Cardioglossa pulchra is a species of frog in the family Arthroleptidae. It is found in the Cameroon Range in western Cameroon (excluding Mount Cameroon) and in the Obudu Plateau in adjacent eastern Nigeria. Common name black long-fingered frog has been coined for it. [1] [2]

Description

Males measure 23–33 mm (0.9–1.3 in) [3] [4] and females 31–34 mm (1.2–1.3 in) in snout–vent length. [3] Males have extremely long third fingers and spines in the fingers and in the groin; females lack these characteristics (though no female specimens of this particular species were inspected). [5] Dorsal markings, typical for the genus Cardioglossa, are fused to a broad black stripe that extends over the entire dorsum. [4] The white line running under the tympanum is absent. [3]

The tadpoles have a depressed, elliptical body and a long tail with broadly rounded tip. The largest specimen (Gosner stage 29) measures 25 mm (1.0 in) in total length, most of which is tail: body length is only 8 mm (0.3 in). [6]

Habitat and conservation

Cardioglossa pulchra occurs in submontane and montane forests along fast-flowing streams; at higher elevations it occurs also along forest edges. It tolerates some deforestation. Its altitudinal range is 900–1,800 m (3,000–5,900 ft) above sea level. Breeding takes place in streams. [1] Tadpoles have been found in a stream surrounded by farm bush vegetation, without any trees growing on the riverbanks. The tadpoles were found near the riverbank, hiding in the sandy mud or between stones. [6]

Cardioglossa pulchra can be common during the breeding season. The species is threatened by habitat loss caused by agricultural encroachment (including plantations of tree crops), expanding human settlements, and extraction of wood for firewood and building materials. It occurs in the Bafut-Ngemba Forest Reserve in Cameroon and in the Cross River National Park in Nigeria. [1]

<i>Cardioglossa</i> Genus of amphibians

Cardioglossa is a genus of frogs in the family Arthroleptidae known as long-fingered frogs. They are native to western and central Africa, with the greatest species richness in Cameroon. They are found near streams in lowland and mountain forests, but also occur in other highland habitats near streams at up to 2,700 m (8,900 ft) in altitude. These are small frogs with a snout-to-vent length of 2 to 4 cm (0.8–1.6 in). Some of the more localized species are threatened.

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.

Cardioglossa cyaneospila is a species of frog in the family Arthroleptidae. It is endemic to the Albertine Rift area in eastern Democratic Republic of the Congo, southwestern Uganda, Rwanda, and southwestern Burundi. It was described in 1950 by Raymond Laurent based on specimens collected in 1949. No new records were published until 2011. Recent research has uncovered both old unpublished records and several new records, and the conservation status was changed from "data deficient" to "near threatened" in 2016. Common names Bururi long-fingered frog and Mukuzira long-fingered frog have been coined for this species.
