Cardioglossa oreas

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]
