An Early Jurassic foraminiferal species, reported previously under the name of Eoguttulina sp. 1, from the uppermost Pliensbachian sediments of western Central Portugal, is formally described and its stratigraphical distribution in SW Europe more precisely defined. The short stratigraphic range (uppermost Pliensbachian, spinatum Zone, hawskerense Subzone to lowermost Toarcian, tenuicostalum Zone, mirabile Subzone) and the distinctive morphology of Eoguttulina palomerensis sp. nov. (Lagenina, Polymorphinidae) make it an extremely useful biostratigraphic marker for this boundary interval.
