The cave-dwelling dipluran (Diplura, Campodeidae) on the edge of the Last Glacial Maximum in Vancouver Island caves, North America (Canada)
Bibliographic record
Abstract
A new cave-dwelling dipluran of the North American endemic genus Haplocampa is described, coming from a couple of caves excavated in a small limestone karstic area near Port Alberni, Vancouver Island (British Columbia, Canada). To Haplocampa belong five soil-dwelling species. L. M. Ferguson cited no less than eight more species living in soil and cave habitats in several US states but without producing any formal descriptions. Haplocampa, in spite of its large lateral crests on the unequal claws, has clear taxonomical features as a Campodeinae and is closely related with the cave-dwelling Pacificampa and Eumesocampa genera, due to sharing similar macrosetae body distribution and absence or reduction of the lateral process. The new proposed species, Haplocampawagnelli Sendra, sp. n., is rather interesting for its troglomorphic features: antennae with 32 antennomeres; olfactory chemoreceptors, each a multiperforated, folded-spiral structure; and numerous gouge sensilla. In addition, it is one of the northernmost troglomorphic species to have colonised – presumably recently – an area occupied by the Late Wisconsinian North America ice sheet during the Last Glacial Maximum. Furthermore, the close affinities between Haplocampa, Pacificampa (from caves in the extreme east of continental Asia and the southern Japanese Islands), Metriocampa (from the east of Asia and North America) and Eumesocampa (endemic to North America) suggest probable dispersal events over the Bering Land Bridge.

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.
