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]
