Bibliographic record
Abstract
Stipulosina barbistylus Yau & Marshall n. sp. (Figs. 9a–e, 10a–g, 11a–d) Description: As described for S. amphibarba n. sp. except as follows: Male abdomen: Trifid posteromedial area with small clusters of setae on each side of center piece; longer processes flanking center piece long-setose on distal half inner margin. Cercus length 0.6–0.7× surstylus length. Ventral lobe of surstylus broad and flat, densely long-setose at distal half; dorsomedial lobe small, apex with a few stout setae followed by tight rows of setae along margin. Distiphallus cylindrical with dorsolateral edges strong and corrugated; apex membranous. Postgonite stout, broad basally and tapered apically. Female abdomen: Tergite 8 posteromedially desclerotized; medial and lateral lengths subequal. Length of epiproct 0.5× length of cercus. Spermathecae irregularly crinkled. Etymology: The specific name refers to the dense “beard” of long distal setae on the surstylus. Type material: Holotype (♂, QCAZ): ECUADOR: Napo: SierrAzul Reserve, 14 km W Cosanga, 2200 m, 0°40’55”S, 77°56’9”W, in bamboo stipules, 11.v.2002, S.A. Marshall debu00195526. Paratypes: ECUADOR: Napo: Yanayacu Biological Station, 0°36’S, 77°53’W, 2000–2500 m, 25.ix–13.x.2019, T. Yau and S.A. Marshall (63♂, 55♀, QCAZ); same as previous specimens but the female and male were taken in copula (1♂, 1♂, QCAZ); ditto, ridge, ex. Chusquea scandens stipules (1♀, QCAZ); same as previous specimens but on Rhipidocladum racemiflorum (1♀, QCAZ). Comments: The one specimen of this species collected from Rhipidocladum racemiflorum is the only specimen of the genus known from a species of bamboo other than Chusquea scandens. That specimen was found on a stem rather than in a stipule and it is unlikely to represent a close association. The R. racemiflorum on which the specimen was found on was close to C. scandens, and no further Stipulosina specimens were found in an extensive search of nearby R. racemiflorum.

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.
