The only known published location is in Bank et al. (2002) at Barranco Argaga near Vallehermoso. There are no known threats, however, this site has not been re-discovered since. Therefore, it is assessed as Data Deficient (DD), until the locality can be re-discovered.
This species was described by Lamarck (1816) from “Porto-Rico” due to Maugé’s given data (Mermod 1951) and as Helix villiersi by d’Orbigny in 1839 as an endemic La Gomera species. The status of H. planorbella as the elder name was later rectified by L. Pfeiffer (in Mon. Hel. IV and Novitates I). There were no details on the distribution given. The only known published location is in Bank et al. (2002) at Barranco Argaga near Vallehermoso. However, this site has not been re-found or mentioned by Ibanez and his colleagues, nor found by Klaus Groh (K. Groh, pers. com., 2011).
There is no information on population trend.
There is no information on the species' habitat preferences.
Any threats to this species are unknown.
Research is recommended to attempt to re-discover the population mentioned in Bank et al. (2002). If this site is re-discovered conservation actions may be required if the site is at risk, unless further sites are found.
