Population justification: The species is now known from many sites in southern Vietnam and one in Cambodia. The area of suitable habitat has been found to be more extensive than was previously thought and given the population densities recorded in several congeners and their ability to persist in degraded habitats it seems likely that the population approaches 10,000 individuals, and it is thus placed in the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: This species is assumed to have declined owing to clearance within its very small range, but it is probably tolerant to some degree of forest degradation. Declines are thought to be continuing as forest clearance continues.
