Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Jean-Louis Amiet, Arne Schiøtz
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area Of Occupancy is less than 10km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat in the Rumpi Hills.

Geographic Range [top]

Range Description:This recently described species is known only from two localities at 800-1,050m asl, 6km apart near the villages of Betenge and Mofako on the eastern slopes of the Rumpi Hills in south-western Cameroon. It might occur a little more widely, but appears to be absent from other sites that have been explored nearby.

Current Population Trend:Decreasing

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is associated with narrow streams in forests, over which there is a continuous canopy. It favours well aerated, flowing water, but avoids torrents. Males call close to streams in dense vegetation, and they presumably breed in a similar manner to Alexteroon obstetricans (i.e., small clumps of eggs are laid on leaves above streams, into which the larvae fall, and develop).
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Severe forest loss is taking place in the Rumpi Hills due to smallholder farming activities, logging, and human settlement.

Conservation Actions [top]

Conservation Actions: It is not known whether or not this species occurs in any protected area, though it might well occur in the Rumpi Hills Forest Reserve; habitat protection is a matter of urgent priority for this species. Survey work is also required to determine the current population status of this species and the limits of its range.
