Abstract
Abstract A phylogenetic analysis and classification are provided for the bee subfamily Xeromelissinae based on 248 morphological characters, many of which are novel and illustrated. A total of 47 ingroup species was included in the analysis, representing at least two divergent members from each described genus or subgenus and seven taxa which did not readily fall within previously described subgenera. Three most parsimonious trees were found (length, 1508; consistency index, 40; retention index, 70). The result shows that Xeromelissa renders Chilimelissa paraphyletic, and the 20 known Chilimelissa species are reassigned to Xeromelissa , giving the following new combinations: X. luisa (Toro & Moldenke) (this is the type species of Chilimelissa ), X. mucar (Toro & Moldenke), X. xanthorhina (Toro), X. brevimalaris (Toro), X. rosie (Toro and Packer), X. laureli (Toro and Packer), X. chusmiza (Toro), X. longipalpa (Toro), X. pedroi (Toro & Moldenke), X. australis (Toro & Moldenke), X. chillan (Toro & Moldenke), X. farellones (Toro & Moldenke), X. machi (Toro), X. minuta (Toro & Moldenke), X. nortina (Toro & Moldenke), X. sielfeldi (Toro & Moldenke), X. obscura (Toro & Moldenke), X. irwini (Toro & Moldenke), X. nolanai (Toro & Moldenke) and X. rozeni (Toro & Moldenke). Group support was estimated using symmetric resampling and group supported/contradicted (GC) ratios, which compare the frequency of each most parsimoniously resolved clade with the alternative arrangement that was most commonly found in resampling. Relationships among subgenera for Chilicola are weakly supported. By contrast, when three previously synonymized subgenera ( Stenoediscelis, Heteroediscelis and Oediscelisca ) are resurrected, there is good support for all subgenera (GC ≥ 99), except two: a paraphyletic Oediscelis and a polyphyletic Anoediscelis . Both of these subgenera became monophyletic following successive approximations character weighting. Four distinctive new subgenera are described: Unicarinicola Packer subgen.n. , Obesicola Packer subgen.n. , Capitatiscopa Packer subgen.n. and Toroediscelis Packer subgen.n. , and a revised key to the subgenera of Chilicola is provided.

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
