| Abstract |
The study investigated the taxonomy of three groups of the cladoceran genus Ceriodaphnia in cultures being used by the U.S. Environmental Protection Agency. One taxonomic group, having heavy, triangular denticles in a pecten on the postabdominal claw and very short male antennules, was identified as C. reticulata. The second group, with a heavy, setulated pecten on the claw and long male antennules was identified as C. dubia Richard 1984. The third group was taxonomically nearly identical to C. dubia except that the claw pecten of females sometimes had ovate, sharp teeth rather than comb-like setules, depending upon culture conditions. This was determined to be a hitherto underscribed phenotypic variant of C. dubia, and is designated as C. dubia, toothed-pecten variety. |
