Abstract

fetched live from OpenAlex

Among nine Harpellales (Trichomycetes) reported from aquatic insect larvae collected in Newfoundland, Canada, four new species are described: Harpellomyces abruptus [living in Thaumalea verralli (Diptera: Thaumaleidae)], Orphella avalonensis [in Leuctra ferruginea (Plecoptera: Leuctridae)], Stachylina litoralis [in Telmatogeton japonicus (Diptera: Chironomidae)], and an unnamed species of Smittium (in Chironomidae) from which an axenic culture was obtained. Other Harpellales were from Simuliidae (Harpella melusinae, Pennella simulii, Simuliomyces microsporus), Chironomidae (Stachylina robusta), and an unnamed new genus in caddis fly larvae (Trichoptera). Low vagility of Plecoptera and the occurrence of different species of Orphella in the USA and Europe suggest that the genus existed before the North Atlantic formed a barrier as the continents separated. It is hypothesized that vicariant speciation may have occurred in Orphella as well as in Harpellomyces from Thaumaleidae larvae.

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.

Not 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.
