A taxonomic revision of the Paranoplocephala primordialis (Douthitt) complex (Cestoda: Anoplocephalidae) in voles and squirrels
Bibliographic record
Abstract
This study redescribes Paranoplocephala primordialis (Douthitt) in the red squirrel, Tamiasciurus hudsonicus, describes two new, related species of Paranoplocephala Lühe from Microtus and Myodes (syn. Clethrionomys) voles, and summarizes the patterns of their host specificity and geographic distribution, particularly in Alaska and adjacent regions in Canada and north-eastern Siberia. Paranoplocephala nearctica n. sp. and Paranoplocephala alaskensis n. sp. are shown to be slightly, but consistently differentiated host-specific parasites of Myodes rutilus and Myodes gapperi, and Microtus miurus, respectively. The related Paranoplocephala sp. from Microtus oeconomus is also suspected to be specifically distinct, but the available material does not allow a description of a new species.Paranoplocephala primordialis-like cestodes occur widely in rodents in North America, ranging from California to Labrador and Alaska, but also in north-eastern Siberia. The specific identity of the few Eurasian specimens could not, however, be confirmed. Paranoplocephala primordialis-like species seem to be rare in all host species and regions, maximum prevalences being 8%, 3%, 6.5% and 5% for P. primordialis, P. nearctica n. sp., P. alaskensis n. sp. and Paranoplocephala sp., respectively.

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.
