Eastern Pacific Nudibranch News - Revisions in Genus Coryphella

Pacific Northwest nudibranch observers: Two new name changes, but you don't have to do anything.

1) Predaceous Aeolis (Himatina trophina) has a new genus name once again. The current name is now Coryphella trophina. I have retained the old common name (Predaceous Aeolis) for clarity.

2) Coryphella pseudoverrucosa is no longer a separate species. It is now considered a junior subjective synonym of Coryphella verrucosa (Red-fingered Aeolis).

In both cases, you do not have to go back and rename your Observations, it happened automatically when I did the taxon swaps.

Eastern Pacific Nudibranch News - New Name for Janna's Dorid: Genus Knoutsodonta now Genus Atalodoris

Since iNat follows WoRMS, and this new genus has been accepted by WoRMS, Genus Knoutsodonta - Hallas & Gosliner, 2015 is now Genus Atalodoris - Iredale & O'Donoghue, 1923. Citation: https://www.marinespecies.org/aphia.php?p=taxdetails&id=597122

Good news, do nothing!
If you have old Observations of Janna's Dorid, the name has automatically been changed to Atalodoris jannae and you don't need to do anything. The same is true for all the observations of the 15 other species in the genus.

The common name remains the same.

Genus Knoutsodonta is now Inactive and should not be used for Observation IDs. Citation: https://www.marinespecies.org/aphia.php?p=taxdetails&id=845525)

For now, I have included the undescribed Knoutsodonta sp-a in the genus name change to Atalodoris, though this may need further review.

New: The Pot Fouling Project (and already a new snail!)

One day into the new project, already something interesting. A first on iNat for the SF Bay Area: Southern Flatcoil Snail. This snail was in a plant nursery in Cupertino, Santa Clara County, CA: https://www.inaturalist.org/observations/101369553


Please join The Pot Fouling Project if you are interested in land snails and slugs, mushrooms and other fungi, salamanders and newts, millipedes, centipedes, spiders, insects, terrestrial worms, etc. Anything that lives under a human-made garden container is fair game to add to this project. Urban or rural as long as it's under something, so check out nurseries, public gardens, etc. And perhaps it will help scientists track invasive species too, so yay for that.

Pots (and nurseries) remind me a little of the man-made marinas and harbors where I go dock-fouling; they might provide "safe harbor" for non-native species to establish themselves through inadvertent introduction. AKA Ground Zero.

Able to help on the snail?: Rookie question: Southern Flatcoils are widespread across the Southern US, including Southern California, but I have yet to find a record of them in the San Francisco Bay Area, which strikes me as weird. They do not appear in Roth & Sadeghian's checklist, but I can't imagine this is really the first record of them here. If you are a California land snail expert - and I'm looking very hopefully at you @jannvendetti @cedric_lee @pliffgrieff @thomaseverest @tlawson @susanhewitt @finatic @oksnaillaboratory - could you please weigh in on this if you have a chance?

E. Pacific Nudibranch News: Two New-to-Science Nudibranchs Found on the California Coast

Not one, but TWO new-to-science nudibranchs were found this summer in California. Both were spotted by iNaturalist community scientists (Luan Roberts and Siena McKim). For photos and more info: https://www.mbnep.org/2021/10/15/new-undescribed-nudibranchs-on-the-california-coast/?fbclid=IwAR3LsOHTfBPyJVs7ILscOi2WDBS1_ZgNjAip68a4F0lKIm3eoMVCu5BMZbI

Obscuring my tidepool observations in SF Bay Area counties

A sad decision. It may not help as much as other more tangible measures to stop the widespread taking/destruction of the local reefs that began in early 2020, but I don't want my personal iNat observations to assist tech-saavy foragers in any way. For now, this means Mollusks in San Francisco, Marin, San Mateo, Santa Cruz and Monterey counties only and genus Cancer crabs statewide.

Yes, it will now look like some tidepool creatures were seen miles inland. Sorry about that... If this affects your conservation project, and you need the precise locations of my observations, please message me privately, I'm happy to help.

Eastern Pacific Nudibranch News: Tritoniidae: 1) reinstated Tritonia exulsans and 2) New genus Tritonicula (affects 5 species)

Two recent taxon splits from a new paper from Tatiana Korshunova and Alexander Martynov (citation below). Action is only required on the first change.

Change #1: Tritonia exsulans has been reinstated - most recently it was included in Tritonia tetraquerta - and all iNat Observations WILL need to be re-reviewed since the ranges overlap. The super short, nonscientific answer on the visual difference/range is:

T. exsulans: Pink or salmon color, with white lines on the oral veil and between the dorsolateral appendages (range is California to British Columbia)
T. tetraquerta: Orange color, no white lines (range is Oregon to Kamchatka and Kuril Islands)

Change #2: Tritonicula: A new genus name for five species of Family Tritoniidae (Lamarck, 1809). I made the change to the new names in iNat this morning, and no manual changes are required (yay!). The new species names are:

Tritonicula bayeri (Ev. Marcus & Er. Marcus, 1967)
Tritonicula hamnerorum (Gosliner & Ghiselin, 1987)
Tritonicula myrakeenae (Bertsch & Osuna, 1986)
Tritonicula pickensi (Ev. Marcus & Er. Marcus, 1967)
Tritonicula wellsi (Er. Marcus, 1961)

Here's the full paper: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0242103
