Abstract

The distribution of <i>Cenocorixa bifida</i> (Hung.) and <i>C. expleta</i> (Uhler) in British Columbia is summarized. The distribution pattern in a series of inland saline lakes in the central interior of the province is described. All water bodies are in the flight range of the two species, and seem to be colonized by them at random. However, <i>C. expleta</i> occurs and breeds only in saline waters, whereas <i>C. bifida</i> lives and breeds in fresh and moderately saline environments. <i>C. expleta</i> has been found only in waters with a conductivity between 3,900 and 29,000 micromhos/cm. (at 25∞C): <i>C. bifida</i> occurs only in waters with a conductivity between 20 and 20,000 micromhos/cm. The distribution appears to be correlated with salinity and not with other features of the environment such as area of water body, mean depth, maximum depth, etc.
