Taxonomy and ecology of the Arctic oribatid mite Svalbardia lucens comb. nov. (Acari, Oribatida, Ceratozetidae): resolving a long-standing confusion
Bibliographic record
Abstract
For decades, two very similar Arctic oribatid mite species in the family Ceratozetidae—Oromurcia lucens (L. Koch, 1879) and Svalbardia paludicola Thor, 1930—were considered independent taxa and were often confused in the literature. Based on morphological analysis of specimens from the type localities, as well as extensive material from different Arctic regions, we make the following taxonomic proposals: Svalbardia lucens (L. Koch, 1879) comb. nov. (=Svalbardia paludicola Thor, 1930 syn. nov.). Furthermore, we propose that the subfossil Svalbardia rostralis Druk, 1982 (in Kiselev et al. 1982) is a junior subjective synonym (syn. nov.) of S. lucens. We summarize data on distribution and habitat preferences of S. lucens in the Arctic. The frequent occurrence of S. lucens in Pleistocene deposits and its strong dependence on moisture make this species a reliable “type fossil” in paleoclimatic reconstructions.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
