Abstract
Using an integrative approach considering nuclear and mitochondrial molecular phylogeny, shell morphology, expressed ecological niches and biogeography, we revise the taxonomy and nomenclature within the Holarctic land snail genus Perpolita (Gastrodontidae; Gastropoda). All supported taxa were found to be not only genetically distinct but also to possess diagnostic conchology, especially in terms of colour and the strength of microsculptural spiral grooves (‘sillons’) cut into the bottom shell surface. Our revision resulted in: (i) synonymization of Perpolita suzannae into P. dalliana; (ii) erection of Lapa gen. nov. to encompass species limited to tropical/subtropical habitats in the Caribbean basin; (iii) elevation of Perpolita radiatella to a full species, ranging from Continental Europe to the Yukon. It had previously been confused with both P. electrina and P. hammonis; (iv) erection of Perpolita radiatella hesperia subsp. nov. to designate a distinct genetic race ranging from the Altai Mountains to central Europe. http://zoobank.org/urn:lsid:zoobank.org:pub:3FFD4B50-1CD2-4C1C-A27C-F20C9EA7534C

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
