Material examined

Holotype

CABO VERDE • 17 mm; Santa Luzia Island , Curral; 1–3 m depth; E. Rolán leg.; MNCN 15.05/1010 ( Fig. 3J ).

Other material

CABO VERDE • 1 spec., 23 mm; Santa Luzia Island , Curral; 16º46ʹ23ʺ N, 24º47ʹ13ʺ W; 14 Apr. 2016; MNCN exped.; GenBank mitochondrion, partial genome: MT240806 ; MNCN 15.05/78591 ( Fig. 5K ) .

Geographical distribution

Southwest coast of Santa Luzia Island, Cabo Verde Archipelago.

Conservation status in IUCN Red List

Near threatened.

Remarks

It was initially reported in Röckel et al. (1980a) as Conus decoratus form D. In the phylogenetic tree, it belongs to the same clade as A. decoratus , but appears only distantly related. A distinctive color form living sympatrically in Santa Luzia Island was initially confused with this species in Abalde et al. (2017a). The sequencing of a specimen fully matching the holotype of A. curralensis has shown that the alleged color form is actually a separate, sister species that is introduced hereby with the name Africonus insulae sp. nov. (see below).
