Abstract
The genus Neidiopsis is small comprising eight known taxa distributed in oligotrophic to dystrophic freshwater habitats. During observations of diatoms from alpine intermittent ponds on the Shara Mountain, Republic of North Macedonia, a species of Neidiopsis with high abundance was observed. It is characterized by linear to linear–lanceolate valves with a slightly undulated margin, 25.0–43.5 μm long and 6.0–7.0 μm wide. The raphe is filiform with straight proximal and deflected distal raphe endings to the same side of the valve. Striae are partly biseriate near the axial area and continue as uniseriate circular areolae (ca 40 in 10 μm) towards the valve mantle. Striae on each side of the valve are crossed by a prominent longitudinal line located slightly closer to the valve margin. Ultrastructural features of the type population clearly place this taxon into the genus Neidiopsis and aligned to N. levanderi sensu stricto. A similar documented ecotype population (N. levanderi “calcicola”) sensu Lange-Bertalot (2001) is combined with our population and considered a new species N. borealis sp. nov.

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 it
