Taxonomy

Robson originally placed Adelieledone polymorpha in the genus Graneledone . [4] It was then placed in the genus Pareledone , but was moved to the genus Adelieledone in 2003. [5] Robson also split Adelieledone polymorpha into two varieties, oblonga and affinis; that distinction was removed in 2003 as it was likely a result of deformation and misclassification of specimens. [6]
