Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA MICROHYLIDAE

Scientific Name: Plethodontohyla fonetana
Species Authority: Glaw, Köhler, Bora & Rabibisoa, 2007

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2009
Date Assessed: 2009-07-27
Assessor(s): Vences, M., Andreone, F., Rabibisoa, N.H.C. & Cox, N.
Reviewer(s): Hoffmann, M. & Angulo, A.
Justification:
Listed as Endangered because its overall extent of occurrence is predicted to be less than 5,000 km², its habitat and distribution are severely fragmented, and there is continuing decline in the extent and quality of its forest habitat.
History:
2008 Vulnerable (IUCN 2008)
2008 Vulnerable

Geographic Range [top]

Range Description: This species is known only from Bendrao Forest, at 420-470 m asl, in the Tsingy de Bemaraha National Park, Mahajanga Province, western Madagascar. It appears to be endemic to the low-elevation dry forest of the Tsingy de Bemaraha.

Population [top]

Population: It is known from only two specimens. Attempts to locate the species, using pitfall traps in three other sites in the Tsingy de Bemaraha National Park, failed to capture any additional specimens, so it appears to be rare.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Very little information is available on this species. It has been found in moderately moist dry forest among "tsingy" rocks. One specimen contained more than 100 eggs, indicating that the specimen was ready for reproduction at the end of the rainy season. Its stomach contained a large number of medium-sized insect remains (ants, beetles) and pieces of dead leaves from the forest floor. Both specimens were found in the same forest (Bendrao), but the actual range is likely to comprise a larger area. However, it is probably endemic to the Tsingy de Bemaraha massif due to the absence of sufficient humidity outside the karstic habitats elsewhere in the general region.Its breeding is not known, but it is probably a terrestrial, larval developing species, not requiring water, like some other members of the genus.
Systems: Terrestrial

Use and Trade [top]

Use and Trade: There is no information on the uses of this species. It is not collected for the international pet trade.

Threats [top]

Major Threat(s): The Bendrao forest has been degraded by zebu (cattle) grazing. It is possible that other dry forest habitats potentially inhabited by this species in the Tsingy de Bemaraha have also been degraded by overgrazing, and firewood or timber collection.

Conservation Actions [top]

Conservation Actions: It occurs in the Tsingy de Bemaraha National Park where there is a need to limit additional habitat degradation, especially in the Bendrao Forest. Research is needed to determine the limits of its distribution, and its ecological requirements.
