A worldwide review of the genus Arganthomyza Roháček, with revision of the Nearctic species (Diptera: Anthomyzidae)
Bibliographic record
Abstract
World representatives of the genus Arganthomyza Roháček, 2009 (Diptera, Anthomyzidae) are reviewed, keyed and their relationships are discussed on the basis of a phylogenetic analysis of morphological characters. The Nearctic species of Arganthomyza are revised, described and illustrated, and first data about their biology and distribution are given. Five new species, A. carbo sp. n. (Canada, USA), A. acuticuspis sp. n. (USA), A. bivittata sp. n. (Canada, USA), A. duplex sp. n. (Canada, USA) and A. disjuncta sp. n. (Canada, USA) are described and A. socculata (Zetterstedt, 1847) is newly recorded from the Nearctic Region (USA: Alaska). Based on the phylogenetic analysis, four main clades/species groups are recognized within Arganthomyza, represented by the following species: A. barbarista Roháček, 2009 (A. barbarista group); A. setiplanta (Roháček, 1987), A. versitheca Roháček, 2009 and A. carbo sp. n. (A. setiplanta group); A. acuticuspis sp. n., A. bivittata sp. n. and A. duplex sp. n. (A. duplex group); A. disjuncta sp. n. and A. socculata (Zetterstedt) (A. socculata group). Considering the contemporary distribution and relationships of Arganthomyza species, it is hypothesized that the A. barbarista group and A. setiplanta group originated in East Asia while the A. duplex group and the A. socculata group each has its origin in the Nearctic Region.

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.
