The new Andean jumping spider genus Urupuyu and its placement within a revised classification of the Amycoida (Araneae: Salticidae)
Bibliographic record
Abstract
Urupuyu gen. nov. is described for three new species of small black jumping spiders from the cloud forests of Ecuador: Urupuyu antisana sp. nov. (type species), U. edwardsi sp. nov., and U. occidentale sp. nov. Phylogenetic analyses with DNA sequences (28S, actin 5C, wingless, 16SND1 and CO1) indicate Urupuyu is closely related to the huriine amycoids Hurius and Scoturius, a placement also supported by morphological traits. Our phylogenetic analysis serves to clarify the relationships within the Amycoida in general, leading to our proposing a revised classification for the group, with subfamilies Gophoinae, Sitticinae, Bredinae subfam. nov., Scopocirinae, Thiodininae, Sarindinae, Huriinae, Simonellinae, and Amycinae. We confirm the marpissine-like Breda belongs within the Amycoida. The phylogeny implies that ant mimicry has evolved at least twice (simonellines and sarindines) and probably a third time (Atomosphyrus in the thiodinines) within the Amycoida. The following new synonymies are proposed for suprageneric names: Hyetusseae Simon, 1903 and Arachnomureae Mello-Leitão, 1917 = Thiodininae Simon, 1901; Zunigeae Simon, 1901 = Sarindinae Simon, 1901; Synemosynae Banks, 1892 = Simonellinae Peckham, Peckham & Wheeler, 1888; Magoninae Petrunkevitch, 1928 = Amycinae F.O.P.-Cambridge, 1900.

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.
