Occurrence of Diaphanosoma fluviatile Hansen 1899 (Cladocera : Sisidae) in two reservoirs in central Texas

摘要

We report the cladoceran Diaphanosoma fluviatile Hansen 1899 in Lake Waco and Lake Mexia, two reservoirs located in central Texas. This species is formerly known from Central and South America and only recently was reported from some locations in Louisiana and Florida, and from the state of Veracruz, Mexico. Our new records represent a westward expansion of records previously documented in the Southern United States.
