Checked: verified by a taxonomic editorTaxonomy Ho and Perkins (1977: 368) proposed the genus Namakosiramia Ho & Perkins, 1977 for a new species N. californiensis Ho & Perkins, 1977 (type by original designation) and established the family Namakosiramiidae in the order Siphonostomatoida to accommodate it. Huys (1988a: 1520, 1522) placed the family in the order Harpacticoida and relegated it to a junior subjective synonym of the family Laophontidae T. Scott, 1905a. Kim (1991: 429) added a second species, N. koreensis Kim, 1991, to the genus.
Brady (1918: 34), in a brief supplementary note to his report on the Copepoda collected during the Australasian Antarctic Expedition 1911–1914, proposed the genus Microchelonia for a single species, M. glacialis Brady, 1918 (type by monotypy). The genus was not mentioned in Lang’s (1948) monograph and does not feature in the Nomenclator Zoologicus (Neave 2005). It was listed as a genus inquirendum by Boxshall and Halsey (2004: 844) but without ordinal or familial assignment. Although Brady (1918: 34) stated that M. glacialis may “...form the type of an entirely new division of the Copepoda...”, the illustration of the first leg (labelled as the “anterior antenna”; Plate 15, Fig. 4) indicates that Microchelonia is a member of the harpacticoid family Laophontidae. The general dorso-ventrally depressed habitus, the shape of the P1 endopod (and claw), the powerful P2 (shown in the habitus drawings; Plate 15, Figs 1–2), the reduced P2–P3 (labelled as “posterior antenna”; Plate 15, Fig. 5) and P5 (labelled as “maxilliped”; Plate 15, Fig. 6), and the short caudal rami bearing one long principal seta unequivocally identify M. glacialis as a member of the genus Namakosiramia which should consequently sink as a junior objective synonym of Microchelonia Brady, 1918. The genus contains three species: M. glacialis, M. californiensis (Ho & Perkins, 1977) comb. nov. and M. koreensis (Kim, 1991) comb. nov.
