Justification of Red List category
This species is known from a few sites in a region where the environment is highly modified and habitat degradation is apparently continuing (Collar et al. 1992). Its known population is extremely small and likely to be declining, and all subpopulations are smaller than 50 individuals. This combination of factors leads to its classification as Critically Endangered.
