The harvestman genus Taracus Simon 1879, and the new genus Oskoron (Opiliones: Ischyropsalidoidea: Taracidae)
Bibliographic record
Abstract
The ischyropsalidoid genus Taracus Simon 1879 is reviewed and all previously named species are redescribed. Taracus nigripes Goodnight & Goodnight, 1943 is synonymized with T. packardi Simon 1879, and T. malkini Goodnight & Goodnight 1945 with Oskoron spinosus (Banks) 1894; the type locality of T. gertschi Goodnight & Goodnight 1942 is corrected from "eastern Oregon" to Rose Lake, Idaho, based on original labelling. The following new species of Taracus are described: T. carmanah (Vancouver Island), T. marchingtoni (Oregon), T. taylori, T. spesavius (both Nevada), T. timpanogos (Utah), T. audisioae, T. ubicki, and T. fluvipileus (all California). A new genus Oskoron is based upon O. spinosus (Banks) 1894, originally described in Taracus, and also includes two new species, O. brevichelis (Oregon, Washington) and O. crawfordi (Washington). New locality records extend the known distribution of Taracus to the Canadian provinces of Alberta and British Columbia and the US states of Montana, Wyoming, Utah, Nevada and New Mexico. Schönhofer's (2013) proposal of a family Taracidae for Taracus, Hesperonemastoma Gruber 1970 and Crosbycus Roewer 1914 is discussed.

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.
