Assessment Rationale:

This species is endemic to the north of the island of La Palma. The range of this species is very restricted, with an extent of occurrence of  100 km2 and an area of occupancy of 4 km2. There are four known locations, but there is no current major threat and no reason to suppose that 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, almost meeting criteria B.
