Justification of Red List category
This species has a very small range, in which the extent and quality of its habitat are suspected to decline. The population is small and thought to form just one subpopulation. Nevertheless, the species cannot be considered severely fragmented or occurring at a limited number of locations, and there is insufficient data to infer a continuing decline in population size and habitat availability. Therefore, the species is listed as Near Threatened.


Population size: 2500-9999 mature individuals

Population trend: decreasing
