Notes Glossary
  • Nearly extinct in U.S.; known in CA from only four occurrences. The historical report from SDG Co. likely constitutes a misidentification. Black Lake Cyn. and Little Oso Flaco Lake populations not seen in 1998, possibly extirpated (Information in the preceding sentences may need to be altered pending verification of the known occurrences of this taxon). Seriously threatened by habitat loss, erosion, and Eucalyptus that may be altering hydrology at Black Lake Cyn. Recovery plan prepared by USFWS in 1994. See Proceedings of the American Academy of Arts and Sciences 11:147 (1876) for original description, and Novon 8(2): 124-126 (1998) for revised nomenclature.

      * Presumed extirpated
      ? Uncertain about distribution or identity
      ?* Uncertain about distribution, but presumed extirpated if once present
      (?) Occurrence confirmed, but possibly extirpated
