Holocentropus varangensis , Mey 1987
Bibliographic record
Abstract
Holocentropus varangensis Mey, 1987 NORWAY, FI, Sør-Varanger: Varanger Peninsula, lake inlet at tributary 3 of Gjøkvatn, 10 July 1969, 1♂ (holotype), leg. W. Tobias (the genitalia of the holotype are shown in Figure 3A– C). Notes: The holotype is housed in the Senckenberg Museum of Natural History, Görlitz, Germany - not in the Museum of Natural History, Berlin, as stated in Mey (1987). The specimen was originally labelled “ H. insignis ” by Wolfgang Tobias. The abdomen including the genitalia was already cleared in KOH by Mey. The holotype was made available for our study by the Senckenberg Museum of Natural History, Görlitz. DNA sequencing With permission from Senckenberg Museum, we attempted to obtain a DNA barcode from one leg of the holotype of H. varangensis. The leg was processed non-destructively, i.e. securing conservation of the exoskeleton. The aim was to obtain a barcode sequence of the mitochondrial cytochrome oxidase subunit I gene (COI) to be compared with similar available sequences for H. insignis and H. picicornis (see Boonstra et al. 2018). As the mitochondrial DNA is maternally inherited, the barcode of H. varangensis - if this is a hybrid - should be identical to that of one the potential mothers, either H. insignis or H. picicornis. This would strongly support the hybridization hypothesis. The extraction was carried out by courtesy of the Ecology and Genetics Research Unit, Oulu. The sample was then analyzed (28 April 2022) at the Canadian Centre for DNA Barcoding (CCDB) (Plate: CCDB-40752; Process-id: LEFIJ28025-22). It was then subjected to the “ NGSFT ” protocol as explained in Prosser et al. (2016).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
