Two new sibling species are described, Bostryx multiconspectus spec. nov and B. primigenius spec. nov., one of which is carinate. From the carinate taxa known in the Orthalicidae, 16 are occurring at localities in the Andes from northern Peru to northwestern Argentina. They belong to three genera, Bostryx, Neopetraeus and Scutalus. It is hypothesized that carination originated independently in these lineages.
