Trinchesia

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.

Trinchesia species feed on hydroids.
