From editor or global species database
Synonymy Nuttall (1990) considered several Oligocene species (including Mytilopsis trigalensis Olsson, 1931) junior synonyms of the Pebasian (middle-late Miocene) Mytilopsis scripta (Conrad, 1874). Considering the vast age difference, the synonymy should be re-assessed. [details]Type locality Trigal valley of Que. Boca Pan, Peru [details]
