ANNOTATED SYSTEMATIC LIST 



The following list of Harpacticoida (121 species) is 

 arranged systematically in families after Lang (1948, 

 1965), with genera arranged alphabetically within the 

 families and northeastern United States species 

 alphabetically within the genera. The distribution for the 

 northeastern United States is given as well as the world 

 distribution of the species not endemic to the 

 northeastern United States. The species preceded 

 bv * are doubtful records from the northeast.
