Records of extreme altitudes where several coccinellid species from South America inhabit the Andes of Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru are provided. After an intensive review of several entomological collections and literature, records for 35 species with at least one location over 3500-m elevation were obtained, including the genera Cycloneda (ten species), Eriopis (15 species and one subspecies), Harmonia (one species), Hippodamia (two species), Mimoscymnus (two species), Psyllobora (one species), and Stenadalia (four species). In total, 184 location records are listed, of which 119 were frombetween 3000 and 4000m, 57 between 4000 and 4900 m and eight above 4900 m, with the highest altitude record at 5250 m for Eriopis minima Hofmann. All records above 4000 m were obtained in the Puna biogeographic province within the Paramo Puneña biogeographic subregion. These records are the highest altitudes observed for the American continent and by far surpass others known for coccinellids worldwide. Several species of coccinellids living in sympatry at these high altitudes were verified, and in some cases, in situ development was inferred by the presence of immature stages. These findings are important to foresee the future effects of global warming that will affect especially the biological communities of extreme altitudes.
