Bibliographic record
Abstract
Demeijerea spinulata sp. n. (Fig. 1 A–C) Type material. Holotype male, CANADA: Manitoba, Lake Winnipeg, 3 km off McCreary Island, 15.vii. 1969, P.S.S. Chang (CNC). Paratype: Old Fishing Dock, 1 male, 16.vi. 1971, E. Johnson & M. Roberts. Diagnostic characters. The male imago is characterized by a pale greenish coloration with pale orange-brown markings, an AR of about 3.5, distinct frontal tubercles, angular corners at each side of antepronotum, about 14 sensilla chaetica on ta1 of p2, a distinctly spatulate anal point, and weak apical spines on the superior volsella. Etymology. From Latin, spinula, small thorn, and -atus, equipped with, referring to the weak apical spines on the superior volsella. Description. Male imago (n = 1–2) Total length 7.76–8.22 mm. Wing length 3.92–4.30 mm. Total length/wing length 1.91–1.98. Wing length/ length of profemur 2.67–2.75. Coloration pale greenish with pale orange-brown markings. Head. AR 3.49. Temporals 25–29. Clypeus with 27–34 setae. Tentorium 280–290 µm long. Stipes 236–260 µm long. Frontal tubercles (Fig. 1 B) 19–35 µm long, 18 µm wide. Palpomere lengths (in µm): 66–90, 83–88, 251– 272, 212–252, 356–408. Thorax (Fig. 1 A). Antepronotum bare, corners angular. Dorsocentrals 30–36, acrostichals absent, prealars 7– 10. Scutellum with 29–32 setae. Wing. VR 1.01–1.02. Brachiolum with 2–4 setae, R with 15–16, R1 with 19–22, R4+5 with 14–17 setae. Squama with 30–32 setae. Legs. Sensilla chaetica 14 at 0.27–0.74 of ta1 of p2, none on p3.

Anal point 140–156 µm long, distinctly spatulate. Gonocoxite 325–366 µm long, superior volsella with small apical spines; gonostylus 246–252 µm long. HR 1.32–1.45, HV 3.15–3.26. Remarks. This species is close to Demeijerea abruptus (Townes) (Townes 1945:138) and D. obreptus (Townes) (Townes 1945:139). It combines the AR of Demeijerea obreptus with the angular antepronotum of D. abruptus, while the frontal tubercles vary between the large type of D. abruptus and the smaller one of D. obreptus. However, it appears to differ from both species in the more spatulate anal point and in the presence of spines on the superior volsella. However, Heyn (1992: 133) mentions that both D. abruptus and D. obreptus, as in this species, lack the wide median notch on the antepronotum and probably should not be included in Demeijerea. The anal point and hypopygium is quite similar to the specimens mentioned by Gillespie (1974: 143 fig. 50) under D. brachialis as possibly being a new species and may be identical.

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.
