Résumé
The fossil shrimp species Caridina nitida A. Milne-Edwards, 1879 described from the Oligocene la- custrine deposits of Aix-en-Provence was considered to be a nomen dubium. Based on newly discovered specimens at the type locality, we provide an illustrated re-description of this species. The detailed morphological study leads us to place C. nitida within the extant genus Dugastella Bouvier, 1912. These new data support the hypothesis of a fresh to slightly brackish palaeoenvironment. A specimen possibly corresponding to A. Milne-Edward’s holotype was found in the collections of the Muséum national d’Histoire naturelle but since the fossil shrimp is not visible anymore (destroyed), a neotype is designated among the new specimens.
