Conservation status in IUCN Red List

Least concern.

Remarks

The type locality for this species is most likely erroneous, as it seems to be endemic to Santiago Island, being particularly abundant around the Tarrafal area to the northwest. The species introduced under the name nelsontiagoi had been illustrated and referred to as Conus cuneolus form M in Röckel et al. (1980a). This form appears distributed mostly along the east coast of Santiago Island, with a transition area to the north where it intergrades with typical A. verdensis . Morphological studies of shell and radula had already suggested the close relationship of this morph with the taxon A. verdensis ( Rolán 2005) . The molecular phylogeny and mitochondrial genome sequence divergences support the conspecificity of nelsontiagoi with A. verdensis .
