Other material

CABO VERDE • 1 spec.; São Vicente Island, Calhau ; 16º51ʹ7ʺ N, 24º51ʹ59ʺ W; 12 Apr. 2016; MNCN exped.; GenBank mitochondrion, partial genome: MF491600 ; MNCN 15.05/78557 .

Geographical distribution

Southeast coast São Vicente Island, Cabo Verde Archipelago.

Conservation status in IUCN Red List

Near threatened.

Remarks

This small, distinctive species with a very restricted distribution range belongs to a lineage that includes species endemic to the westernmost islands in the Cabo Verde Archipelago. It is sister to A. fernandesi from Santo Antão Island, and to the pair A. curralensis / A. insulae from Santa Luzia. It is only distantly related to A. calhetae from Maio Island, which was initially introduced as a subspecies of A. navarroi due to similarities in shell morphology, now considered convergent.
