Justification of Red List category
This species is Endangered because remaining populations are very small, severely fragmented and, given continuing threats, presumably declining (Collar et al. 1992). Further surveys may find this species to be more widespread than recent records suggest, but effective protection of known sites is required if its conservation status is genuinely to improve.
