Discussed as Baetis punctiventris. Quote from page 255 in the discussion of Baetis bicaudatus: "Another "two-tailed," trout-stream species of Baetis that may eventually be confirmed from Colorado is B. punctiventris (McDunnough), which has often been incorrectly known as Pseudocloeon edmundsi to Salmon River and Yellowstone fly fishermen." Then in the discussion about Baetis virile, which has since been renamed Plauditus virilis, they note "There remains, however some possibility that it (Plauditus virilis) is either a color variant of B. punctiventris or that it is an undescribed species."
