Eudontomyzon graecus, a new nonparasitic lamprey species from Greece (Petromyzontiformes: Petromyzontidae)
Bibliographic record
Abstract
Eudontomyzon graecus, sp. n., a nonparasitic lamprey from Greece, is restricted to the Loúros River drainage, Ionian Sea basin, Epirus Periphery. It is distinguished from Eudontomyzon hellenicus, the other nonparasitic Greek brook lamprey, occurring allopatrically in the Strymon River drainage, Aegean Sea basin, Central Macedonia Periphery, by possessing at the adult stage a relatively longer tail and a greater number of bicuspid teeth in both the first row of anterials and posterials, and at the ammocoete stage, by a relatively shorter trunk and longer tail and a less pigmented upper lip, tongue precursor bulb and lateral aspects of the elastic ridge. Taken individually, these three adult and five larval characters, varied in their diagnostic power from 71 to 88% for the adults and from 91 to 97% for the ammocoetes. However, in combination, these characters provide sufficient evidence to justify recognition of this new species, in addition to the wide distance (ca 400 km) separating it from its closest extant relative, as well as its independent origin.

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; both teacher heads agree on what is shown here.
