This tiny nudibranch was found at night at Mato Point. Although ours was a bit more red, it appears to be the species figured in Gosliner et al (2018) as Okenia sp. 4. Molecular analysis by Paz-Sedano et al (2023) recently split Okenia into several other genera, and it is likely this species belongs in one of those.
