Cardioglossa oreas (common name: Mount Okou long-fingered frog [1] [2] [3] ) is a species of frog in the family Arthroleptidae. [1] [2] [4] It is endemic to Cameroon and known from the Western High Plateau between Mount Oku and the Bamboutos Mountains. [1] Records from Mount Manengouba refer to Cardioglossa manengouba . [1]

Description

Males measure 23–23 mm (0.9–0.9 in) and females 27–30 mm (1.1–1.2 in) in snout–vent length. [5] Unusually for the genus Cardioglossa, the third finger in males is not elongated. It is nevertheless sexually dimorphic in that males have spines in the fingers whereas females do not. [6] The tympanum is small and inconspicuous, another unusual character within Cardioglossa. [7] Furthermore, the characteristic dorsal markings and the white line running under the tympanum are absent. [5] Despite these unusual morphological characters, genetic data nest C. oreas well within the genus Cardioglossa. [6] [8]

Habitat and conservation

Cardioglossa oreas occurs in montane forests, often in bamboo forests; it also occurs in degraded habitats containing trees. It is typically found in areas around fast-flowing streams, its breeding habitat. Its altitudinal range is 1,900–2,650 m (6,230–8,690 ft) above sea level. [1]

Cardioglossa oreas is common within its small range, but the distribution of this species is severely fragmented and its forest habitat is declining. It occurs in the Bafut-Ngemba Forest Reserve. [1]

Arthroleptis is a genus of frogs in the family Arthroleptidae found in tropical sub-Saharan Africa. Their common names include screeching frogs, sometimes simply squeakers.

<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.

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.

<i>Arthroleptis carquejai</i> Species of frog

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.

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.
