W. Wang, HBUARA#2022-77. Etymology. The specific epithet is from the Chinese “ ae (zǔ)”, meaning “elders above paternal generation”; it is in honor of the grandparents of the first author who have given him tremendous love; noun in apposition. Diagnosis. The new species resembles O. feitongae sp. nov. in the body form, the shape of male palp and the presence of a small nick on prolateral side of embolus (Fig. 364), but the males can be distinguished by the absence of apophysis on embolic disc (Fig. 376; vs. AE is present in O. feitongae sp. nov.) and the prolateral process on distal half of embolus that is not obviously triangular (Fig. 361; vs. the process is obviously triangular in O. feitongae sp. nov.); females can be distinguished by the drop-like starting part of copulatory duct (Figs 370–375), whereas the starting part of copulatory duct is inverted triangular in dorsal view of vulva in O. feitongae sp. nov.. Description. Male. Habitus as shown in Fig. 359. Measurements of holotype: carapace length 2.57; abdomen length 2.51; measurements of eyes: AME 0.45, ALE 0.27, PME 0.07, PLE 0.21; measurements of legs: I 4.92 (1.35, 1.05, 1.16, 0.82, 0.54), II 4.04 (1.28, 0.82, 0.76, 0.71, 0.47), III 4.14 (1.31, 0.76, 0.73, 0.81, 0.53), IV 4.61 (1.38, 0.78, 0.99, 0.95, 0.51); leg formula 1432. Body dark, cephalon with yellow setal band on each lateral side and dorsal front area; front edge of clypeus with one row of sparse white setae; dorsal abdomen with dense yellow setae around and on posterior half of axis. Melanic area on legs I–II distinct than III–IV. Palp (Figs 361–363): palpal bulb rather swollen, lobe-like protrusion of tegulum short and stout; embolus straight, short sword-like in ventral view, surface of embolus rough; apophysis on embolic disc absent; basal and median part of RTA wide, distal portion gradually narrowed; pro-ventral hump of tibia pointing pro-ventrally, semicircular in prolateral view (Fig. 362); ventral femoral bump shark fin-like in lateral view (Figs 362–363). Female. Habitus as shown in Fig. 360. Measurements of paratype: carapace length 2.56; abdomen length 2.69; measurements of eyes: AME 0.48, ALE 0.29, PME 0.06, PLE 0.20; measurements of legs: I 3.46 (1.06, 0.81, 0.61, 0.56, 0.42), II 3.53 (1.12, 0.76, 0.67, 0.55, 0.43), III 3.82 (1.20, 0.69, 0.69, 0.77, 0.47), IV 4.51 (1.34, 0.78, 1.00, 0.88, 0.51); leg formula 4132. Coloration like male but setae on cephalon sparse. Epigynum (Fig. 365): area above atria forming triangular concave area; atria oval, close to each other and far away from genital furrow. Vulva (Fig. 366): enlarged area of starting part of copulatory duct drop-shaped; accessory glands (AG) relatively long, distal part pointing upwards; spermathecae dark, one loop of duct formed at dorsal side of basal part of spermathecae. Natural History. All specimens were collected in cracks of rocks, walls, or tree trunks. Distribution. China (Yunnan).

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.
