Geographical distribution

Between Calheta and Baía do Navío Quebrado, in the western and northwestern coast of Maio Island, Cabo Verde Archipelago.

Conservation status in IUCN Red List

Least concern.

Remarks

This taxon was initially introduced as a subspecies, i.e., Conus navarroi calhetae Rolán, 1990 , due to morphological similarities in shell and radula between the populations from São Vicente and Maio islands. However, these disjunct populations are genetically distant. The closest relative according to the phylogeny is the parapatric taxon A. galeao .
