Pseudosimnia wieseorum
species of mollusc
Pseudosimnia wieseorum is a species of sea snail, a marine gastropod mollusk in the family Ovulidae, the ovulids, cowry allies or false cowries.
Description
Original description: "Shell light and fragile, some have a slightly callous base. The shape is pyriform and varies little, with tapered extremes and a slightly margined dorsum. The dorsum is finely striated transversally, especially towards the extremities. The internal part of the labrum has 17 to 25 sharp denticles. The terminal plica on the columellar side shows slight traces of 2-4 denticles, while the rest of the columella is smooth. The fossula is well pronounced in adult specimens and forms a jutting callous line along the sulcus. The aperture bends sharply to the left. The base is white but may become pale yellow towards the margins which are bright yellow, especially the external one. The dorsum is white, with two indistinct pale purple zones towards the extremities and is distinctly framed by a bright orange band on the labial side.
Begin with the source’s own compact description: “Pseudosimnia wieseorum” is species of mollusc. The dossier treats that line as a proposition to test through Pseudosimnia, wieseorum and species, not as a finished interpretation.
Why this record matters
The phrase “species of mollusc” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q7255566. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
