Bold ranks show taxa that will be shown in taxoboxes
because rank is principal or always_display=yes.

Taxonomic references:	J. Ortega-Hernández, "Making sense of 'lower' and 'upper' stem-group Euarthropoda, with comments on the strict use of the name Arthropoda von Siebold, 1848," Biol. Rev., vol. 91, no. 1, pp. 255–273, 2016 doi:10.1111/brv.12168. Although Ortega Hernández does not use the word phylum, any scheme that divides Panarthropoda into three phyla, which follows the long-standing practice, will treat Euarthropoda as a phylum (alongside Onychophora and Tardigrada).

Parent's taxonomic references:	This is a grouping of three phyla that does not have a formal ranking in the Linnean system. Examples of usage include http://labs.bio.unc.edu/goldstein/SmithGoldstein2017.pdf - where it is informally referred to as a superphylum Smith, Martin R; Ortega-Hernández, Javier (2014).
