How many Siphonaria species (Gastropoda: Euthyneura) live in southern South America?
This contribution provides the first integrative revision of the Siphonaria species described and reported from southern South America, by combining information on shell morphology, distal portion of the genital system, radula, molecular data and living animal. More than 200 lots, from all along the...
