The world species of Balcha Walker (Hymenoptera: Chalcidoidea: Eupelmidae), parasitoids of wood-boring beetles
Bibliographic record
Abstract
The world species of Balcha Walker (Hymenoptera: Eupelmidae) are revised, keyed and illustrated. Sixteen species are recognized, including two that are newly classified in the genus, B. reticulata(Nikol’skaya) n. comb. and B. splendida (Girault) n. comb., and eight that are described as new, B. camptogastra n. sp., B. dictyota n. sp., B. enoptra n. sp., B. eximiassita n. sp., B. laciniosa n. sp., B. punctiscutum n. sp., B. reburra n. sp., and B. reticulifrons n. sp. Evidence for the monophyly of Balcha is discussed and the 16 species are segregated into four species groups based on morphological features. Balcha indica (Mani & Kaul) is newly recorded from the eastern United States (Maryland, Michigan, Virginia) as an accidental introduction from the Oriental region and as an adventitious parasitoid of the emerald ash borer, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
