Taxonomy: For all marine species, Project Gastropods uses the taxonomy in the online database WoRMS. When starting a new article, do not use sources of taxonomic information that predate the 2017 revision for all gastropod groups ("Revised Classification, Nomenclator and Typification of Gastropod and Monoplacophoran Families" by Philippe Bouchet & Jean-Pierre Rocroi, Bernhard Hausdorf, Andrzej Kaim, Yasunori Kano, Alexander Nützel, Pavel Parkhaev, Michael Schrödl and Ellen E. Strong in Malacologia, 2017, 61(1–2): 1–526.) (can be dowloaded at Researchgate.net), substituting the previous classification of 2005 Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005).

Extinction claim based on taxonomic confusion

I don't have time to work out how to best fix this right at this moment but this page has incorrectly treated the widespread species Lamellidea novoseelandica as extinct simply because a name of a species that was considered to be extinct by IUCN became a synonym of it. All specimens of Tornelasmias capricorni are now classified under Lamellidea novoseelandica but not the other way round; the parent species does not automatically take on the threat status of the synonymised name. This seems to be a common issue here when threatened-listed names become synonymised. Therealsleepycat (talk) 02:09, 28 December 2024 (UTC)[reply]

If you can find a reference that this species is not extinct, we can update the article accordingly. Without that, we can only do so much. - UtherSRG (talk) 14:49, 28 December 2024 (UTC)[reply]

https://ssbbulletin.org/index.php/bssb/article/view/8873 refers to the synonymy of the species and includes numerous recent records in a table. Therealsleepycat (talk) 21:49, 28 December 2024 (UTC)[reply]

Great! That's step one. Can you point out where in the article it says it is extant or, better, that it gives a conservation status? - UtherSRG (talk) 00:39, 29 December 2024 (UTC)[reply]

The article text is the PDF link https://ssbbulletin.org/index.php/bssb/article/view/8873/7924 It refers to L. novoseelandica by name dozens of times. The main section dealing with the species is on p. 27, eg "Ecology:

Lamellidea novoseelandica is present in a wide range of habitats in New Zealand, from the coast to altitudes of several hundred meters, in native grassland,shrub-land, and tall forest.It lives on the ground in leaf litter [..]"

L. novoseelandica doesn't have an IUCN conservation status; it is too common and widespread for anyone to have bothered assessing it.

The problem here has been with the transferring of the original page for Tornelasmias capricorni to the new senior name when they're not the same thing. T. capricorni is an IUCN listed extinct "species" based on a listing from 1996 but the Goulding et al study has found that T. capricorni isn't really a species at all but rather refers only to a local (now extinct) population of L. novoseelandica.

Perfect. Now you have all the data needed to update the article yourself. - UtherSRG (talk) 14:31, 29 December 2024 (UTC)[reply]
