Taxonomic revision of Bracalba Dodd (Hymenoptera, Platygastridae s.l.), a parasitoid wasp genus endemic to Australia
Bibliographic record
Abstract
The endemic Australian parasitic wasp genus Bracalba (Hymenoptera: Platygastridae) is revised. Sixteen species are recognized: B. cuneata Dodd, B. laminata Dodd and B. nigrescens (Dodd) are redescribed and thirteen new species are recognized; B. clavata Burks, sp. n., B. globosa Burks, sp. n., B. hesperia Burks, sp. n., B. intermedia Burks, sp. n., B. magnirubra Burks, sp. n., B. parvirubra Burks, sp. n., B. pinnula Burks, sp. n., B. plana Burks, sp. n., B. propodealis Burks, sp. n., B. sculptifrons Burks, sp. n., B. sparsa Burks, sp. n., B. tricorata Burks, sp. n., and B. tridentata Burks, sp. n. The genus is found continent-wide but mostly south of the Tropic of Capricorn, and with the highest species diversity occurring in the Pilbara and south-western regions of Western Australia. The hosts of Bracalba are unknown but specimens reared from eggs confirm that the genus is associated with orthopteran hosts. A preliminary phylogeny of species did not indicate that species groups were monophyletic, but they are retained despite paraphyly because they are convenient for specimen identification.
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.
