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.

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.
