Maxillolabial complex in scelionids (Hymenoptera: Platygastroidea): morphology and phylogenetic implications
Bibliographic record
Abstract
The Platygastroidea is a highly diverse group of small to minute parasitoid wasps. Despite the reduced size, the morphology of the maxillolabial complex of scelionids is very diverse and phylogenetically informative. 81 characters are scored for 129 genera (representing 75% of the total number of known extant genera of scelionids), as well as for seven outgroup taxa. All taxa examined are illustrated with images, SEM micrographs and/or line drawings. Phylogenetic trees resulting from analyses conducted in TNT under various settings were not fully resolved, but some relationships were repeatedly retrieved. The Platygastroidea are usually corroborated. Nixoniini, Sparasionini,PlaumannionandHuddlestoniumare frequently retrieved as the most basal platygastroid lineages.PsixandParatelenomusoften form a monophyletic group close to Gryonini. The Scelioninae, Teleasinae and Telenominae are not supported as monophyletic. However, some major scelionid clades are frequently retrieved, but these are not recognized in the current classification of Platygastroidea. The evolution of the palpal formula, highly variably in scelionids, and previously used in platygastroid systematics, is explored. The number of maxillary palpomeres in the ground plan of platygatroids is probably five, that of labial palpomeres two or three, given the variation among basal scelionids. Our study provides relevant information for resolving the phylogeny of the Platygastroidea, but additional character sources have to be explored to obtain a robust phylogenetic hypothesis.

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.
