Geographical distribution

Multiple localities around Boa Vista Island, Cabo Verde Archipelago.

Conservation status in IUCN Red List

Least concern.

Remarks

This species is widely distributed around Boa Vista Island, with a high variability in shell pattern. This polymorphism has led to the introduction of several taxa names associated with certain populations, which are all considered synonyms hereby. Thus, the holotypes of A. diegoi and A. roquensis exhibit all the shell features characteristic of A. damottai (just a more elongated shell shape in the case of A. diegoi , which does not justify separation at the species level). The holotype of A. purvisi most likely represents a juvenile specimen of A. damottai , whereas the holotype of A. pinedensis resembles certain variations of A. damottai with a well-developed color pattern (i.e., Monteiro et al. 2004: pl. 89). The taxon A. galeao from Maio Island was initially introduced as a subspecies of A. damottai . Despite the morphological similarities in shell pattern and radular tooth, the phylogenetic analyses indicate that A. galeao can be regarded as a separate, valid full species.
