The article Cryoturris albida has been proposed for deletion because of the following concern:

Both Polystira albida and Cryoturris albida are synonym to Pleurotoma albida, they are equal. The former should be kept. (World Register of Marine Species & bagniliggia.it)

You may prevent the proposed deletion by removing the {{proposed deletion/dated}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing {{proposed deletion/dated}} will stop the proposed deletion process, but other deletion processes exist. In particular, articles for deletion allows discussion to reach consensus for deletion based on established criteria.

If the proposed deletion has already been carried out, you may request undeletion of the article at any time. Labratscientist (talk) 09:33, 10 March 2026 (UTC)

No, they are not all synonyms but rather homonyms. Pleurotoma was used in the 1800s as a massive "catch-all" category for hundreds of different sea snails. George Perry described in 1811 Pleurotoma albida in the family Turridae. This later became a a direct synonym of Polystira albida.

In 1845, Charles Baker Adams described a completely different, much smaller snail also belonging to the family Turridae and also named his new shell Pleurotoma albida. This has now become an invalid junior homonym of Cryoturris albida, but WoRMS still regards it as an unsettled issue and gives it the status "uncertain - unassessed". This is adding to the confusion.

Cryoturris albida is therefore, in my opinion, a distinctly separate, valid species. It is not a synonym of Polystira albida. JoJan (talk) 12:28, 10 March 2026 (UTC)

I see. My original reasoning was definitely wrong, but I still think it should be removed. Based on my understanding now, the three most accepted database for gastropods should be WoRMS, WMSDB and GBIF. And WoRMS is generally regarded as more reliable. However, someone else should be making these decisions. I am surprised there's not a detailed WP:NSPECIES I can refer to.

@Labratscientist: Whenever I felt something was inconsistent or strange in the descriptions on WoRMS, I contacted WoRMS by email, as I have done numerous times. Only after having received their answer, I make a final judgment. JoJan (talk) 14:31, 20 March 2026 (UTC)

Sure, sounds good. Labratscientist (talk) 15:20, 20 March 2026 (UTC)

Article Caliphyllidae should be probably recovered. I have no idea why it "disappeared" 3 years ago. Its category Category:Caliphyllidae too. Snek01 (talk) 16:12, 19 April 2026 (UTC)

It was changed to a redirect with this edit in 2023. You can just undo it to restore the old article. It and Hermaeidae would need updating. I assume this is due to changes on WoRMS, establishing and reversing the synonymy.  —  Jts1882 | talk  10:05, 26 April 2026 (UTC)

I would like to bring to this Wikiproject's attention the large amount of small articles about Gastropods. I've seen a lot of stubs here about this topic. Walteronthehill (talk) 15:34, 24 April 2026 (UTC)

I have recently been working on a draft for Parakaliella serica, a species of land snail endemic to the Korean Peninsula. I have included its taxonomic information, morphological description, and habitat details based on resources like the National Institute of Biological Resources (NIBR), as well as a few images of the shell.

As I am still quite new to editing Wikipedia, I would greatly appreciate it if members of the Gastropods WikiProject could take a look. Any feedback on the formatting, biological accuracy, or suggestions on what else might be needed before it gets fully published into the mainspace would be incredibly helpful.

I made a few changes to the taxobox, taxonbar and citations, with edit summaries explaining each. The biggest problem is the taxonomy. The MolluscaBase/WoRMS classification that is usually followed places Parakaliella in Chronidae rather than Helicarionidae. The automated taxobox system provided the MolluscaBase classification for Parakaliella. I'm assuming Helicarionidae is an older classification, but haven't changed the text, as that probably needs discussion.  —  Jts1882 | talk  09:55, 26 April 2026 (UTC)

I agree. Chronidae is the correct updated classification, and Helicarionidae is outdated.

I will go ahead and update the text to reflect the Chronidae classification. II52tt52 (talk) 14:13, 26 April 2026 (UTC)

I've just been going through the Achatinella species articles adding IUCN/NatureServe/CITES statuses to speciesboxes, and in doing so noticed that a few of these articles are located at names which have been reduced to synonymy or subspecific status by MolluscaBase.

• Achatinella elegans is now accepted as Achatinella bulimoides elegans by MolluscaBase/WoRMS (last updated 2021) and by NatureServe (last updated 2003) - the IUCN Red List still uses A. elegans, but that assessment has not been updated since 1996.
• Achatinella cestus is now accepted as Achatinella apexfulva cestus by MolluscaBase/WoRMS (last updated 2021) and by NatureServe (last updated 2022) - as with the above taxon, the IUCN red List still uses A. cestus but has not been updated since 1996.
• Achatinella leucorraphe is now accepted as Achatinella apexfulva leucorraphe by MolluscaBase/WoRMS (last updated 2023) and by NatureServe (last updated 2022) - as with the above taxa, the IUCN Red List still uses A. leucorraphe but has not been updated since 1996.
• Achatinella swiftii is now accepted as a junior subjective synonym of Achatinella turgida by MolluscaBase/WoRMS (last updated 2023). NatureServe lists A. swiftii separately from A. turgida but the assessment states Synonym of Achatinella turgida Newcomb, 1854 (Cowie et al., 1995: 47). Treated here as a nonstandard following the U.S. Fish and Wildlife Service listing (USFWS 1981). The IUCN Red List uses A. swiftii, but has not been updated since 1996.

I'm not sure what the best option for each of these articles is, whether they should be merged or simply moved to the name currently accepted by MolluscaBase, but I am happy to leave that up to other editors - I just wanted to flag that these articles need updating in hopes that an interested editor will give them some attention.

I've made the redirects and add some more data to the articles. JoJan (talk) 08:46, 28 April 2026 (UTC)
