Abstract
Chironomus perpulchrum (Mitchell, 1908) (Figs. 1A,D, L, 2C,H) Lauterborniella perpulcher (Mitchell); Johannsen, 1937; ToWnes, 1945. Stelechomyia perpulchra (Mitchell); Reiss, 1990 Kribiodorum perpulchra (Mitchell); Epler et al., 2013 Tendipedini sp. A; Roback (1953), LarVa. Material examined. 1 Le / Pe / Ƌ (on 2 slides): CANADA, Québec, R. Rouge nr. Calumet, 1.v.1980, reared from dead roots of Acer (A. Borkent), CH9121 CNC Ottawa (ZSM). Description (n=1) B.l. 5.1mm, W.l. 2.6 mm. Head. Antenna. Fl1–12 570, Fl13 960, A.R. 1.68. 32 clypeals, 4 aligned verticals. Palpomeres (2–5) 63, 125, 205, 252. Thorax (Fig. 1A). Ac>5, Dc 9 with 1 in humeral position; Pa 4–5, Scts 4. Wing (Fig. 1D) brown with clear base, clear areas in bases and apices of cells r4+5, m1+2, cu, forming two incomplete pale transverse bands. V.R. 1.19. Vein setation: R with 24, R1 with 18, R4+5 with 19–21 in distal 2/3 only. Legs. Apical femora strongly dilated, darkened, bearing dense dark long setae contrasting to pale setae arising from pale cuticle; apical 1/3 to 1/2 of Ta1 darkened (Fig. 1L); other tarsomeres on all legs with apical dark bands, or completely dark on ta3–5 (P1) or only Ta5 uniformly mid-brown. Lengths: P1 1320, 760, 1520, 960, 68, 520, 200; P2 1240, 1060, 640, 280, 200, 140, 100; P3 1460, 1160, 800, 480, 400, 260, 120. Ratios: LR1 2.0, LR2 0.60, LR3 0.53; BV1 1.52, BV2 4.08, BV3 2.0; SV1 1.39, SV2 3.59, SV3 3.78. Foretibial spine 70, tapering, sinuous. Abdomen. Strongly and densely setose, more densely clustered medially, with setae at least 300 long. Genitalia (Fig. 2C,H). TIX with 22 anal tergite setae in mid-tergite, setae stronger antero-medially and weaker posterolaterally, clustered between strong tergal bands. Anal point parallel-sided, downwardly curved seeming a little spatulate, protruding by 50 from squared-off anal tergite. Superior volsella (Fig. 2H) 100 long, curved, with microtrichiose base bearing 10–11 setae, directed posteriorly except median pair directed medially; digitus 60 long curved and tapering evenly to postero-medial directed fine point. Median volsella with 5–6 fine setae arising from tubercle bases forming squat, volsella. Gcx 120, gently rounded, Gst 190, not especially tapered, with rounded apex.

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.
