Geographical distribution

Senegal, Gambia, Guinea-Bissau, and Guinea. Also reported from Ghana.

Conservation status in IUCN Red List

Vulnerable. Status revision required.

Remarks

This is the most representative taxon of a very compact clade, which includes a number of very closely related species, and certain populations with minimal differences in mitogenome sequences that are now considered synonyms (forms), such as taslei   or pineaui   ( Fig. 10O View Fig ). All these taxa share the same radular tooth morphology: narrow and elongated radular tooth with the anterior section longer than the posterior section, rounded blade covering less than half of the anterior section, and more than 40 denticles in the serration ( Abalde et al. 2017b). The population from Gorée Island, characterized by its dark brown shell, does not correspond to the taxon guinaicus   but to its sister species V. franciscanus   . The distribution range of V. guinaicus   is quite large, from Dakar area south to Guinea including Gambia, and also reported from Ghana. The taxon V. wolof   ( Fig. 10N View Fig ), recently described from Gambia, has been sequenced. The sequence of its mitogenome is essentially identical to that of V. guinaicus   ( Fig. 2 View Fig ). Therefore, this name represents a mere local form of V. guinaicus   and is hereby considered a synonym.
