E. Pacific Nudibranch News: Six Deepwater Nudibranchs added to iNat (and CA Nudibranchs Guide)

Happy Holidays! Based on WoRMS (referencing Angel's 2018 paper https://biotaxa.org/Zootaxa/article/view/zootaxa.4526.4.1), I have added six new deepwater nudibranchs to iNat, four of which also were added to the CA Sea Slugs Guide. We can only hope that one will wash ashore someday - or perhaps an MBARI researcher will share a few photos!

They are:

- Aeolidia libitinaria (Undertaker Nudibranch, found under whale bones)
- Ziminella vrijenhoeki (Vrijenhoeki's Nudibranch - also under whale bones)
- Tritonia nigritigris (Black Tiger Nudibranch)
- Zeusia herculea (fanciful but no common name yet - I'm guessing this is a big one?)
- Cuthona methana (Named re methane seeps, but no common name yet) - OREGON
- Dendronotus claguei (Clague's Nudibranch) - MEXICO, south of the Gulf of CA

Here's a quick read about them from MBARI, with photos and a cool video.

@kueda will perhaps note some wordier similarities in the opening paragraph of the article with his own intro to the CA Sea Slugs Guide... ;-)

PS. We now have 180 sea slugs in the CA Guide!

Pulmonata and Opisthobranchia... and WoRMS

Hi Mollusk Curators/Taxonomy Experts,

We've been called upon to make a group decision! :-O

As curators, our standing orders for iNaturalist mollusk curation are to "follow WoRMS." So today in the interests of keeping iNat tidy, I took a look -- and I noticed that WoRMS has changed the taxonomy for Opisthobranchia and Pulmonata, which are no longer accepted concepts.

So OK, that means it is time to update iNat to align it with WoRMS, right? Or maybe not? Ken-ichi has asked me to ask you what WE want to do, since this is above Order level (and thus off limits to humble curators), and would require some iNat resources to sort out all the observations. How much resources? Well, as of this minute we have 38,000 Opisthobranchia observations (of which 33,000 are Nudibranchs). That's somewhere between Buteos (hawks) at ~34,000 and Larinae (gulls) at ~43,000. So not huge by other Life standards, but according to Ken-ichi, still some processing time as well as the human time would be involved.

The task: We'd have to start with subclass Heterobranchia - still accepted, and 88,000 observations on iNat - and work down, aligning everything with WoRMS. But even the first step seems to get messy, at least to my uneducated eye; take a look at WoRMS and there's terms like 'unassigned' and 'Lower Heterobranchia' -- ?? http://www.marinespecies.org/aphia.php?p=taxdetails&id=14712 And so it goes, on down to our more familiar Nudibranchia-level territory.

Now, not being a trained biologist myself, I'm opinionless - but willing to compile your replies into a document that iNat can either 1) act upon as per WoRMS; or 2) do a few tweaks; or 3) do nothing, and at least have an expert opinion/reason or two for doing so until something else changes in the future.

And of course, at least we'll all know what's going on.

So -- please reply! And thank you for your time!

In no particular order, and feel please free to forward to other curators/experts: @kueda @mcduck @tgosliner @jeffgoddard @bernardpicton @jpsilva @v_s_ @lemurdillo @allisonjgong @rebeccafay @kestrel @susanhewitt @pliffgrieff @sluglust @maractwin @erwinkoehler @johnturnbull

New Guide: Opisthobranchs of Baja California Peninsula

Hi Everyone,
Today is Day One of the publication of this guide, so it is likely to be sketchy and full of errors. That's where you come in @jeffgoddard @mcduck @kueda @bahia_de_loreto @claudia_jeannette @nezahualpilli @kestrel @tgosliner and anyone else with an interest! Please message me any additions/removals/unspeakable horrors you notice, and I will gladly fix it.

Cheers,
- Robin

Limacia mcdonaldi now active on iNat

Limacia split now complete on iNat, yay. Limacia mcdonaldi was finally accepted on WoRMS, so congratulations to all involved, especially Gary.

Homework time for a rainy day: If you feel motivated, please go through your old Limacia observations and re-identify each one. Simplistically:
L. cockerelli - bald spot
L. mcdonaldi - snazzy racing stripe of orange dots

;-)

QUESTION re nudibranch family-level updates: Superfamily Fionidae and above

More changes, and a question down at the bottom! @kueda

As per an email from @bernardpicton today, I've spent the morning (hopefully updating iNat correctly) to reflect the latest updates on WoRMS, which are based on this paper he co-authored:

Korshunova, T.; Martynov, A.; Picton, B. (2017). Ontogeny as an important part of integrative taxonomy in tergipedid aeolidaceans (Gastropoda: Nudibranchia) with a description of a new genus and species from the Barents Sea. Zootaxa. 4324(1): 1., available online at https://doi.org/10.11646/zootaxa.4324.1.1

Among other things, this update "unmerges" @jpsilva 's Taxonomic Merge 18846, which he only recently committed on 2016-12-27. In other words, this reinstates the following families under superfamily Fionoidea:
- Tergipedidae
- Eubrachidae
- Calmidae
- Fionidae
And there are other changes as well, which hopefully I've reproduced correctly on iNat. Please tell me if I haven't!

HOWEVER!, my question for you experts is this (and please bear in mind that I am not a taxonomist, merely a volunteer!): On iNat, there is a hodge-podge of families, superfamilies and one infraorder under the Order Nudibranchia. However, on WoRMS, the structure has suborder, infraorder, and parvorder before getting down to Superfamily Fionoidea:
(http://www.marinespecies.org/aphia.php?p=taxdetails&id=412646). Unfortunately iNat doesn't seen to have parvorder, so I'm stumped as to how I should connect, since we follow WoRMS, without botching things terribly. I'm willing to spend the time to update and reorganize things, but uncertain how to proceed in this case.

Thanks @bernardpicton @kueda @jpsilva (and anyone else willing to chip in!) for whatever you can suggest!

Nudibranch name updates: Abronica abronia and Tenellia albocrusta

Just updated on iNat:
1 - Cuthona abronia now Abronica abronia
2 - Cuthona albocrusta now Tenellia albocrusta

Both should update automatically on everyone's observations with no further action required.

Both changed as per this article: Cella, Kristen, Leila Carmona, Irina Ekimova, Anton Chichvarkhin, Dimitry Schepetov, & Terrence M. Gosliner. 2016. A radical solution: the phylogeny of the nudibranch family Fionidae. PLoS ONE 11(12):e0167800
