Abstract
The study is based on two Baltic amber inclusions from the middle Eocene, studied by means of micro-computed tomography (micro-CT). Inner male genitalic features are partly visualised and the specimens described as Metanephrocerus groehni Kehlmaier & Skevington sp.n. and Metanephrocerus hoffeinsorum Kehlmaier & Skevington sp.n. Based on a phenetic comparison of the basic morphological composition of male terminalia on a subfamily level, Metanephrocerus Aczél, 1948 and Protonephrocerus Collin, 1931 are excluded from Nephrocerinae and placed into the new subfamily Protonephrocerinae Aczél, 1948 stat.n. An identification key to the named morphospecies of Metanephrocerus is provided.

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
