Although the range of this species has been extended considerably recently, it is still only known from five locations, and much of the intervening habitat is likely to be unsuitable. It occurs at a very low density and has highly specific habitat requirements, so it probably has a very small population. Habitat loss is ongoing within its range so it is likely to be declining. For these reasons it is listed as Endangered.
