Abstract
Genus Pachyseius Berlese, 1910 Pachyseius Berlese, 1910a: 255. Type species Pachyseius humeralis Berlese, 1910, by original designation. The genus Pachyseius was proposed by Berlese (1910a), but has sometimes been considered as a synonym of Neoparasitus Oudemans, 1901 in the family Neoparasitidae Oudemans, 1939, for example by Vitzthum (1942) and Baker & Wharton (1952). Evans (1957a) placed Pachyseius as a separate genus in a very broad and heterogeneous family Neoparasitidae. Later Evans & Till (1979) placed this genus in the family Pachylaelapidae, but Karg (1971, 1993) placed Pachyseius in the family Macrochelidae rather than the Pachylaelapidae. Karg (1971) proposed a separate tribe Pachyseiini Karg, 1971 for the genus Pachyseius, primarily because of the simple form of the epistome, short dorsal setae, straight peritremes, and fused ventral and anal shields. Although most other authors have placed Pachyseius in the family Pachylaelapidae, the systematic position of the genus in the family seems to be fragile and provisional. Mašán (2007a) placed it in the subfamily Pachyseiinae, and that usage is followed here. The relationship of Pachyseius to the other genera of Pachylaelapid is unclear. On the basis of the recently described species (Mašán & Mihál, 2007), it appears that the general evolutionary trend in Pachyseius is towards increased sclerotisation, including fusion of some ventral shield components to form a contiguous exopodalperitrematal complex, a sternal-metasternal complex, and abnormally large metapodal platelets widely abutting the parapodal platelets and ventri-anal shield. Pachyseius is distributed exclusively throughout the Palaearctic region, except that Pachyseius humeralis may have been introduced into Australia by human activities (Halliday, 2001), and unidentified species have been collected in northern Australia (Lindquist et al., 2009) and Canada (Broadbent & Tomlin, 1979). It currently comprises 17 known species from Europe, Russia, China and Japan.

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.
