Abstract
Amiota oviraptor, sp. nov. Figures 52C–D, 53F–G, 58, 92B DIAGNOSIS: Large fly (ThL 1.56–1.66 mm), dark brown to black; outer paraphysis heavily sclerotized, in lateral view strongly sinuate, anterior portion curving dorsally, posterodorsal portion with 2 posterior facing spines, posteroventral region forming a strong laterally flattened “wing” (posteriorly pointed), the apex with a minute hook; inner paraphysis lost. DESCRIPTION: Large fly (ThL 1.56–1.66 mm), dark brown to black, legs yellow. Frons golden, pruinose. Facial marking large, depth 0.5× width. Cheek wide (EL/CW 11.14–12.5), milky white posteriorly. Palp dark brown. Haltere white. Tergites 1 and 2 lightly colored. Arista: Short, plumose; longest branch D3; A.R. 0.26; 4 longer dorsal, 2–3 short ventral branches; branch D4 pointed mediad; arista trunk with long microtrichia to apex. Male genitalia: Epandrium split medially, middle gap large, membranous; lower third with long setae; small projection anterolaterally. Cercus cylindrical, not grading into surrounding membrane; large membranous region dorsally. Surstylus squarish, ventral half densely covered with setulae; 13–14 short, peglike prensisetae, apices blunt; laterally with barely a lobe. Subepandrial sclerite sclerotized, C-shaped in lateral view, its broad section with muscle attachment scars; subepandrial appendage well developed, vaguely heart shaped in posterior view, apex with minute irregular serrations. Outer paraphysis heavily sclerotized; in lateral view strongly sinuate, anterior portion curving dorsally; posterodorsal portion with 2 posteriorfacing spines; posteroventral region forming a strong, laterally flattened “wing,” posteriorly pointed; apex with a very small, downward pointed hook. Inner paraphysis lost. Aedeagal apodeme roughly trapezoidal, curved nearly 90° in lateral view, width 1.25× length; posterior portion deeply constricted; distal end widely flared, with deep concave depression/emargination. Hypandrium U-shaped; lateral arms thick, winglike ventrally; lateral arm with a strong gonopod, posteriorly pointed. Ejaculatory apodeme relatively small, well sclerotized, 0.6× length of epandrium; flattened end nearly in line with stalk. Head and thorax measurements: (n = 2; Am 1506, 1529): FL/FW 0.69 (0.68–0.70), EL/EW 1.20 (1.18–1.22), EL/CW 11.82 (11.14–12.5), FML/FMW 0.36 (0.34–0.38), PR /RR 0.62 (0.54– 0.70), ThL 1.61 (1.56–1.66 mm). TYPE MATERIAL: Holotype: male: 14 mi. SW. El Salto, Dgo. [Durango] MEX., [23.786449, -105.597725], 8000′, June “9” 1964, J.F. McAlpine, Am 1529, [glued to pin, dissected]. Deposited in the Canadian National Collection (CNC). Paratype: 14 mi. SW. El Salto, Dgo. MEX., 8000′, June “26” 1964, J.F. McAlpine, attracted to man, [dissection lost], 1♂ (Am 1506*, CNC). OTHER MATERIAL EXAMINED: Known only from the type series. ETYMOLOGY: In reference to the lateral view of the fused paraphyses which resemble the “winglike” arm and head of an oviraptorid dinosaur and other birdlike dinosaurs. DISTRIBUTION: Amiota oviraptor is currently known only from the vicinity of the city of El Salto within Durango State in Mexico. COMMENTS: This species exhibits the characteristic behavior of attraction to the eyes and face common to many Amiota.

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.
