Assessment Rationale:

There are two known sites in one location and the area of occupancy is smaller than 10 km2, but there is no current major threat and no reason to suppose that the extent of occurrence, area of occupancy, quality of habitat, number of locations, number of sub-populations or the number or mature individuals are declining or extremely fluctuating. Therefore, it is assessed as Near Threatened (NT), almost meeting criteria B.
