<paragraph pageId="66" pageNumber="67">Few specimens of this species have ever been collected, and none within the last quarter century; it is known from only a few localities. The Catalina Island Conservancy manages most of Santa Catalina Island and the United States Navy owns San Clemente Island which may afford the species some protection. Nevertheless, I would consider the status of this species likely imperiled due to low abundance and rarity in collections.</paragraph>
