Oribatella (Acari, Oribatida, Oribatellidae) of western North America
Bibliographic record
Abstract
The oribatid mite genus Oribatella (Oribatellidae) includes 18 species known previously from North America. Herein, wedescribe 11 new Oribatella species from montane, subarctic, forest and prairie habitats in western North America: O. abmisp. nov., O. banksi sp. nov., O. ewingi sp. nov., O. heatherae sp. nov., O. manningensis sp. nov., O. maryae sp. nov., O.oregonensis sp. nov., O. parallelus sp. nov., O. pawnee sp. nov., O. sintranslamella and O. yukonensis sp. nov.Descriptions of two species (O. heatherae and O. pawnee) include some developmental instars. That of O. yukonensisincludes all instars; nymphs retain dorsocentral setae dm and dp, but the setal morphology changes between larva andnymphs. These immatures bear sclerotized areas on the hysterosoma. Adults of Oribatella oregonensis show distinctsexual dimorphism, with three notogastral setae arising from fused porose areas in the male. We provide new distributionrecords for Oribatella species previously known from North America, including O. arctica Thor, 1930, O. canadensisBehan-Pelletier and Eamer, 2010, O. jacoti Behan-Pelletier, 2011 and O. reticulatoides Hammer, 1955, and remark on O.anomola Grabowski, 1970. We clarify description of the octotaxic system and the interlamellar region in species ofOribatella and discuss variability in hysterosomal sclerotization and setation in immatures. Finally, we give a key to adults of the 29 species of Oribatella now known from North America.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
