Genera with number of species
Remark by Melville, R.V. & Smith, J.D.D. 1987:23: Neogastruridae Stach, 1949. Placed on the Official Index of Rejected and Invalid Family-Group Names in Zoology. Type genus: Neogastrura Stach, 1949. A junior objective synonym of Hypogastrurinae Börner, 1906, the respective type genera of these two families having the same nominal species as type species. Opinion 435.
Remark by Melville, R.V. & Smith, J.D.D. 1987:18: Hypogastrurinae Börner, 1906. Placed on the Official List of Family-Group Names in Zoology. Type genus: Hypogastrura Bourlet, 1839. Opinion 435.

Remark by Greenslade, P., Stevens, M.I., Torricelli, G. & D'Haese, C.A. 2011:227: Nonmonophyly of Hypogastruridae is consistent with the results of D'Haese (2002).
Remark by Janssens, F. 2012.11.15: To partially resolve the paraphyly of the Hypogastruridae (see Greenslade & al., 2011), we tentatively propose to restore the Poduroidea as sister-group of the Neanuroidea and as follows = ((Podura+(Biscoia+Microgastrura))+(Paraxenylla+Xenylla)). Note: this is not yet reflected in the current taxonomic hierarchy.

Remark by D'Haese, C.A. 2002:1149: Triacanthella is more closely related to Odontellidae and Onychiuridae [then to Hypogastruridae].
Triacanthella sp. from Australia
2010 © Stevens, M.
Remark by Janssens, F. 2012.11.15: According to Greenslade & al. (2011), Hypogastruridae is not monophyletic and Triacanthella is the most basic poduromorph genus and sister-group of all other Poduromorpha. Therefore, to partially resolve the paraphyly of the Hypogastruridae, we tentatively propose to place Triacanthella in a monogenic family Triacanthellidae basic to all Poduromorpha. Note: this is not yet reflected in the current taxonomic hierarchy.
Remark by Janion, C., D'Haese, C.A. & Deharveng, L. 2012:58: The genus Triacanthella is phyletically isolated among Hypogastruridae both from a morphological and a molecular point of view.

Remark by Thibaud, J.-M., Schulz, H.-J. & da Gama Assalino, M.M. 2004:128: Mesachorutes tiliophilus Loksa & Rubio, 1966 is a species dubia. The typus has disappeared and the written description does not correspond with the drawing. This taxon belongs without doubt to Mesogastrura ojcoviensis.

Genus Gomphiocephalus Carpenter, 1908

Remark by Janssens, F. 2012.11.15: According to Greenslade & al. (2011), Hypogastruridae is not monophyletic and Gomphiocephalus is the most derived "hypogastrurid" genus, and sister group of (Brachystomellidae + Neanuridae). Therefore, to partially resolve the paraphyly of the Hypogastruridae, we tentatively propose to place Gomphiocephalus in a monogenic family Gomphiocephalidae most basic in Neanuroidea. Note: this is not yet reflected in the current taxonomic hierarchy.
