Dryophthorinae weevils (Coleoptera: Curculionidae) of the forest floor in Southeast Asia: DNA analysis of two new Nephius from Vietnam and Taiwan suggests non-monophyly of Stromboscerini
Bibliographic record
Abstract
The weevil genus Nephius Pascoe is for the first time reported from Vietnam (N. argus sp. nov.) and Taiwan (N. acastus sp. nov.). Until now the genus was attributed to the tribe Stromboscerini and contained nine nominal species and two subspecies known only from the type series. Phylogenetic analysis of one mitochondrial (COI) and two nuclear (ITS2 and 28S) markers strongly rejected monophyly of the tribe by placing the monophyletic Nephius as sister to a clade consisting of reciprocally monophyletic Dryophthorus and the rest of Stromboscerini. All herein used data (localities, DNA sequences, specimen images) are available online in public datasets dx.doi.org/10.5883/DS-NEPHIUS1 and dx.doi.org/10.5883/DS-NEPHIUS2.
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.
