Revision of the endemic New Zealand braconid wasp genus <i>Metaspathius</i>: new subfamily placement, and descriptions of four new species including three with fully winged females (Hymenoptera: Braconidae: Mesostoinae)
Bibliographic record
Abstract
The endemic New Zealand cyclostome braconid wasp genus Metaspathius Brues, which was previously only known from a single specimen, an apterous female, is revised. Four new species, including three with fully winged females, are described and illustrated: Metaspathius chathamicus Ward, sp. nov.; M. hemipterus Belokobylskij, sp. nov.; M. kuscheli Ward & Belokobylskij, sp. nov.; and M. sharkeyi Quicke & Butcher, sp. nov. Metaspathius apterus Brues is illustrated. The first host record for the genus is provided: Metaspathius kuscheli sp. nov. is recorded as a larval parasitoid of the New Zealand endemic weevil Phrynixus astutus Pascoe, 1876 (Curculionidae). DNA sequence data (CO1 and 28S) for two of the species are included in an analysis of a broad range of cyclostome Braconidae with emphasis on basal taxa. The results show that Metaspathius belongs to a clade restricted to New Zealand within the heterogeneous basal subfamily Mesostoinae van Achterberg, 1975. A revised morphological diagnosis of the Mesostoinae is presented in the light of the discovery that Metaspathius is a member. The relationships of the Maxfischeriinae are discussed in the light of molecular findings.http://www.zoobank.org/urn:lsid:zoobank.org:pub:512AD512-5F2A-44C8-9951-AD739995C10C

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.
