        | Distinguishing Characteristics | 
      
      
                    
          -  Middle pecten of postabdominal claw stout and
              long, largest at least three times as long as distal pecten.          
 
          -  Ocellus
              present.          
 
          -  Optic vesicle does	not touch margin of head.          
 
          -  Ventral
              margin of head more or less straight.          
 
          -  Dorsal spinules long,
                        interspinule distance less than 1.5 times the spinule
              length.          
 
          -  Middle pecten of postabdominal claw with 3-7
              teeth.          
 
          -  Head and valves no more than 2 mm in length.

              - Easily
                    confused with Daphnia catawba except for spinules.
 
              -  Molecular evidence suggests a close relationship between Daphnia schodleri and Daphnia pulicaria (Hebert 1995).
