Genus Camptocercus (Cladocera: Anomopoda: Chydoridae) in North America
Bibliographic record
Abstract
Genus Camptocercus is represented in North America by four species. Camptocercus rotundus Herrick, 1882 is proved to be a valid species and is redescribed here. C. rotundus differs from its sibling species, neotropical C. dadayi Stingelin, 1913, in morphology of the postabdominal claw, presence of posteroventral denticles on valves, and morphology of the male postabdomen. C. rotundus is distributed in South Canada and North USA from Pacific to Atlantic coast, whereas C. dadayi is found in Mexico and South-East USA. C. oklahomensis Mackin, 1930 is found in Central USA. C. streletskaye Smirnov, 1998, previously known from Chukotka and Magadan Area of Russia, was found in Alaska for the first time.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
