Revision of the New World species of Stiphrosoma Czerny (Diptera: Anthomyzidae).
Bibliographic record
Abstract
Die neuweltlichen Arten der Gattung Stiphrosoma Czerny, 1928 werden revidiert. Vierzehn Arten werden festgestellt, darunter der Gattungstypus, S. sabulosum (Haliday, 1837), sowie 13 neue Arten: S. pectinatum sp. n. (Kanada: Ontario, Quebec; USA: District of Columbia, Georgia, Illinois, Indiana, Maryland, Massachusetts, Michigan, New York, North Carolina, Pennsylvania, Tennessee, Virginia, West Virginia), S. lucipetum sp. n. (Bahamas; Belize; Costa Rica; Kuba; USA: Florida), S. pullum sp. n. (Costa Rica), S. setipleurum sp. n. (Kanada: Neubraunschweig, Neuschottland, Ontario, Quebec; USA: Illinois, Indiana, Massachusetts, Michigan, New York, Pennsylvania, West Virginia), S. balteatum sp. n. (Kanada: Ontario, Quebec; USA: District of Columbia, Illinois, Massachusetts, Michigan, New York, Ohio, Tennessee, Wisconsin), S. hirtum sp. n. (Kanada: Alberta, Manitoba, Ontario, Saskatchewan; USA: Colorado, Minnesota, Montana, North Dakota, Utah), S. artum sp. n. (Kanada: Alberta, Saskatchewan; USA: North Dakota), S. helvum sp. n. (Kanada: Alberta; USA: Montana), S. stylatum sp. n. (Kanada: Manitoba, Ontario; USA: Minnesota, Utah), S. minor sp. n. (USA: Arizona), S. vittatum sp. n. (USA: Kalifornien), S. sororium sp. n. (Mexiko) und S. humerale sp. n. (Kanada: Alberta, Britisch Kolumbien, Manitoba, Neufundland, Neuschottland, Ontario, Quebec, Saskatchewan; USA: Michigan, New Hampshire, North Carolina, Tennessee, Vermont, Virginia, Washington; in der Paläarktis: - Lettland; Nord-Korea; Russland: Sibirien). Alle Arten werden beschrieben unter Abbildung der männlichen und weiblichen Genitalien sowie anderer diagnostischer Merkmale, und ihre Verwandtschaftsverhältnisse, Biologie und Verbreitung werden diskutiert. Das Vorkommen von S. sabulosum in der nearktischen Region wird erörtert aber ihre vermutete Einschleppung aus Europa ist unbewiesen. Die holarktische Verbreitung von S. humerale wird als natürlich erachtet; ostpaläarktische Populationen von S. humerale wurden früher irrtümlich für S. laetum (Meigen, 1830) gehalten. Flügelpolymorphismus wird von zwei neuen Arten beschrieben, S. hirtum sp. n. und S. artum sp. n., sowie von S. sabulosum. Eine neue Gattungsdiagnose für Stiphrosoma wird erstellt unter Berücksichtigung aller bekannten Arten, und die Verwandtschaftsverhältnisse der Gattung werden diskutiert. Ein Schlüssel für alle Arten von Stiphrosoma weltweit wird vorgestellt.StichwörterTaxonomy, Stiphrosoma, generic diagnosis, 13 new species, key, relationships, biology, distribution, wing polymorphism, New World.Nomenklatorische Handlungenartum Roháček & Barber, 2005 (Stiphrosoma), spec. n.balteatum Roháček & Barber, 2005 (Stiphrosoma), spec. n.helvum Roháček & Barber, 2005 (Stiphrosoma), spec. n.hirtum Roháček & Barber, 2005 (Stiphrosoma), spec. n.humerale Roháček & Barber, 2005 (Stiphrosoma), spec. n.lucipetum Roháček & Barber, 2005 (Stiphrosoma), spec. n.minor Roháček & Barber, 2005 (Stiphrosoma), spec. n.pectinatum Roháček & Barber, 2005 (Stiphrosoma), spec. n.pullum Roháček & Barber, 2005 (Stiphrosoma), spec. n.setipleurum Roháček & Barber, 2005 (Stiphrosoma), spec. n.sororium Roháček & Barber, 2005 (Stiphrosoma), spec. n.stylatum Roháček & Barber, 2005 (Stiphrosoma), spec. n.vittatum Roháček & Barber, 2005 (Stiphrosoma), spec. n.

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.
