This species is endemic to southern Gran Canaria. It has a restricted range and is impacted by the increasing tourist and urban development in the area. It is therefore considered as Near Threatened (NT), almost meeting criteria B.

Geographic Range:

This species is endemic to southern Gran Canaria where it is said to be from the Pinar near San Bartholome and the lowlands near El Charco near Maspalomas, Aguineguin Lowe (1861). Neiber et al. (2011) gives detailed genetic analysis of two specimens from Telde: Barranco de Pueste and San Bartholome de Tirajana: Monte Leon, which has not re-discovered or mentioned by Ibanez and his colleagues but has been found by Klaus Groh in the environments of Telde (K. Groh, pers. com., 2011). The extent of occurrence is estimated to be 100 km² and the area of occupancy is actually less than 20 km².
