Abstract
† Palaeoleptochromus O'Keefe Palaeoleptochromus O'Keefe, 1997: 380 (in O’Keefe et al. (1997)). Type species: Palaeoleptochromus schaufussi O'Keefe, 1997 (orig. des.). Palaeoleptochromus, with its sole species P. schaufussi (Fig. 86) from the Upper Cretaceous Canadian amber, differs from Clidicus in a pair of long setae on the posterior margin of vertex and the labial palps: the palpomere II is pedunculate and strongly broadened in its distal half, where it is about 4 times as broad as at base, and palpomere III is bristle-like, extremely slender and pointed. Other characters included in the original description seem to agree with those of Clidicus, except that P. schaufussi is very small, only 2.23 mm long (although the smallest Clidicus is 2.99 mm long). The type specimen was not available for my study, but it seems that most characters crucial to place P. schaufussi in a taxonomic context are not observable in the inclusion. In the recently published phylogenetic analysis Palaeoleptochromus was placed within Clidicus, and these names may be synonymous, but the evidence for this is too scarce to make such a decision. The placement of Palaeoleptochromus remains unclear.

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.
