 Comments
       
  Comment: Arachnida was previously changed from a class to a subclass in ITIS in order to accomodate class Euchelicerata (Arachnida + Xiphosura), per publications such as G. Giribet & G. Hormiga in Brusca et al. (2016), and G. Giribet (2018). Although Euchelicerata is a useful taxonomic group, arachnologists typically treat Arachnida as a full class, rather than a subclass. To accomodate this preference, ITIS is reverting to using Arachnida and Merostomata as full classes, instead of subclasses of class Euchelicerata
