Salticid spider phylogeny revisited, with the discovery of a large Australasian clade (Araneae: Salticidae)
Bibliographic record
Abstract
DNA sequence data from four gene regions (28S, 18S, 16S-ND1, and CO1) were gathered from 65 jumping spider (salticid) taxa to supplement previously gathered molecular data for the family's phylogeny. The additional taxa are mostly from Australasia and other regions of the Old World. Bayesian and parsimony analyses support a clade, here called the Astioida, representing a large proportion of the Australasian fauna. Included in the Astioida are, for example, the robustbodied Simaetha and Mopsus, the flattened bark-dweller Holoplatys, the delicate foliage-dweller Tauala, the antlike Myrmarachne and the litter-dwelling Neon. One astioid, Rhondes neocaledonicus, is returned to that genus from its placement in Hasarius. Another newly supported clade, the Aelurilloida, includes the aelurillines, the freyines, and the Bacelarella group of genera. Other newly delimited clades are the Philaeus group (Philaeus, Mogrus, Carrhotus and others), the Leptorchesteae (Leporchestes, Yllenus and Paramarpissa) and the Hasarieae (Hasarius, Habrocestum and Chinattus). These results concur with previous discoveries (e.g., Amycoida, Marpissoida) in suggesting that salticid clades are largely restricted to continental regions.

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.
