Occurrence Notes
Stebbins (2003) notes a sight record from Seventy-five Mile Creek in eastern GRCA. However, it is unlikely that only a single sighting of this distinctive species would exist and the authors of the 2005 inventory suggest it may have been erroneous.; Data Source: Persons and Nowak 2005
