Bibliographic record
Abstract
Stipulosina ceroptistylus Yau & Marshall n. sp. (Figs. 12a–e, 13a–f, 14a–d) Description: Body length 1.8–2.8 mm, females on average smaller than males. General color brown but leg parts other than hind femur yellow. Eye height 4.5–5.0× gena height. Mid tibia with an anterodorsal seta at basal quarter, the corresponding posterodorsal seta small and inconspicuous, less than a third as long as anterodorsal seta; anterodorsal, dorsal and smaller posterodorsal setae present at distal 3/4. Second and third costal sectors subequal. Male abdomen: Sternite 5 with a prominent trifid posteromedial area made up of a small, distally narrow central piece subtended by a cup-like lobe and flanked by longer processes with broad basal ventral lobe with long stout setae and a distal bare ventral lobe giving the apex a beak-like aspect; length anterior to trifid posteromedial area 0.5× length of S4. Epandrium with uniform setae. Surstylus deeply divided into elongate, narrow anterior and posterior ventrally directed lobes, both setose but posterior lobe much longer. Cercus small, slightly convex, with two long, stout setae. Ventral lobe of subepandrial sclerite rounded and short. Basiphallus broadly cylindrical, tapered to distiphallus; distiphallus basally cylindrical and heavily sclerotized, dorsally with a straight fork extending to apex of membranous distal portion, membrane finely spiculate ventrally. Postgonite stout, dark; very broad basally, sharply tapered on distal half. Female abdomen: Tergite 8 anteromedially desclerotized; T8 of uniform length. Epiproct three quarters as long as cercus. Spermathecae with scale-like pattern. Etymology: The specific name refers to the deeply cleft surstylus, superficially similar to the surstylus of species in the genus Ceroptera Macquart. 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 debu00195553. Paratypes: Same as holotype (4♂, 4♀, DEBU); Yanayacu Biological Station, 0°3’S, 77°53’W, 2000–2500 m, 25.ix–13.x.2019, T. Yau and S.A. Marshall (15♂, 15♀, QCAZ).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
