Range extension, ecological notes, and new records of Pycnopsyche indiana (Trichoptera : Limnephilidae) from Florida

New records of Pycnopsyche indiana are reported from Florida. including rec ords from the Florida peninsula that represent a significant southern range extension. The taxonomy and geographic distribution for P. indiana is revi ewed. Southern Gulf Coastal Plain populations are widespread but uncommon, showing a disjunct distribution. In Florida, P. indiana is most often found associated with tannic streams and rivers. Tannic streams with intact broa dleaf riparian vegetation within the southern Gulf Coastal Plain are postul ated as being important refugia for populations of this species. Ecological and biological notes are given for the southern-most known population. Los s of intact riparian broadleaf forests will likely result in negative impac ts on scattered populations of P. indiana within the southern Gulf Coastal Plain.
