North American species of Diamphidaxona (Acari: Hydrachnida: Hygrobatidae)
Bibliographic record
Abstract
Members of the genus Diamphidaxona Cook, 1963 are found from southeastern Canada to Argentina, with greatest diversity of species and species groups in the southwestern United States and Mexico. In this paper the three species of Diamphidaxona previously known from North America, D. pallida Cook, D. dolichosoma Cook and D. imamurai Cook, are redescribed. Eleven new species, including D. arizonica sp. nov., D. brevitarsa sp. nov., D. californica sp. nov., D. cavecreekensis sp. nov., D. chihuahua sp. nov., D. chiricahua sp. nov., D. cramerae sp. nov., D. neomexicana sp. nov., D. parvacetabula sp. nov., D. platysoma sp. nov. and D. sabinalensis sp. nov., are also described. North American species are allocated to two subgenera, the nominate subgenus and Diamphidaxonella subgen. nov., for which diagnoses are provided. New distributional data and a key for all North American species are presented.

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; a candidate call from one teacher head, not a consensus.
