Abstract
Amiota avipes, sp. nov. Figures 34A–B, 37A, 38B, E, G, I, 87A DIAGNOSIS: Medium-sized fly (ThL 1.17– 1.24 mm), dark blackish brown fading lighter ventrally; facial marking thin, width 0.25× length; characteristic markings on postpronotal lobe and under wing base small, fading near margins; surstylus with short secondary row of 4 prensisetae; outer paraphyses symmetrical, short, stout, heavily sclerotized, with 2 short apical spines, winglike basal projection, pointed laterally; inner paraphysis lost; length of ejaculatory apodeme equal to height of epandrium. DESCRIPTION: Medium-sized fly (ThL 1.17– 1.24 mm), dark blackish brown fading to lighter ventrally, including katepisternum; legs light yellow. Characteristic markings on postpronotal lobe and under wing base small, fading near margins. Frons dark blackish brown, black near ptilinal suture, overall with faint bluish pollinosity. White facial marking thin, width 0.25× length. Cheek relatively wide (EL/CW 9.5–11), yellowish. Palp yellow. Tergites 1 and 2 lightly colored. Arista: Medium, plumose; longest branch D4; A.R. 0.35; 7 dorsal branches, grading to shortest one apically; 3–4 short ventral branches; no branches pointed significantly mediad or laterad; arista trunk with mediumlength microtrichia to apex. Male genitalia: Epandrium dorsally complete, ventral margin in this area graded into membrane below; row of ~6 setae leading near posterior margin. Cercus long, pendulous, dorsally grading into membrane and epandrium; lateral margins of cercus discrete; cercus large, occupying virtually all space surrounded by epandrium. Surstylus with even row of 8–9 prensisetae, apices blunt; second row of 4 prensisetae dorsally, apices slightly pointed, widely spaced; setulae along ventral margin and midpoint of surstylus. Subepandrial sclerite well developed; subepandrial appendage pyramidal, pointed at tip. Outer paraphysis laterally flattened, heavily sclerotized, short, stout, with 2 pointed apical lobes and small group of sensilla at base of lower lobe; low carina immediately basal to group of sensilla; winglike basal projection, with faint distal striations, oriented laterally. Inner paraphysis lost. Aedeagal apodeme constricted on all sides, curved 90° in lateral view; basal margins wider than distal end. Hypandrium circular, apex with small gap; lateral arms thick, bulging outward anteriorly and posteriorly; membranous connection with 2 pairs small membranous lobes between lateral arms and paraphyses. Ejaculatory apodeme as long as height of epandrium, stalk thick. Head and thorax measurements: (n = 3; Am 1453, 1496, 1514) FL/FW 0.50 (0.45–0.53), EL/EW 1.27 (1.25–1.29), EL/CW 10.3 (9.5–11), FML/ FMW 0.26 (0.23–0.29), PR /RR 0.48 (0.44–0.50), ThL 1.20 (1.17–1.24 mm). TYPE MATERIAL: Holotype: male: 14 mi. SW. El Salto, Dgo. [Durango] MEX., [23.786449, -105.597725], 8000′, June “26” 1964, J.F. McAlpine, attracted to man, Am 1453, [glued directly to pin, dissected]. Deposited in the Canadian National Collection (CNC). Paratypes: 14 mi. SW. El Salto, Dgo. [Durango] MEX., 8000′, June “9” 1964, J.F. McAlpine, attracted to man, 2♂ (Am 1496*, 1514*, CNC). OTHER MATERIAL EXAMINED: Known only from the type series. ETYMOLOGY:Formed from Latin avis for “bird” and pes for “foot.” Used as a noun in apposition. In reference to the paraphyses, in lateral view, resembling an outstretched bird’s foot. DISTRIBUTION: Amiota avipes is currently only known from Durango State. 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.
