Description of Xiphinema pupureum n. sp. (Nematoda: Longidoridae), a new Xiphinema americanum group species detected from the rhizosphere of Ilex purpurea from Japan
Bibliographic record
Abstract
Summary A new species of Xiphinema americanum group was recovered in the rhizosphere of holly (Ilex purpurea) imported from Japan. It is described and illustrated in the present study as X. purpureum n. sp. The new species is characterised by moderately long females 2267 (2115-2550) μm, round lip region slightly offset from the rest of the body, 103.5 (98.5-109.0) μm long odontostyle, genital branches without discernible endosymbiotic bacteria, vulva located at 54.1 (51.6-57.1)% of the body, tail 30 (24.3-33.4) μm long with a broadly rounded terminus, male absent and four juvenile developmental stages. The polytomous codes of the new species are as follows: A4/5, B2/3, C1/2, D2/3, E3, F1, G1, H2, I1/2/3. The new species was molecularly characterised using near full length 18S, ITS1, and 28S D2-D3 regions of rRNA, and mitochondrial cytochrome c oxidase subunit I gene sequences. The phylogenetic analyses placed X. purpureum n. sp. with X. americanum group species, particularly with X. brevicolle complex species. This is the third X. americanum group species described from Japan.
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.
