Justification of Red List category

Although the species has a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion which also requires a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation. The population trend is suspected to be stable, and hence does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified; hence it does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
