Abstract
Cheilosia (Cheilosia) velutina Loew, 1840 Fig. 78 Chilosia velutina Loew, 1840: 33. Chilosia velutina – Stackelberg & Richter 1968: 249. — Stackelberg 1970: 64. — Peck 1988: 119. — Barkalov 1993: 724. — Mengual et al. 2020: 22. Cheilosia velutina Loew, 1848 [sic] – Gujabidze 2002: 245. Differential diagnosis Cheilosia velutina is a member of a group of closely related species, called the proxima group (Vujić et al. 2013) in which the pilose eyes, posterior margin of scutellum with setae, usually partly yellow legs, continuously pilose katepisternum, pruinose sterna and the shape of postgonite are distinctive characters. For a full diagnosis of the Cheilosia proxima group and for figures of the male genitalia of C. velutina, see Vujić et al. (2013). Within the proxima group C. velutina is best identified by the poorly developed facial tubercle, resulting in the face being almost flat between facial tubercle and postclypeus (Fig. 78B, D) (in the other species, facial tubercle well-developed, face in lateral view obviously concave between facial tubercle and postclypeus). Moreover, no other species in the proxima group have the combination of the postpedicel usually orange at least basoventrally and scutum coarsely punctured like in C. velutina. Material examined Species not collected. Genetics DNA barcodes of European specimens of C. velutina cluster together with high support (BS = 100%). Distribution Palaearctic. Within the Caucasus reported from Azerbaijan and Russia.

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.
