Merge discussion

[edit]
The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.
To not merge, as the genus is not monotypic, including at least Trypaea australiensis and Trypaea mizunamensis; improvement warranted. Klbrain (talk) 07:58, 25 February 2024 (UTC)[reply]

Pinging @Jlwoodwa, who forgot to start this discussion. Edward-Woodrow :) [talk] 12:36, 3 September 2023 (UTC)[reply]

Merge rationale: WP:MONOTYPICFAUNA. The species article was created by Qbugbot, seemingly in error since the edit summary of

qBugbot replaced self-redirect with article. 03:10, 26 January 2020

was incorrect (it was not a self-redirect). jlwoodwa (talk) 16:32, 3 September 2023 (UTC)[reply]
  • Oppose. Trypaea Dana, 1852 sensu Sakai, 2010 is not monotypic. Although NCBI only showcases Trypaea australiensis, this is because it is the only sequenced species. Other Trypaea species that I have found with a quick search are:[1]

WoRMS describes the genus as monotypic, and each species you listed as unaccepted > superseded combination in favor of placement in another genus. jlwoodwa (talk) 16:54, 3 September 2023 (UTC)[reply]
@Jlwoodwa Oh wow... I just took a look at the WoRMS page and it is quite a hot mess. Some of the unaccepted taxa aren't explained, while others have a more recent paper to back them up. This is more controversial than I initially thought, I revert my opposition until further research on my part. I don't trust WoRMS as the reliable authority, so I think the best thing to do here is to research every species one by one and see which ones are accepted in recent literature and which ones aren't. —Snoteleks (Talk) 17:05, 3 September 2023 (UTC)[reply]
@Snoteleks and Jlwoodwa: Here's what my rounds of the taxonomic databases shows:
  • CoL: Not listed.
  • GBIF: Three species.
  • WoRMS: quite a hot mess indeed.
  • OBIS: one accepted species.
Like Snoteleks, I'll withdraw my opposition until we find out what's going on.

Atlas of Living Australia follows OBIS & WoRMS, EOL sort of follows GBIF. Edward-Woodrow :) [talk] 17:11, 3 September 2023 (UTC)[reply]
Support. After a surprisingly quick research, I found the newest taxonomic revision of the entire Callianassidae (as of 2019)[2] and it says:
So it seems that this Sakai individual made a lot of sudden taxonomic changes back and forth during the early 2000's. Right now, the revision only accepts Trypaea australiensis as the only species, while the rest of the species are comb. nov.'d as different genera:
I expect the rest of the species have been displaced to other genera in previous years, judging by how they are not mentioned here. Anyways, mystery solved I think? —Snoteleks (Talk) 17:19, 3 September 2023 (UTC) —Snoteleks (Talk) 17:19, 3 September 2023 (UTC)[reply]
Right -- According to WoRMS, these are members of other genera now. The two extinct species are the only accepted ones I could find. Bob Webster (talk) 17:27, 3 September 2023 (UTC)[reply]
Oppose. Nevermind. The two extinct species Trypaea inornata and Trypaea mizunamensis make it not monotypic. I revert my support. —Snoteleks (Talk) 17:32, 3 September 2023 (UTC)[reply]
On another note, I seem to find no literature record of Trypaea inornata, while Trypaea mizunamensis is very much present.[3][4] —Snoteleks (Talk) 17:38, 3 September 2023 (UTC)[reply]
  • Oppose: Trypaea duplicates Trypaea australiensis, yes, but the genus isn't monotypic here. The problem is that the Trypaea article needs a rewrite.

Edward-Woodrow :) [talk] 12:36, 3 September 2023 (UTC)[reply]

The article currently states:

the only species in the genus Trypaea

Was another species added recently? jlwoodwa (talk) 16:21, 3 September 2023 (UTC)[reply]
  • Oppose: According to WoRMS, there are two extinct species in this genus, in addition to australiensis, the only accepted extant species. I've added these to Trypaea. If the articles are not merged, it would be good idea to make sure all the species specific information in the genus article appears in the species article, and to make the first sentence of Trypaea about the genus instead of the species. (The species article was created by Qbugbot because there was a self-direct link in the genus article. It was in the caption of a photo, so not a big deal.) — Preceding unsigned comment added by Edibobb (talk • contribs)
