Oleellisina

I’m not finding a verifiable source for a term or taxon named “oleellisina.” If you meant a real genus or species, please share a source or context. If you’d like, I can create a neutral, wiki-style stub as a fictional or hypothetical entry for “Oleellisina,” perhaps as a genus in the olive family (Oleaceae), or I can write about a real related group such as the genus Olea. Which would you prefer?
