Taxonomy of Myxobolus ridouti N. Sp. and M. ridgwayi N. Sp. (Myxozoa) from Pimephales notatus and Semotilus atromaculatus (Cypriniformes) in Ontario
Bibliographic record
Abstract
Myxobolus ridouti n. sp. and M. ridgwayi n. sp. are described, respectively, from Pimephales notatus (Rafinesque) and Semotilus atromaculatus (Mitchill) in Algonquin Park, Ontario, Canada. Both are intracellular in striated muscles of the body flank. Spores of M. ridouti n. sp. are subcircular (9.5-10.5 μm long by 9.4-10.9 μm wide); those of M. ridgwayi n. sp. are oval (10.0-12.1 μm long by 9.5-10.5 μm). Both species have spores with a small, distinct swelling (1 μm) on the spore valve near the posterior sutural ridge, similar to that described for Myxobolus insignis Eiras, Malta, Varella, and Pavanelli, 2005. It looks to be non-nuclear in origin, apparently part of the internal face of a spore valve, and could be taxonomically useful. Partial sequence data of the 18S rDNA from both species are unique among those species in the genus that have been sequenced. The sequences have the greatest overall identity with various species of Myxobolus from cyprinids in North America, Europe, and Asia, with a constructed molecular phylogeny having the 2 new species forming a separate clade.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
