Abstract
Cheilosia (Cheilosia) orthotricha Vujić & Claussen, 1994 Fig. 50 Cheilosia orthotricha Vujić & Claussen, 1994: 261. Differential diagnosis Cheilosia orthotricha is quite a large species (12–15 mm) characterized by the combination of a bare face, pilose eye, bicoloured legs and posterior margin of scutellum without bristles. It can be distinguished from most other Cheilosia with the same set of characters by the bare or sparsely pilose ventral part of the eye (entirely pilose in similar species). It forms a similar-looking trio with C. canicularis and C. himantopus, but generally in C. orthotricha pile on the pleura straight, unlike pile in C. canicularis and C. himantopus, which is wavy at apex, the pile on posterior anepisternum have straight apex (with wavy apex in the other two species) and face predominantly shiny (slightly pruinose in the other two species). The male genitalia are figured in Vujić & Claussen (1994). Material examined Cheilosia orthotricha was not collected in 2018, but collected in 2023.

Genetics All DNA barcodes of C. orthotricha are clustered together with high support (BS = 99%). Within this cluster, two barcodes from Germany group together (BS = 100%) and five barcodes from Georgia cluster together (BS = 100%). Remarks Reported from the Caucasus, and Georgia, for the first time.Georgian individuals of C. orthotricha are genetically different from European populations (2.43–2.55%). We also found small morphological differences between populations in both regions. Our sample size for populations in both areas is too small to understand this variation, and for now we consider all populations belonging to one species. Biology During our expeditions, collected between 4 May and 9 May at an altitude between 1248 and 1760 m a.s.l. Nearly always found in close vicinity of its food plant Petasites hybridus L. Both sexes sit on leaves of the plant. Distribution Europe, Caucasus (Georgia).

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.
