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
