Abstract
In this study, we test and corroborate the phylogenetic position of Heterosyphus within Helictopleurus using mitogenomes and nuclear loci. Our recent samplings revealed that males of the former Heterosyphus sicardi Paulian, 1975 (today under Helictopleurus d’Orbigny, 1915) have extraordinary bilateral clypeal horns which are exclusive within the genus. We provide a taxonomic review of the fungicola species group of Helictopleurus and discuss the systematic position of H. sicardi within the group. The male phenotype of H. sicardi is described and photographs of the body and genitalia of the members of the fungicola group are given, as well as a diagnostic key to species of the group. Helictopleurus fungicola peyrierasi is considered to be a distinct species within the genus ( H. peyrierasi stat. rest. ). Helictopleurus pluristriatus d’Orbigny, 1915 syn. nov. is established as a junior synonym of H. fungicola (Fairmaire, 1899).

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
