Stomacosmethis wilhelminae (Maassen, 2006)

Alycaeus wilhelminae Maassen, 2006: 138, figs 14-18.

Type locality.

"Indonesia, Sumatra, Aceh Besar, westcoast near Pasi, 10 km S. of Lhong, on limestone slope".

Remarks.

We had no opportunity to examine the holotype, but the original description and the photographs published therein provide sufficient information regarding the generic status of this species. The protoconch of the weathered holotype is smooth and R2 is short and regularly ribbed. Maassen (2006) questioned the generic status of A. wilhelminae based on its closed umbilicus; further investigation should focus on the value of this character. However, at the moment we see no need to classify it in a genus other than Stomacosmethis .
