Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2018
Date Assessed: 2018-01-15
Assessor(s): IUCN SSC Amphibian Specialist Group

Listed as Vulnerable since this species occurs in a single threat-defined location and is thought to be endemic to the highlands. Ongoing development of the Genting Highlands may lead to increased habitat loss and degradation, which may pose a future threat to this species.

Geographic Range [top]

Range Description:This species is only known to occur in the upland regions of the Titiwangsa Mountain Range (at approximately 900 m asl) in Genting Highlands, Peninsular Malaysia (Davis et al. 2016). It is unknown whether this species occurs more widely, however it is believed to be an endemic to the highlands (Malaysia Red List Assessment Workshop January 2018).
Countries occurrence:
Malaysia (Peninsular Malaysia)

Current Population Trend:Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:This semi-aquatic species inhabits hilly montane tropical rainforest. Four of the specimens were found between 20:00 and 23:00 hrs in a small drainage ditch at the side of a dirt road, next to a muddy slope covered by hill dipterocarp forest. Five other specimens were found on top of the leaf litter, in a closed canopy forest (Davis et al. 2016). Both localities were in the vicinity (50–200 m) of a large, fast-flowing rocky stream with various side pools. The holotype and four of the paratypes were collected during the month of March, three of which were gravid indicating that March falls within this species’ reproductive season (Davis et al. 2016).
Systems:Terrestrial; Freshwater
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): In Genting Highlands - a large and expanding resort and entertainment complex - the continued construction of hotels and other developments represent a highly plausible near-future threat to species occurring within this area and is likely to affect the water quality of stream habitats (E. Quah pers. comm. January 2018).
