dc.description.abstractTHE SPECIES OF THE GENUS POTAMOLITHUS INHABITING THE SOUTHWESTERN BASIN OF THE ANDES ARE DIFFICULT TO DISTINGUISH DUE TO SMALL SIZE AND SIMILAR SHELL MORPHOLOGY. ONLY POTAMOLITHUS AUSTRALIS AND POTAMOLITHUS SANTIAGENSIS HAVE BEEN TRADITIONALLY RECOGNIZED IN THIS REGION, BUT THE OCCURRENCE OF SEVERAL MORPHOLOGICALLY SIMILAR UNDESCRIBED POPULATIONS COULD INCREASE THE REGIONAL RICHNESS. HERE WE DELIMIT DESCRIBED AND POTENTIALLY UNDESCRIBED CRYPTIC SPECIES OF THE GENUS USING PARTIAL SEQUENCES OF THE MITOCHONDRIAL CYTOCHROME C OXIDASE SUBUNIT I (COI) GENE. NETWORK ANALYSIS AND DIVERSITY INDICES INFERRED SIX HIGHLY DIFFERENTIATED HAPLOGROUPS, MANY OF THEM SYMPATRIC AND WIDESPREAD IN THE STUDY AREA. PHYLOGEOGRAPHIC ANALYSES SUGGEST A SCENARIO OF RECENT DIVERSIFICATION AND THE OCCURRENCE OF MULTIPLE REFUGES DURING THE SUCCESSIVE PLEISTOCENE GLACIATIONS. PHYLOGENETIC ANALYSIS ALSO RECOVERED SIX MAJOR CLADES THAT SHOWED NO RELATIONSHIP WITH PHYSIOGRAPHY. SPECIES DELIMITATION ANALYSES CONSISTENTLY RECOGNIZED THREE OR FOUR CANDIDATE SPECIES APART FROM P. AUSTRALIS AND P. SANTIAGENSIS. DIVERGENCE TIMES INDICATE THAT SPECIATION OF CHILEAN POTAMOLITHUS BEGAN AT THE END OF THE PLIOCENE, PROBABLY DRIVEN BY CLIMATIC RATHER THAN GEOGRAPHIC EVENTS. CONSIDERING THE HIGH INTER- AND INTRA-BASIN GENETIC DIVERSITY, CONSERVATION EFFORTS SHOULD BE FOCUSED ON PROTECTING SYMPATRIC TAXA IN THE BASINS WITH THE HIGHEST SPECIES RICHNESS.
