Abstract
Abstract. The acalypterate family Inbiomyiidae fam.n. (Diptera, Carnoidea) is described for the newly discovered Neotropical genus Inbiomyia gen.n. with its type species I . mcalpineorum sp.n. from Costa Rica. The genus ranges from Guatemala south to French Guiana and Bolivia and includes a total of fourteen undescribed species, ten of which will be described formally in a separate paper. Inbiomyia is distinctive, with characteristic, extremely shortened head with nonfunctional ptilinum and reduced chaetotaxy, shortened first flagellomere with very elongate, dorsoapically inserted arista, proboscis with largely separate labellar lobes that point in different directions, mid tibia lacking apicoventral bristle, unusual fusion of male sternites 5–7, reduced male sternite 8, elongate surstyluslike ventral epandrial lobes, cerci absent in both sexes, extremely truncate female genitalia, and large, extremely flattened eggs. The larva of Inbiomyia and its biology are unknown. Inbiomyia occurs mostly in primary lowland rain forest and often is associated with the decaying foliage of fallen trees. Inbiomyiidae belong in the superfamily Carnoidea. The previously doubtful monophyly of the Carnoidea is accepted tentatively on the basis of newly established synapomorphies of the male genitalia. Family level relationships of the Carnoidea are analysed quantitatively for the first time based on a matrix of fifty‐eight morphological characters. The putative sister group relationship of Inbiomyiidae to the monotypic Australasian family Australimyzidae is supported by several synapomorphies, mostly from the male and female postabdomen. Family status for the Australimyzidae is confirmed, rejecting previous claims of a sister group relationship (or synonymy) with the Carnidae. The analysis also leads to revised hypotheses of the relationships of Cryptochetidae and Acartophthalmidae, and the paraphyly of ‘Tethinidae’ with regard to Canacidae, suspected by previous authors, is confirmed.

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 it
