Abstract
The southeast Asian genus Eupoa includes small salticid spiders with unusual palpi. Two new species of the genus are described. Two morphological characters (presence of a median apophysis in the male palp and of a tarsal claw in the female palp) suggest it is excluded from the main clade of salticids (the Salticoida). Sequences of nuclear and mitochondrial gene regions (28S, 18S, 16S–ND1, CO1), analyzed by parsimony and Bayesian methods, agree that Eupoa is a basal (non-salticoid) salticid, but fail to find a clear placement. Eupoa may represent a deep-branching lineage long separate from the lyssomanines, spartaeines, and other basal groups.

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
