| Popis: | Hidden species diversity of Corrosella Boeters, 1970 (Caenogastropoda: Truncatelloidea) in the Moroccan Atlas revealsthe ancient biogeographic link between North Africa and Iberia Khadija Boulaassafer1&Mohamed Ghamizi1&Annie Machordom2&Christian Albrecht3&Diana Delicado3Received: 3 November 2020 /Accepted: 23 February 2021#Gesellschaft für Biologische Systematik 2021 Abstract Despite the high species richness of freshwater gastropods in the western Mediterranean, the evolutionary patterns of the North African taxa are poorly understood. In a recent survey of spring habitats in the Atlas Mountains of Morocco (western Maghreb), we discovered ten snail populations anatomically resembling the genus Corrosella (family Hydrobiidae), which was supposedlyendemic to the Iberian Peninsula and southern France. Through morphological and molecular investigations, we assessed thetaxonomic status of these populations and their evolutionary origins. Molecular phylogenies based on three gene fragments (COI,16S rRNA and 28S rRNA) from snails of the newly collected populations and 12 additional congeners distributed across the Iberian Peninsula and southern France clustered together the Moroccan populations within Corrosellain a well-supported cladecomprising six putative species: two previously identified as Hydrobia marocana and Pseudamnicola pallaryi and four unknown line ages here described as species new to science. According to a molecular clock analysis calibrated with an external rate, the Moroccan clade originated ca. 7.6 million years ago (Mya) (11–4.5 Mya) and its divergence from the southern Iberia lineageslikely occurred 8.4 Mya (12.5–5.5 Mya). This suggests that the biogeography of Corrosellain the western Maghreb has been shaped by old vicariance events likely associated with the Late Miocene-Pliocene geological setting of the region and theirinterplay with the isolation conditions of springs. Our findings considerably expand knowledge of the diversity and geographicrange of Corrosellaand provide new insight into faunal relationships between North Africa and Europe.
