Astarte (Digitariopsis) grueti n. sp.et Astarte (Digitariopsis) excurrens lardeuxi n. subsp., bivalves endemiques du Redonien (Pliocene de l'Ouest de la France)

Two new bivalvia (Astartidae) are described. Astarte (Digitariopsis) grueti n. sp. is present in both the Earlyand Late Redonian localities; it confirms the hypothesis of a unique Redonian transgression. Astarte (Digitariopsis) excurrens lardeuxi n. subsp. is a form restricted to the inner part of the Ligerian gulf, where the endemism is more pronounced.
