Material examined

Holotype

CABO VERDE • 13.7 mm; São Vicente Island, Calhau ; 16º51ʹ7ʺ N, 24º51ʹ59ʺ W; MNCN exped.; MNCN 15.05/200008 ( Fig. 4C ).

Other material

CABO VERDE • 1 spec., 14.5 mm; same collection data as for holotype; 12 Apr. 2016; GenBank mitochondrion, partial genome: MF491601 ; MNCN 15.05/78562 .

Geographical distribution

From Calhau to Saragaça, southeast coast of São Vicente Island, Cabo Verde Archipelago.

Conservation status in IUCN Red List

Not evaluated.

Remarks

This small-sized species is morphologically similar to A. miruchae from Sal Island, and to A. denizi . Phylogenetic analyses show that A. freitasi , A. denizi and A. miruchae are distinct species despite their partial similarity in shell morphology. The phenotypic resemblance of the shell of A. freitasi to A. miruchae is possibly the result of convergence, whereas the similarity to A. denizi may reflect their close phylogenetic relationship, sharing a relatively recent last common ancestor.
