DESCRIPTION
No information on the population size and trends of this species is known except that the species was described from 23 adult and two larval individuals, and that between one and nine individuals have been observed at a single locality on the same day (Wilkinson et al. 2012). Due to ongoing habitat degradation and loss it is reasonable to suspect that the population is decreasing.

Habitat and Ecology in detail
HABITAT AND ECOLOGY
This species is associated with the rocky edges of permanent streams within semi-evergreen forest. Adults remain hidden under stones during the day. Tadpoles inhabit submerged stones within the streams (Wilkinson et al. 2012). Much of the species ecology and most of its reproductive biology remain unknown.

Threats
Biological resource use
Logging & wood harvesting
Threats in detail
THREATS
The habitat at the Me Kyauklonegyi Stream in Tanintharyi Nature Reserve is relatively undisturbed, however deforestation is a continuous threat throughout the region and may affect this species (G. Wogan pers. comm. March 2015).

CONSERVATION ACTIONS
The species in known from Tanintharyi Nature Reserve (Wilkinson et al. 2012). Little is known about the species and conservation decisions would be better informed by further research into its range and relative abundance. |
