The unsuccessful efforts to locate it at the original locality suggest that it is extinct, but the area has not received enough study to be certain of this. However, if not extinct, it is facing an extremely high risk of extinction in the immediate future. The area of occupancy might be less than 10km² in only one locality and the habitat is declining. It therefore meets the IUCN criteria for Critically Endangered based on the small area and the decline in habitat quality and extent.
