Scientific Name: Matoatoa spannringi Nussbaum, Raxworthy & Pronk, 1998

Assessment Information [top]

Red List Category & Criteria: Data Deficient B1ab(iii) ver 3.1
Year Published: 2013
Date Assessed: 2013-07-29
Assessor(s): Raxworthy, C.J., Ratsoavina, F., Rabibisoa, N., Rakotondrazafy, N.A., Bora, P. & Jenkins, R.J.
Reviewer(s): Bowles, P.
Justification:
Listed as Data Deficient on the basis that, while this species is known from only two localities, it has only been detected twice over a period of 15 years, and its recent rediscovery a considerable distance from the type locality suggests that this rare gecko could well be more widespread than is presently known. Although there is a continuing decline in the extent and quality of its apparent habitat at both known localities, its ecology is very incompletely known.

Geographic Range [top]

Range Description:

This gecko is endemic to southeast Madagascar where it was until recently known from a single locality, Fiadanana (Nussbaum et al. 1998), at 690 m asl. Although Fiadanana covers an area of approximately 117 km2, this species appears to be confined to specific microhabitats and may be confined to an area of less than 10 km2 at this locality. In March 2011, it was recorded from Sainte Luce, in far southeast Madagascar more than 350 km2 from Fiadanana (Funnell et al. 2012).

Population [top]

Population:This conspicuous, distinctive gecko may be one of the rarest reptiles in Madagascar (Funnell et al. 2012). The type series consisted of four individuals collected over a month of survey work. The only other record is of a single individual, collected in Sainte Luce 13 years after the species' description (Funnell et al. 2012). It is very likely to be declining at, or to have been lost from, Fiadanana as a result of land clearance.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:

In Fiadanana this species was found in degraded humid forest, where it was collected from inside holes in Weinmannia sp. trees (Nussbaum et al. 1998). The recent record from Sainte Luce was from an area of degraded, open-canopy forest with some evidence of logging (Funnell et al. 2012). In contrast to the Fiadanana records, this individual was recorded from the slender leaf of a species of Pandanus, the plant being 980 mm tall and much the same width (Funnell et al. 2012).

Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade:

There is no information to suggest that this species is traded or used.

Threats [top]

Major Threat(s): In Fiadanana, this gecko appears to rely on holes in a single genus of small and medium-sized trees (Nussbaum et al. 1998, Funnell et al. 2012) which are being cleared to make room for agriculture. It is thought unlikely to survive in the resulting agricultural habitats, and is absent from coffee plantations in the same area. Surveys at Fiadanana since the species' description have failed to record it, and it is possible that it has been lost from this locality. Forest in Sainte Luce is fragmented and under heavy pressure, and slow-growing Pandanus are vulnerable to exploitation.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place. Although Sainte Luce is protected as a reserve, forest loss and degradation are ongoing. The known localities are widely-separated, and targeted efforts are needed to conduct surveys for this lizard and to clarify its distribution, population status and ecological requirements.
