Ekimova et al. (2026) states that more data is needed to confirm its placement in Coryphella. Korshunova et al. (2025), however, cautiously proposes that Coryphella californica is in fact a junior synonym of Flabellinopsis iodinea; the description of the preserved and therefore somewhat distorted specimen of C. californica does not contradict the original description of F. iodinea in any meaningful way, and shares with it some similarities, while not sharing any similarities with CoryphellidsKorshunova T.; Fletcher K.; Martynov A. (2025). The endless forms are the most differentiated—how taxonomic pseudo-optimization masked natural diversity and evolution: the nudibranch case Zoological Journal of the Linnean Society.

Distribution This species was described from California. It does not seem to have been recognised since the original description.
