The Mealy Plum Aphid and Its Congeners: A Synonymic Revision of the Prunus-Infesting Aphid Genus Hyalopterus (Hemiptera: Aphididae)
Bibliographic record
Abstract
The three species of Hyalopterus Koch cause economic damage to various stone fruit trees of the genus Prunus L., H. pruni (Geoffroy), H. amygdali (Blanchard), and H. persikonus Miller et al. Although the third species was established recently, it has been suggested that one of the twelve older synonyms of the first two may be applicable to the third. We undertook a synonymic revision of the nominal species of Hyalopterus to clarify the taxonomy and nomenclature of the genus. The three valid species of Hyalopterus are affirmed to be H. pruni (the mealy plum aphid), H. amygdali, and H. arundiniformis Ghulamullah, stat. nov. We determined that H. mimulus Börner and H. persikonus are junior synonyms of H. arundiniformis, syn. nov., and that Brachysiphum kobachidzei Rusanova is not a synonym of H. amygdali but a valid species of Aphis, stat. nov., comb. nov. Aphis amygdalipersicae Mosley is likely a senior synonym of Brachycaudus helichrysi (Kaltenbach), syn. nov.; to maintain current usage, we establish the former as a nomen oblitum with respect to the latter. Finally, several other nominal species were unevaluable and are therefore listed as nomina dubia.

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.
