Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA HYPEROLIIDAE

Scientific Name: Alexteroon jynx
Species Authority: Amiet, 2000

Assessment Information [top]

Red List Category & Criteria: Critically Endangered B1ab(iii)+2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Jean-Louis Amiet, Arne Schiøtz
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
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.

Population [top]

Population: There is no available information on its population status.
Population Trend: Decreasing

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.
