Taxonomic remark Introduced (?as an informal group) by Boudreaux, 1979 and as a phylum by Hou & Bergström, 1995 (both with spelling and authorship "Lobopodia Snodgrass 1938"), although Snodgrass never used this term, merely "lobopod annelids" to describe a hypothetical ancestor of Onychophora, etc.; subsequently by Cavalier-Smith, 1998, as "Lobopoda phyl. nov." with Onychophora and Tardigrada as subphyla. If the latter two groups are treated as phyla, as per Ruggiero et al., 2015, Lobopoda can conceptually be viewed either as a superphylum (and is referred to thus in some works), or as a restricted phylum to cover just the fossil presumed ancestors of Onychophora and Tardigrada, which is the position taken by Hou & Bergström, under the name Lobopodia (not defined therein), and presently in IRMNG but using Cavalier-Smith's spelling, since (1) Cavalier-Smith was the first to formally erect the taxon as a phylum, (2) the spelling -ia ascribed to Snodgrass does not exist in his work, and (3) the ending -a (as opposed to -ia) is that generally used at phylum level, as per Arthropoda, Mollusca, Nematoda, etc. etc. The fossil lobopodians under consideration here (class Xenusia) are included within Onychophora by some workers. Note, recent work (cited in Ortega-Hernández, 2014) refutes any close connection between Onychophora and Tardigrada. [details]
