Abstract
The taxonomy of the North American Gymnodamaeidae is currently intractable, because (1) the adults are covered in a thick, ornamented cerotegument that provides useful characters, but that obscures the cuticle; (2) many descriptions appear to be based on newly moulted or cleared specimens and are incomplete or contain misinterpretations; and (3) there is considerable disagreement in the literature about valid genera and generic limits, leading some authors to sink some or all of the North American genera into Gymnodamaeus s.l. Several nomenclatorial problems have added to the confusion. In this paper I use new diagnoses to demonstrate that seven previously described genera based on North American species can be separated from Gymnodamaeus s.s. and provide a key to distinguish them. I clarify the correct publication dates for Paschoal’s genera and after consultation with the original author, propose replacements for two of these generic names that are preoccupied: Donjohnstonella nom. nov. for Johnstonella Paschoal and Roynortonella nom. nov. for Nortonella Paschoal. New Canadian provincial distribution records are provided for Gymnodamaeus cf. ornatus Hammer (AB), Jacotella quadricaudicula (Jacot) (AB, ON), Joshuella agrosticula Paschoal (AB, YK), and Pleodamaeus plokosus (Woolley & Higgins) (AB). Finally, I discuss the similarity between the cerotegumental pustules in the Gymnodamaeidae and the epicuticular wax crystalloids on the leaves of plants such as the water lotus (Nelumbo nucifera Gaertn.) and suggest that they may have a similar water repellent “Lotus-effect.

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 it
