Abstract
Phylogenetic relationships of the Sphaerophoria lineage (Sphaerophoria Le Peletier & Audinet-Serville and related genera) were inferred based on molecular characters, with the specific aim to infer the phylogenetic placement of the Afrotropical Sphaerophoria species and Loveridgeana beattiei van Doesburg & van Doesburg. Three molecular markers were used, i.e., the mitochondrial protein-coding gene cytochrome c oxidase subunit I (COI) and the nuclear 28S and 18S ribosomal RNA genes. The Sphaerophoria lineage genera Exallandra Vockeroth and Loveridgeana were resolved within the genus Sphaerophoria, and the Indomalayan Eosphaerophoria Frey was placed sister to Citrogramma Vockeroth, both related to a large species radiation from the New World. Fazia Shannon and Allograpta Osten Sacken were recovered as non-monophyletic. Our results recovered two different Fazia clades with dissimilar natural history resulted from our analyses, and Allograpta species were resolved into two clades, one with Nearctic and Neotropical species and a second clade with species from Oceanian, Indomalayan and Afrotropical Regions. Exallandra is considered a subgenus of Sphaerophoria, S. (Exallandra) stat. rev., and Sphaerophoria cinctifacies (Speiser) n. comb. a member of this subgenus together with S. loewii Zetterstedt. A new Sphaerophoria subgenus is designated S. (Loveridgeana) stat. rev. to include S. beattiei n. comb. and the South African species, i.e., S. quadrituberculata Bezzi, S. retrocurva Hull, and S. aff. retrocurva. Based on their phylogenetic distinctiveness, functional traits, and ecological relevance we do recommend further ecological study and protection efforts for this Afrotropical group of pollinators.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
