Pheidole nasifer Wilson, 2003, new species
Bibliographic record
Abstract
Pheidole nasifer new species Types Mus. Comp. Zool. Harvard. Etymology L nasifer, bearing a nose, referring to the nose-like protrusion of the median clypeal carina of the major in side view. Diagnosis A medium-sized member of the tristis group similar and in various ways to the species listed in the heading, but sharply distinguished as follows. Major: a single "nose" (the median carina of the clypeus) protrudes in side view, not accompanied by the frontal lobes; all of dorsal surface of head except occiput covered by carinulae, with those originating from the frontal lobes and along the frontal carinae turning outward to travel to the sides of the head; pronotal dorsum transversely carinulate; petiolar node from above oval. Minor: propodeal spines reduced to denticles; mesosomal dorsum almost completely covered by transverse carinulae; postpetiolar node depressed, and postpetiole cylindrical in overall shape; occipital margin broad and weakly concave. Measurements (mm) Holotype major: HW 1.16, HL 1.32, SL 0.64, EL 0.18, PW 0.68. Paratype minor: HW 0.56, HL 0.62,. SL 0.56, EL 0.10, PW 0.36. Color Major: concolorous plain medium brown. Minor: body dark brown, appendages medium brown. Range Known only from the type locality. Biology The nest of the type colony contained a cache of small seeds. Figure Upper: holotype, major. Lower: paratype, minor. PERU: vicinity of Tingo Maria, Huauco (W. L. Brown and W. Sherbrooke). Scale bars = 1 mm.
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.
