Material examined

Holotype

CABO VERDE • 38.6 mm; Sal Island, Serra Negra ; 16º38ʹ16.5ʺ N, 22º53ʹ56ʺ W; 1–3 m depth; 5 Apr. 2014; MNCN exped.; GenBank mitochondrion, partial genome: MF491568 ; MNCN 15.05/79664 ( Fig. 9C ).

Other material

CABO VERDE • 1 spec.; Sal Island, Rabo de Junco ; 16º41ʹ44ʺ N, 22º58ʹ35ʺ W; 6 Apr. 2014; MNCN exped.; GenBank mitochondrion, partial genome: MH243427 ; MNCN 15.05/79687 • 1 spec., 36.6 mm; same collection data as for preceding; GenBank mitochondrion, partial genome: MH243428 ; MNCN 15.05/79689 ( Fig. 9D ) .

Geographical distribution

Conservation status in IUCN Red List

Not evaluated.

Remarks

This recently described species was formerly identified as K. venulatus or K. ateralbus . Kalloconus venulatus is absent from Sal Island, and K. ateralbus has enough mitogenome sequence divergence to be considered a separate species, sister to K. marimaris (see above). The latter is split into two populations inhabiting areas to the east and west coasts of Sal Island. This species has some morphological similarities to K. ateralbus and hence the confusion. Kalloconus marimaris is very variable in background color, with yellow, orange, milky white or brown morphs, whereas in K. ateralbus the background color is always black.
