaard, Danish biologist who collected the holotype and is the junior describer of this species.

Hyperolius schoutedeni is a species of frog in the family Hyperoliidae. It is known from the northern half of the Democratic Republic of the Congo, central-west and southeastern Republic of the Congo, and southeastern Gabon; its true range probably extends into the adjacent Central African Republic and South Sudan. It is morphologically very similar to Hyperolius cinnamomeoventris and has been confused with that species. However, molecular data suggests that its closest relatives include Hyperolius kivuensis, Hyperolius balfouri, and Hyperolius quinquevittatus, rather than H. cinnamomeoventris.

Leptopelis crystallinoron is a species of frog in the family Arthroleptidae. It is endemic to Gabon and only known from the area its type locality near the Barrage de Tchimbélé in the central Monts de Cristal. Only one specimen was known until five specimens were captured in the Crystal Mountains National Park in 2009. It is probable that this species is endemic to the Monts de Cristal and that its range extends into Equatorial Guinea.

Opisthothylax is a monotypic frog genus in the family Hyperoliidae. The sole species is Opisthothylax immaculatus, also known as the gray-eyed frog . It is found in southern Nigeria, Cameroon, Equatorial Guinea, Gabon, western Republic of Congo, and southwestern Democratic Republic of the Congo. It might also be present in the Cabinda Enclave of Angola and in the Central African Republic.
