Abstract
Abstract We propose a higher classification of the lycaenid hairstreak tribe Eumaeini – one of the youngest and most species‐rich butterfly tribes – based on autosome, Lepidopteran Z sex chromosome and mitochondrial protein‐coding genes. The subtribe Neolycaenina Korb is a synonym of Callophryidina Tutt and subtribe Tmolusina Bálint is a synonym of Strephonotina K. Johnson, Austin, Le Crom, & Salazar. Proposed names are Rhammina Prieto & Busby, new subtribe ; Timaetina Busby & Prieto, new subtribe ; Atlidina Martins & Duarte, new subtribe ; Evenina Faynel & Grishin, new subtribe ; Jantheclina Robbins & Faynel, new subtribe ; Paiwarriina Lamas & Robbins, new subtribe ; Cupatheclina Lamas & Grishin, new subtribe ; Parrhasiina Busby & Robbins, new subtribe ; Ipideclina Martins & Grishin, new subtribe ; and Trichonidina Duarte & Faynel, new subtribe . Phylogenetic results from the autosome and Z sex chromosome analyses are similar. Future analyses of datasets with hundreds of terminal taxa may be more practical time‐wise by focussing on the smaller number of sex chromosome sequences (2.6% of nuclear protein‐coding sequences). The phylogenetic classification and biological summaries for each subtribe suggest that a variety of factors affected Eumaeini diversification. About a dozen kinds of male secondary sexual organs with frequent evolutionary gains and losses occur in Atlidina, Evenina and Jantheclina (141 species combined). Females have been shown to use these organs to discriminate between conspecific and nonconspecific males, facilitating sympatry among close relatives. Eumaeina, Rhammina and Timaetina (140 species combined) are overwhelmingly montane with some evidence for a higher incidence of sympatric diversification. Seven Neotropical lineages in five subtribes invaded the temperate parts of the Nearctic Region with a diversification increase in the Callophryidina (262 species). North American Satyrium and Callophrys then invaded the Palearctic at least once each, with a major species‐richness increase in Satyrium . The evolution of litter‐feeding detritivores within Calycopidina (172 species) resulted in an increase in diversification rate compared with its flower‐feeding sister lineage. Atlidina, Strephonotina, Parrhasiina and Strymonina (562 species combined) each contain a mixture of genera that specialize on one or two caterpillar food plant families and genera that are polyphagous. These would be appropriate subtribes to assess how the breadth of caterpillar food plants and the frequency of host shifts affected diversification.

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
