A new tribe of tarsonemid mites (Trombidiformes: Heterostigmatina) parasitic on tetrigid grasshoppers (Orthoptera)
Bibliographic record
Abstract
Podotarsonemini tribe nov. (Tarsonemidae: Acarapinae), with one nominate genus Podotarsonemus gen. nov., is proposed for seven new species of tarsonemid mites collected from the hindwings of pygmy grasshoppers of the family Tetrigidae (Orthoptera). The new tribe is placed within the tarsonemid subfamily Acarapinae on the basis of several morphological synapomorphies, as well as on parasitism of insects. In light of this new tribe, a revised description of the Acarapinae is provided, as are full tribal, generic and species descriptions for the Podotarsonemini, and a key to species. In view of Podapolipidae, the sister family of Tarsonemidae, consisting entirely of obligatory parasitic mites, the distinction between the two constituent sister families of Tarsonemoidea as well as the ancestral feeding habits of that superfamily are considered. These mites and their host grasshoppers were collected from Bolivia, Ecuador, Honduras, southern India, Japan, Papua New Guinea, South Africa and two localities in north-eastern Australia. This distribution suggests that the Podotarsonemini are an ancient lineage of Tarsonemidae that radiated on the Gondwanan Tetrigidae during the Jurassic.

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.
