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

Disclaimer: ITIS taxonomy is based on the latest scientific consensus available, and is provided as a general reference source for interested parties. However, it is not a legal authority for statutory or regulatory purposes. While every effort has been made to provide the most reliable and up-to-date information available, ultimate legal requirements with respect to species are contained in provisions of treaties to which the United States is a party, wildlife statutes, regulations, and any applicable notices that have been published in the Federal Register. For further information on U.S. legal requirements with respect to protected taxa, please contact the U.S. Fish and Wildlife Service.
