Trinchesia
Sign in to saveTrinchesia is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Trinchesiidae. All species were transferred to Tenellia as a result of a DNA phylogeny study in 2016. The genus was dismembered and broken into several smaller genera in 2017 with further DNA evidence and a re-interpretation of genus and family characteristics.

Trinchesia is a genus of sea slugs, aeolid nudibranchs, marine gastropod molluscs in the family Trinchesiidae. All species were transferred to Tenellia as a result of a DNA phylogeny study in 2016. The genus was dismembered and broken into several smaller genera in 2017 with further DNA evidence and a re-interpretation of genus and family characteristics.
In yet another study, Korshunova et al., 2025 conducted a mass reassessment of Aeolidacea taxa and proposed to reverse previous motions that "lumped" taxa together indiscriminately. While The World Register of Marine Species (WoRMS) has cited Korshunova et al., 2025 across other taxonomic adjustments, in regards to Trinchesiidae, who is possibly the most controversed Aeolidean family with papers being published nearly every year from opposing camps, there has yet to be adjustments.
