Diverse scelionid wasps in Early Cretaceous amber from Spain (Hymenoptera: Platygastroidea)
Bibliographic record
Abstract
Platygastroid wasp diversity in Álava amber is reviewed.Platygastroids are the most numerous group of Hymenoptera in Spanish amber, a pattern typical for many Cretaceous amber deposits, with species of the superfamily sometimes more abundant than all other arthropod lineages.Herein we report on 87 specimens, 62 of them sufficiently preserved to permit specific identification, and all dating from the Lower Cretaceous (middle Albian).Eight new genera and nine new species are described and figured as Proterosceliopsis gen.nov., Proterosceliopsis masneri sp.nov., Bruescelio gen.nov., Bruescelio platycephalus sp.nov., Tithonoscelio gen.nov., Tithonoscelio resinalis sp.nov., Amissascelio gen.nov., Amissascelio temporarius sp.nov., Juxtascelio gen.nov., Juxtascelio interitus sp.nov., Alavascelio gen.nov., Alavascelio delvallei sp.nov., Electroteleiopsis gen.nov., Electroteleiopsis hebdomas sp.nov., Perimoscelio gen.nov., Perimoscelio tyrbastes sp.nov., and P. confector sp.nov.Morphological interspecific variability is low, hindering identification, and as such, taxa are principally diagnosed on structure of the female antenna, tibial spur formula, mesoscutal form, and head and metasomal anatomy.The taxa are discussed in relation to other fossil lineages of platygastroids as well as modern counterparts.All species belong to the "Scelionidae", a paraphyletic group relative to Platygastridae as currently circumscribed (including Platygastrinae, Scelioninae, Teleasinae, Telenominae).Platygastroid diversity will certainly rise in Spanish amber as abundant new material becomes available from the El Soplao and San Just outcrops.The name Jordanoscelio nom.nov. is proposed to replace the homonymous Microptera Kaddumi for a Jordanian amber (Early Cretaceous) genus of Scelionidae, resulting in Jordanoscelio attiki (Kaddumi) comb.nov.

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.
