Abstract:
The Sequatchie caddisfly, Glyphopsyche sequatchie Etnier and Hix, is a rare limnephilid caddisfly whose known range is restricted to three sites in the Sequatchie River Valley, Tennessee. The species was discovered in 1994 from Owen Spring Branch, Marion County, approximately 25 air km west of Chattanooga. A second population was discovered four years later in Martin Spring, approximately 19 air km from the type locality. A single individual was discovered from a third site in the Sequatchie Valley in 2010. Due to its reduced range and perceived threats, the species was recognized by the U. S. Fish and Wildlife Service as a candidate for federal listing in 1999. In 2010 and 2011, we initiated a status survey for the species in Tennessee and northeastern Alabama. No additional populations were discovered. The species appears to be stable at the type locality but continues to be rare at the other two sites.
