Cerophytum lii Qiu & Ruan, sp. nov. (Coleoptera: Cerophytidae): First Record of the Family in China with Study on Its Thoracic Functional Morphology Through 3D Reconstruction
Bibliographic record
Abstract
The beetle family Cerophytidae is reported from China for the first time, based on the discovery of Cerophytum lii Qiu & Ruan, sp. nov. and Cerophytum sp., both from Daweishan Mountain in Southeast Yunnan Province. Detailed descriptions and diagnostic illustrations of Cerophytum liisp. nov. are provided, along with an identification key to extant Cerophytum species worldwide. A representative specimen of the new species (a male paratype) underwent micro-computed tomography scanning, enabling three-dimensional reconstruction and virtual dissection of its thoracic morphology. Internal muscular architecture and exoskeletal structures of its thorax are illustrated and described. Comparative morphological analyses revealed convergent evolution in the clicking structures of Cerophytum lii sp. nov. and Campsosternus auratus (Drury), with the latter exhibiting more specialized structural modifications that enhance its jumping performance to a greater degree. In contrast, Cerophytum liisp. nov. exhibits morphological adaptations primarily suited for rapid walking and flight.

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.
