Abstract
Cheilosia (Cheilosia) variabilis (Panzer, 1798) Fig. 77 Syrphus variabilis Panzer, 1798: 10. Cheilosia variabilis – Stackelberg & Richter 1968: 249. — Stackelberg 1970: 59. — Barkalov 1993: 714. — Gujabidze 2002: 245. — Mengual et al. 2020: 21 (part). — Żóralski & Bystrowski 2021: 26. Differential diagnosis The combination of eye and face with pile and black legs of Cheilosia variabilis distinguish this species from all other Cheilosia of the region, except for C. borjomi sp. nov., C. melanopa and C. redi. It is similar to C. melanopa and C. redi but on average larger (9–12 mm vs 8–10 mm), with slenderer abdomen, legs all black (base and sometimes apex of tibiae yellow in those of C. melanopa and C. redi), in the male, the ventral part of the metafemur has black setae (with short black pile in C. melanopa and C. redi) and in the female, the metatibia has black pile anterolaterally (yellow in that of C. redi) and scutum with shorter semi-adpressed yellow and black pile and with sparse, longer, more erect black pile (with short erect yellow pile in that of C. melanopa). It is very similar to C. borjomi; see Differential diagnosis of that species for differences. Despite small genetic differences with European populations of C. variabilis, no consistent morphological differences were found. The male genitalia of C. variabilis are figured in Francuski et al. (2009). Material examined Collected in 2018, 2019, 2021 and 2023; see Mengual et al. (2020) for detailed records from 2018. Genetics DNA barcodes of C. variabilis are grouped in one cluster without high support (BS <90%), comprising a group of sequences from European specimens (BS <90%) and another group of sequences with the Caucasian individuals (BS = 95.4%). Remarks Some records of C. variabilis in Mengual et al. 2020 actually are C. borjomi sp. nov., and are reported as such in the account of C. borjomi. Biology During our expeditions, collected between 30 April and 26 June at an altitude between 751 and 2300 m a.s.l. Often found near forest or shrubs or near tall vegetation in meadows. Males sit on leaves of trees and both sexes visit a variety of flowers, often white umbellifers. Distribution Western and Central Palaearctic, into western Siberia. Distribution within the Caucasus difficult to assess because previous records could also be Cheilosia borjomi sp. nov., but reported from Armenia, Georgia 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.
