Endangered Species Status for Sonoyta Mud Turtle; Final rule.

We, the U.S. Fish and Wildlife Service (Service), list the Sonoyta mud turtle (Kinosternon sonoriense longifemorale), a turtle from Arizona in the United States and Sonora in Mexico, as an endangered species under the Endangered Species Act of 1973 (Act), as amended. This rule adds the Sonoyta mud turtle to the Federal List of Endangered and Threatened Wildlife and extends the Act's protections to this subspecies.
