Assessment Rationale:

This species is endemic to the Canary islands, where it is found on area along the coast and southern slopes of the Anaga Mountains of Tenerife (North-east of Santa Cruz).  It has been assessed as Vulnerable as the species is not as impacted as H. pouchadan, which occurs around Santa Cruz, although should the rate of change of habitat decline or loss of subpopulations accelerate, the species will qualify as Endangered. The species requires protection of the habitat as well as restoration of habitats to lessen the impact of fragmentation.
