More information on the distribution, biology, population size and trends, and the current and potential threats to this species is needed.

Location Information

This species is highly restricted and known to occur from peat swamp habitats in the Bebar and Sedili river drainages in the southern Malay Peninsula (Ng and Lim 1993). Based on all available suitable habitat, Extent of Occurrence (EOO) and Area of Occupancy (AOO) is estimated at 44 km2. Additionally, three sampling attempts in 2018 failed to detect this species across its known range (A. Ahmad pers. comm. 2019).

Geographic Range

Possibly Extinct


Population Information

There is no information available on the population and its trend for this species, although Ng and Lim (1993) note that this species may no longer be present in the Sedili River drainage. The Bebar locality is likely incapable of supporting this species due to development and heavy sedimentation (A. Ahmad pers. comm. 2019) Additionally, peat swamp habitat has been declining at a considerable rate due to land development (Yule 2010, Miettinen et al. 2011), which may result in an inferred decline in number of mature individuals present. It is thought to be possibly extinct.


Although the current threats to aquatic biodiversity in all of its known distribution have not been adequately identified, the greatest threat to this species are the loss of blackwater peat swamps due to logging, plantation agriculture (Yule 2010, Miettinen et al. 2011), and urban development (A. Ahmad pers. comm. 2019), given this is an obligatory peat swamp species.
