New species of Haematoloechus (Digenea: Plagiorchidae) in the lung of the foothill yellow-legged frog Rana boylii (Anura), from Humboldt County, California, USA
Bibliographic record
Abstract
A new species of Haematoloechus is described from the lungs of Rana boylii from Humboldt County,California. The new species is similar to Haematoloechus buttensis, Haematoloechus kernensis, and Haematoloechuscomplexus in general course of the uterus and gonad shape. It is similar to H. buttensis by having a cirrus sac terminatingmidway between the posterior margin of the pharynx and the anterior margin of the ovary, and having a smaller oral/ventral sucker ratio; to H. complexus by having the genital pore ventral to the pharynx, and it is similar to H. kernensisby having a larger oral sucker to pharynx width ratio. The new species is unique by lacking an extra-cecal longitudinaluterine loop from the hind-body. Molecularly, the new species differs 1.04–1.15% in partial 28S sequence with respectto H. complexus, and a monophyletic grouping of these specimens in a phylogenetic analysis of all available sequencedata consistent with the species-specific status proposed herein. Evidence is also presented to suggest that specimensidentified as H. buttensis in Rana pretiosa from British Columbia, Canada represents a new, but still undescribed species.The importance of conducting biological inventories of helminths, along with continued monitoring of populations, andcollections based taxonomy are related.

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.
