Patrera tensa resembles P. pellucida by the similar embolus and route of the sperm duct in the tegulum of male palp (as in Figs 22A, 23A, 24B) and having small hood in the female epigynum (as in Figs 22F, 23C, 24F), but differ by the absence of retrolateral basal projection in the cymbium, by the narrow retrolateral tibial apophysis which is fan-shaped at the apex and by the enlarged basal area of the median apophysis in the male palp (Figs 11C–E, 12A, B, 13B–E). Females differs by the epigynum presenting small, triangular atrium, with parallel, not coiled copulatory ducts between the spermathecae (Figs 11F, G, 12C, D). Description. Male (IBSP 138574). Carapace and legs yellow; chelicerae yellow; labium and endites yellow. Abdomen with spots dorsal; ventrally cream (Fig. 11A). Total length 6.5, carapace length 2.9, width 2.4. Clypeus height 0.10.

Variation. Males (n=6): total length 6.1–7.5; carapace length 2.8–3.2; femur I length 4.1–4.4; Females (n=4): total length: 6.2–6.8; carapace length 2.6–2.7; femur I length 2.7–2.9. Distribution.

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.
