Taxonomy [top]

Kingdom	Phylum	Class	Order	Family
ANIMALIA	CHORDATA	AMPHIBIA	ANURA	BUFONIDAE

Scientific Name:	Ansonia malayana
Species Authority:	Inger, 1960
Taxonomic Notes:	This taxon is likely to be a complex of more than one species, and further comparisons of specimens from Peninsular Thailand and Peninsular Malaysia are required. The northernmost opulations of Peninsular Thailand are provisionally attributed to Ansonia malayana (see Inger, 1960), though they might in fact belong to A. siamensis (L. Grismer pers. comm.).

Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2004
Assessor/s:	Peter Paul van Dijk, Yodchaiy Chuaynkern, Jeet Sukumaran, Norsham Yaakob, Leong Tzi Ming, Lee Grismer
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification: Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:	This species is reported from much of Peninsular Malaysia, and Yala province to Chumphon, Thailand. It probably occurs more widely than current records suggest, especially in areas between known sites. It is also present on Phuket Island, Thailand. It is found at altitudes between 300 and 1,300m asl.
Countries:	Native: Malaysia; Thailand

Population [top]

Population:	It appears to be locally common in Peninsular Malaysia, but is uncommon in Peninsular Thailand.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It is associated with lowland and montane tropical moist forests. Adults are often encountered in boulder crevices and leaf-litter in streams. Breeding takes place in these streams where the larvae also develop. It has been recorded in selectively logged forest after three years of regrowth.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	It is only threatened by possible future clear cutting of forest habitat. Siltation of forest streams might threaten larval habitat.

Major Threat(s):
