Endangered and Threatened Wildlife and Plants; Final Rule To Remove the Idaho Springsnail (Pyrgulopsis(=Fontelicella) idahoensis) From the List of Endangered and Threatened Wildlife

We, the U.S. Fish and Wildlife Service (USFWS, Service, or we), under the Endangered Species Act of 1973, as amended (Act), hereby remove the Idaho springsnail (Pyrgulopsis(=Fontelicella) idahoensis) from the Federal List of Endangered and Threatened Wildlife (List). This determination is based on a thorough review of all available data, which indicate that the Idaho springsnail is not a discrete taxonomic entity and does not meet the definition of a species under the Act. It is now considered to be part of a more widely distributed taxon, the Jackson Lake springsnail. Because the Idaho springsnail is not recognized as a species, as defined by the Act, we have determined that it is not a listable entity and are removing it from the List.
