**Pinufiidae** is a [family](/source/Family_(taxonomy)) of [sea slugs](/source/Sea_slug), specifically [nudibranchs](/source/Nudibranch), [marine](/source/Marine_(ocean)) [gastropod](/source/Gastropod) [molluscs](/source/Mollusc) in the superfamily [Fionoidea](/source/Fionoidea).[1]

In Korshunova et al. (2025), Pinufiidae was not recognized as a family but as a subgroup or 'subfamily' of the family [Trinchesiidae](/source/Trinchesiidae). This is due to the type genus *[Pinufius](/source/Pinufius)* bearing close relations the trinchesiid *[Phestilla](/source/Phestilla)*[2].
