The species of Chalcidoidea (Hymenoptera) introduced to North America for biological control of the cabbage seedpod weevil, and the first recovery of<i>Stenomalina gracilis</i>(Chalcidoidea: Pteromalidae)
Bibliographic record
Abstract
Abstract The species of Pteromalidae (Chalcidoidea) introduced to British Columbia, Canada, from Europe in 1949 asTrichomalus fasciatus(Thomson, 1878),Xenocrepis puraMayr, 1904, andHabrocytussp. for classical biological control ofCeutorhynchus obstrictus(Marsham, 1802) (Coleoptera: Curculionidae) are shown to be misidentifications ofTrichomalus perfectus(Walker, 1835),Mesopolobus morys(Walker, 1848), andStenomalina gracilis(Walker, 1834), respectively. Species reared subsequently from seedpods ofBrassicaspp. (Brassicaceae) in British Columbia and reported in the literature under the first three names are shown to be misidentifications of, respectively,Trichomalus lucidus(Walker, 1835),Mesopolobus moryoidesGibson, 2005, and one or both ofPteromalus puparum(L., 1758) andT. lucidus. There is no evidence that eitherT. perfectusorM. morysestablished in North America, butS. gracilisis newly recorded from southern British Columbia based on specimens reared from Brassicaceae seedpods in 2004 and 2005.

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.
