Ho, 1994 (p.1295, Rem.); Ho, Dojiri, Hendler & Deets, 2003 (p.592, Rem.: creation of the new order: Thaumatopsylloida); Boxshall & Halsey, 2004 (p.16; 689: Def., p.691: Genera Key. These authors do not admit the new order Cf. p.41: Rem); Ferrari & von Vaupel Klein, 2019 (p.179: the family belongs to Ordre Thaumatopsylloida and the new Superorder; Rhabdomoplea. Rhabdomoplea appears to be the earliest branch of copepods because only rthoracic somites 1-4 are broad thoughout copepodid developement and thoracic somite 5 and 6 remain narrow, diggerent from Podoplea and Gymnoplea with thoracic somite 5 transformed from the anterior narrow somite to the posterior broad somite during the moult to copepodid II. Rhadomoplea differs from podoplea in their body architecture.

Famille Thaumatopsyllidae - Planche 1issued from : J.-s. Ho, M. Dojiri, G. Hendler & G.B. Deets in J. Crustacean Biol., 2003, 23 (3). [p.591, Fig.5].
The four, very similar, equally parsimonius phylograms, all showing the Thaumatopsyllidae as sister taxon to the Siphonostomatoida and Monstrilloida.
Nota: The phylograms supports Sars' original hypothesis that Thaumatopsyllidae is allied with the Monstrilloida, and also indicate that Sewell (1949) and Fosshagen (1970) were correct to suggest its affinity to the Siphonostomatoida. The trees, however, refute Huys's and Boxshall's (1991) and Boxshall & Halsey (2004) transfer of the family to the Order Cyclopoida. An examination of the 54 characters reveals that thaumatopsyllids differ from Cyclopoida, and justifie the creation of a new order: Thaumatopsylloida.
