Material examined

Lectotype

Representation of lectotype in Martini (1773: pl. 60, fig. 669) ( Kohn 1975). Type locality not stated, designated Villa Cisneros (now Dakhla), Western Sahara ( Coomans et al. 1982) .

Other material

MAURITANIA • 1 spec., 56.4 mm; Noadibou; MNCN 15.05/90429 ( Fig. 6O ) .

Geographical distribution

Western Sahara and Mauritania.

Conservation status in IUCN Red List

Not evaluated.

Remarks

Specimens from the type locality have not been molecularly examined. However, the mitogenome of a specimen from Senegal with a shell morphology matching that of typical K. byssinus is almost identical to that of K. pulcher ( Abalde et al. 2017a) . There are no significant differences between the radular teeth of K. pulcher and K. byssinus . Although we consider K. byssinus as provisionally valid only, pending molecular examination of specimens from the type locality, it is however likely that this taxon represents just a phenotypic variation of the widespread K. pulcher , typical of the northern end of its distribution range along the West African coast.
