Abstract
Abstract Two new genera and eight new species of featherwing beetles (Coleoptera: Ptiliidae) possessing a remarkable horizontal perforation of the mesoventral keel are described: Skidmorella vietnamensis sp.n. (Vietnam), S. memorabilis sp.n. (Indonesia), S. serrata sp.n. (Vietnam), Fenestellidium capensis gen. et sp.n. (South Africa, type species), F. kakamegaensis sp.n. (Kenya), Cissidium okuensis sp.n. (Cameroon), Dacrysoma usambarensis gen. et sp.n. (Tanzania, type species) and D. felis sp.n. (Madagascar). A phylogenetic analysis of 24 taxa and 37 parsimony‐informative characters supports the hypothesis of a single origin of the mesoventral perforation, thus uniting Discheramocephalus , Skidmorella , Africoptilium , Fenestellidium , Cissidium and Dacrysoma into a pantropically distributed clade, for which a new tribe Discheramocephalini (type genus Discheramocephalus ) is proposed. Identification keys to Discheramocephalini genera and, in some cases, to species are provided. Each new species is illustrated with scanning electron microscopy images.

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
