Treatment

Alycaeus kapayanensis de Morgan, 1885b: 403, pl. 8, fig. 5.

Alycaeus (Orthalycaeus) kapayensis (sic) - Möllendorff 1891: 342.

Alycaeus (Alycaeus) kapayanensis - Kobelt 1902: 346.

Alycaeus kapayanensis - Foon and Liew 2017: 46-49, figs 7O, 20, 31M.

Type locality.

"rochers calcaires du G. Lano".

Material examined.

G. Laon, Perak, MNHN-IM-2000-31792 (1 syntype).

Remarks.

Protoconch extremely finely granulated, matte; R1 rather irregularly, finely ribbed with weaker spiral striation; R2 short, with alternating darker/thicker and lighter/slimmer stripes, which are somewhat elevated from the surface, the whole area is rather irregularly sculptured.

Foon and Liew (2017) described six new species from Peninsular Malaysia, which are similar to S. kapayanensis in all the important characters, and show only minor differences, such as fine sculpture (e.g., strength of radial vs. spiral striation), operculum thickness, and shell size and shape. Here we maintain those species ( alticola , charasensis , costacrassa , ikanensis , kurauensis , selangoriensis and virgogravida ) as subspecies of S. kapayanensis .
