Endangered.

Remarks

This species is sister to V. guanche , and is characterized by its uniform dark brown shell, with the occasional presence of lighter-colored spiral bands just as in the holotype. It has been synonymized with V. franciscanus in Petuch & Berschauer (2016) . However, according to the phylogeny, the latter is a distinct, valid species sister to V. guinaicus . In any case, the guinaicus clade is very compact, and all its members are closely related to each other.
