Abstract
Cheilosia (Cheilosia) proxima (Zetterstedt, 1843) Fig. 57 Eristalis proxima Zetterstedt, 1843: 792. Cheilosia proxima – Tóth 1986: 94. — Peck 1988: 114. — Barkalov 1993: 700. — Barkalov & Mutin 2018: 483. — Mengual et al. 2020: 19. Differential diagnosis Cheilosia proxima 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 see Vujić et al. (2013). The male genitalia of C. proxima are figured in Vujić et al. (2013).Within the proxima group, C. proxima is most similar to C. gigantea. For differences, see the Differential diagnosis of C. gigantea. Material examined Collected in 2018, 2019, 2021 and 2023; see Mengual et al. (2020) for detailed records from 2018. Genetics DNA barcodes of C. proxima from the Caucasus appear clustered in three distinct groups with high support (BS = 99.8%; BS = 100%; BS = 100%). Two of these groups comprise only Caucasian individuals and the third has European and Caucasian specimens. For each group a male is portrayed in Fig. 57 A–C. Remarks Specimens from all three distinctly different barcoding groups are also morphologically distinct, they often occurred at different locations, habitats and times of the year, and they could represent three distinct species. However, when testing these groups morphologically against European material, European specimens show a wide variation with intermediate looking specimens. Due to the lack of extensive genetic samples in Europe it remains unknown if the variation found in European specimens of C. proxima might be correlated with some genetic difference as well or not. More molecular data is needed to properly assess the intraspecific and interspecific variability of this very variable and wideranging species. Biology During our expeditions, collected between 4 May and 8 July at an altitude between 1090 and 2700 m a.s.l. A species found in meadows and clearings near forest in the lower montane zone to alpine meadows above the treeline, but phenology and habitat (elevation niche) differ between the barcoding clusters. Distribution Palaearctic.

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.
