Endangered and threatened wildlife and plants, 12-month finding on a petition to list six sand dune beetles as endangered or threatened: Notice of 12-month petition finding, published July 18, 2012, finding made July 18, 2012 Text The U.S. Fish and Wildlife Service announces a 12-month finding on a petition to list six Nevada sand dune beetle species as endangered or threatened under the Endangered Species Act. After review of the best available scientific and commercial information, the USFWS finds that listing these four beetle species is not warranted at this time. In its 90-day finding on this petition, the USFWS determined that the petition provided substantial information indicating that listing may be warranted for four of the six species: Crescent Dunes aegialian scarab (Aegialia crescenta), Crescent Dunes serican scarab (Serica ammomenisco), large aegialian scarab (Aegialia magnifica), and Giuliani's dune scarab (Pseudocotalpa giulianii). The USFWS also determined that the petition did not provide substantial information indicating that listing the other two species, Hardy's aegialian scarab (Aegialia hardyi) and Sand Mountain serican scarab (Serica psammobunus), may be warranted.
