The U.S. Fish and Wildlife Service Announces the Technical Corrections for the Names of 60 Species in the Pacific Islands

The Corrections Address Changes to Scientific and Common Names of Species Listed Under the Endangered Species Act

HONOLULU — The U.S. Fish and Wildlife Service (Service) has announced the technical corrections for 60 species in the Pacific Islands that are listed as endangered or threatened under the Endangered Species Act. The corrections include scientific names, as well as some common names for these species; however, these taxonomic changes do not affect their range or endangered status. The technical corrections also identify correct usage of Hawaiian and Chamorro diacritical marks in common names for certain species. This rule will be available for public comment for 30 days.

The purpose of the technical corrections is to update names based on new information and to ensure uniformity and clarity in the way the information is presented to the public. For some species, both scientific name and common names were corrected to reflect new data or their place of evolutionary origin, while for other species only the scientific or common names were corrected. We describe a few examples of these changes below:

The ʻōpeʻapeʻa (Hawaiian hoary bat) was thought to be more closely related to hoary bats commonly found on the continental U.S. and was listed as an endangered subspecies with the scientific name Lasiurus cinereus semotus. More recent analysis concluded ʻōpeʻapeʻa are full species, reclassifying them as Aeorestes semotus.

The nosaʼ Luta or Rota bridled white-eye (Zosterops rotensis) is a small bird endemic to Rota in the Commonwealth of the Northern Mariana Islands. While its scientific name continues to be accepted, its common name will be changed to Rota white-eye because new data shows it is a separate species and not a subspecies of the bridled white-eye (Zosterops conspicillatus) as previously thought.

Many species in the Pacific Islands are also recognized by their Hawaiian or Chamorro language, and their names are regularly referenced in Service documents. To improve public communication, understanding, and engagement with local conservation partners, these names have been added as accepted names for these species. However, due to the codification process some publications, such as the Code of Federal Regulations, will not display diacritical’s as they are not accurately able to represent the consistency of an ʻokina.

This proposed rule will be available for public comment for 30 days.
