Alycaeus sumatranus - van Benthem Jutting 1959: 77-78, fig. 5.

Type locality.

“Unter-Lankat”.

Material examined.

Unter-Lankat, coll. Schneider, ZMB/MOLL 51748 (1 syntype, labelled as holotype; photographs examined).

Remarks.

The original description does not mention the number of examined specimens. Thus, we consider the specimen labelled holotype (ZMB/MOLL, 51748) as a syntype.

Protoconch elevated, no spiral striation visible; R1 with rather irregular, low ribs and spiral striation roughly of the same strength; R2 long, with widely spaced, sharp ribs.
