Abstract
Euochin bethunei sp. nov. (ƦĖḋƙẅss) Figs 4–18 Type material. Holotype: ♁ (MHBU-ARA-00022291), CHINA: Hunan Province, Yongzhou City, Dongan County, Damiaokou Town, Shunshan Park, Ehuangxi (kěUDZHƜȑȁđṖĀ), 26.416301°N, 111.0356687°E, 694 m a.s.l., 8 October 2015, leg. C. Jin, X. Guo & J. He. Paratype: 1♀ (MHBU-ARA-00025229), same data as holotype. Etymology. The specific epithet is in honor of a prominent internationalist from Canada, Dr. Henry Norman Bethune, who saved numerous Chinese soldiers during World War II and is widely commemorated by the people of China. Diagnosis. The males resemble Euochin bulbus (Bao & Peng, 2002) in genitalic features, but can easily be distinguished by the non-furcated retromarginal tooth of the chelicera and the tubular form of the embolus (Figs 8, 9–12, 15; vs. the compound retromarginal tooth of four cusps and the ribbon-like embolus in E. bulbus, see Bao & Peng 2002: fig. 14; Zha et al. 2014: figs 16–17, 19–20). The male palp is also like that of Euochin yaoi Wang & Li, 2021, but differs by the robust embolus and thin RTA (vs. thin embolus and strong RTA in E. yaoi, see Wang & Li 2021: figs 2B–D). The female epigyne is similar to that of E. bulbus, but can be recognized by the obviously smaller epigynal window and accessory gland (Figs 13, 17; see Zha et al. 2014: figs 14, 21). Description. Male. Habitus see Figs 4, 6. Carapace length 1.518; abdomen length 1.390. Eye measurements: AME 0.289, ALE 0.229, PME 0.067, PLE 0.190. Leg measurements: I 2.413 (0.813, 0.381, 0.559, 0.326, 0.334), II 2.276 (0.756, 0.354, 0.483, 0.364, 0.319), III 2.425 (0.807, 0.311, 0.483, 0.481, 0.343), IV 2.847 (0.853, 0.361, 0.614, 0.640, 0.379); leg formula: 4312. Color in ethanol: carapace dark. Abdomen dark, with light bands and patches. Chelicera (Fig. 8) with two promarginal and one retromarginal teeth. Palp (Figs 9–12, 15–16): tibia and cymbium with long white setal tuft dorsally; embolic disc circular, embolus relatively short and thick, tube-like, with notably large opening of sperm duct at tip; cymbial flange narrow but obvious; RTA short, dorsally margined with laminate process. Female. Habitus see Figs 5, 7. Carapace length 1.486; abdomen length 1.452. Eye measurements: AME 0.283, ALE 0.214, PME 0.062, PLE 0.194. Leg measurements: I 2.177 (0.747, 0.345, 0.490, 0.292, 0.303), II 2.004 (0.694, 0.346, 0.407, 0.295, 0.262), III 2.350 (0.831, 0.342, 0.443, 0.442, 0.292), IV 2.869 (0.871, 0.336, 0.637, 0.628, 0.397); leg formula: 4312. Color in ethanol: similar to that of male, but lighter in coloration. Chelicera as in male. Epigyne (Figs 13–14, 17–18): diameter of epigynal window less than that of spermatheca; median septum hourglass-like; copulatory opening located antero-centrally on margin of epigynal window; copulatory duct with obvious accessory gland; spermatheca ovoid, bottom close to genital furrow. Distribution. China (Hunan).

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.
