Phylogenetic Evolution of Coccoidea and Systematics of the Family Diaspididae
Bibliographic record
Abstract
This study analyzes the phylogenetic evolution of scale insects (Hemiptera: Coccoidea) and the systematic development of the family Diaspididae based on paleontological, morphological, and taxonomic data. Fossil specimens from Baltic and Canadian amber, as well as materials from the Eocene and Oligocene, were examined using published sources. The results show that early scale insects emerged as an independent group in the Permian, with the main families forming during the Carboniferous, Permian, and Triassic, while most modern groups originated in the Cretaceous. The family Diaspididae represents the most specialized lineage within Neococcoidea, characterized by reduction in body size, regression of morphological organs, and development of a wax covering. The findings highlight the significance of evolutionary processes in shaping the taxonomy and global distribution of Diaspididae.

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.
