Treatment

Alycaeus balingensis Tomlin, 1948: 224-225, pl. 1, fig. 2 (incorrectly cited as fig. 3).

Alycaeus balingensis - Foon and Liew 2017: 21-23, figs 7A, B, 10, 31A.

Type locality.

"Bukit Baling, Kedah, rather common".

Material examined.

Bukit Baling, Kedah, leg. Tweedie, Dec. 1938, NHMUK 1948.10.2.4 (1 syntype).

Remarks.

Protoconch matte, without spiral striation; R1 with regular, dense riblets which become sparser anteriorly; R2 extremely short, with low, blunt ribs; R3 with widely spaced, regular, strong but low ribs.

The globular shell shape suggests that this species belongs to Pincerna . However, the dense ribbing would be unusual in Pincerna , and the radular morphology is identical with that of S. perakensis .
