A new genus of fungus-inhabiting mites of the family Blattisociidae (Acari Mesostigmata Phytoseioidea) from Costa Rica, with an updated key to genera of the subfamily Blattosociinae
Bibliographic record
Abstract
The genus Discoseius gen. nov. is described, based on adult females of one newly described species collected from one sample of bracket fungi in Costa Rica. These ovoid mites bear a pair of large, pliable, disclike structures of unknown function, which flank a ventrianal shield that is strangely formed to accommodate the discs ventrally on the opisthosoma. Such uniquely formed structures have been found otherwise only in females of the monobasic eviphidid genus Canestriniphis, from specimens phoretic on erotylid beetles that live in bracket fungi. As female Discoseius are endowed with a sperm access system of the more derivative phytoseioid-type, while female Canestriniphis retain the sperm access system of the plesiomorphic laelapoid-type, this similarity is thought to be convergent. An updated key to the world genera of the subfamily Blattisociinae is presented to accommodate this and another recently proposed genus.

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.
