CABO VERDE • 22.8 mm; Maio Island, Baía de Pau Seco ; C.M.L. Afonso leg.; MNCN 15.05/46654 ( Fig. 4J ).

Other material

CABO VERDE • 1 spec.; Maio Island, Ponta de Pau Seco ; 15º15ʹ26ʺ N, 23º13ʹ17ʺ W; 29 Mar. 2013; MNCN exped.; GenBank mitochondrion, partial genome: MF491538 ; MNCN 15.05 /78850 .

Geographical distribution

West and northwest of Maio Island, Cabo Verde Archipelago.

Conservation status in IUCN Red List

Least concern.

Remarks

Africonus isabelarum , endemic to Maio Island, was initially considered conspecific with A. decoratus from São Vicente and Santa Luzia, due to similarities in shell pattern ( A. decoratus form C in Röckel et al. 1980a). In the phylogeny, it stands alone, sister to a large clade comprising many species distributed in Boa Vista and Maio islands, and only distantly related to A. decoratus .
