Note "Additional information: Following Lang (1948: 975), Willey (1934) and Coker (1934) thought that Canthocamptus hyperboreus was a synonym of C. illinoisensis. But Willey (1934) actually thought that C. hyperboreus is a subspecies of C. illinoisensis. The synonymy of C. hyperboreus and C. illinoisensis was adopted by Lang (1948: 978) and Borutzky (1952), but subsequent authors (e.g., Wells, 2007) kept these two as separate subspecies." for taxon Canthocamptus illinoisensis hyperborea Willey, 1925 has been added by Samuel Enrique Gómez-Noguera via the webinterface on 2024-04-25T15:41:51+00:00
