Bencomia sphaerocarpa is endemic to the island of El Hierro, Canary Islands, Spain (MartÃn Osorio et al. 2004), where it can be found on the northern side of the island, from 400 to 1,200 m asl, in three locations: Tinco, Hoya de Fileba and TÃ¡bano. Only one of them shows an acceptable degree of conservation. The presence of the species in the island of La Palma has been reported in the past, but it has not been recently confirmed.
The area of occupancy of the species has been calculated to be between 0.75 and 3 km2. Decreasing trends have been reported for the distribution of the species (Gobierno de Canarias 2004).
