The IUCN reports that this taxon is "vulnerable." It has a very restricted area of occupancy (typically less than 20 km2) or number of locations (only two are known) such that it is prone to the effects of human activities or chance events within a very short time period in an uncertain future, and is thus capable of becoming Critically Endangered or even Extinct in a very short time period. This assessment was performed in 1998 and needs updating.
