Coryphellidae is a family of nudibranchs, shell-less marine gastropod molluscs or sea slugs, in the superfamily Flabellinoidea.[1]
Taxonomic Developments
[edit]Modern developments in molecular analysis technology has provided another very useful tool to refine classification, yet its introduction has incited chaos across taxonomies of all ranks and areas of studies. Over-reliance on molecular analysis alone can undo potentially centuries of taxonomical progress, as morphological traits are ignored in favour of subjective COI distances and percentages, resulting in "lumping" taxa together and a complete loss of distinction and defeating the purpose of any classification at all[1]. However, over-reliance on morphological analysis alone can result in designations so incredibly narrowed by "splitting", that it loses all practicality and obscures the relationships it set out to define[2].
Coryphellidae is one taxon of many that remains at the center of conflict in sea slug academia between these extreme taxonomical philosophies. In the most recent development, the Ekimova et al. (2026) study resulted in conclusions that reversed select results of Korshunova et al. (2025) regarding "Flabellinidae sensu latissimo"[2], the phrase used therein to encompass the species of concern without acknowledging Korshunova et al.'s reinstatement of several superfamilies the year prior[1].
Ekimova et al. synonymized Coryphellidae with Flabellinidae, and synonymized all genera previously in Coryphellidae with Coryphella[2]. It is very important to note that while this resulted in invalidating Orienthella as an accepted genus, Orienthella piunca currently remains a fully accepted species, as it was the only member of Orienthella not included in the Ekimova et al. (2026) study.
