Scientific Name:

Oryzorictes tetradactylus

Species Authority:

Milne-Edwards & A. Grandidier, 1882

Common Name/s:

English

–

Four-toed Mole Tenrec, Four-toed Rice Tenrec

Synonym/s:

Oryzorictes teradactylus Milne-Edwards & A. Grandidier, 1882 [orth. error]

Assessment Information [top]

Red List Category & Criteria:

Data Deficient ver 3.1

Year Published:

2008

Assessor/s:

Goodman, S., Jenkins, P. & Olson, L. (IUCN SSC Afrotheria Specialist Group - Tenrec Section)

Reviewer/s:

Rathbun, G. (Afrotheria Red List Authority) & Hoffmann, M. (Global Mammal Assessment Team)

Justification:
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status, threats and ecological requirements. Even though it is difficult to trap, the majority of specimens of this species were collected more than a hundred years ago.

History:

2006	–	Data Deficient (IUCN 2006)
1996	–	Lower Risk/least concern (Baillie and Groombridge 1996)

Geographic Range [top]

Range Description:	This species appears to be restricted to the south-central highlands and the flank of the eastern escarpment of Madagascar. It is only known from less than 10 sites, although it may be difficult to trap. It is found between 850 and 2,450 m asl.
Countries:	Native: Madagascar

Population [top]

Population:	There is no information on the population status of this species. It may be difficult to trap.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Appears to be largely confined to montane areas of the central eastern portion of the central highlands (only above the forest zone in Andringitra). It tends to occur in moist bottomland. It is semi-fossorial. There is nothing known about the ecology of this species, and it is not known if it can be found in modified habitats.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	The threats to this species are generally not known, and it may be that there are no major threats to the species. It occurs outside forested zones, and may be less affected by current levels of deforestation than many other species of forest-dependent small mammals.
