Note:

Grimaldi & Engel (2005) included †“Eomeganisoptera” Rohdendorf, 1962 and †Meganisoptera Martynov, 1932 to order †Protodonata. Phylogenetic treatment on this page follows Bechly, who considered †Protodonata paraphyletic.

Large number of clades named by Bechly are not commonly used and Grimaldi & Engel (2005) used traditional Odonata for the clade Odonatoclada Bechly, 1998
