Abstract

fetched live from OpenAlex

Two species of the genus Cladotanytarsus Kieffer, 1921 are described as adult males, both peculiar in having distinctively elongated hypopygial anal points. The male of Cladotanytarsus bilyji Giłka et Puchalski, sp. nov. (Canada, Manitoba; USA, Ohio) is presumed to be a close relative of C. nigrovittatus (Goetghebuer, 1922). Another unknown Cladotanytarsus species (USA, Illinois and Louisiana) keys with the European C. donmcbeani Langton et McBean, 2010. The intraspecific variability of the male C. acornutus Jacobsen et Bilyj, 2007 is also presented on the basis of new records (Canada, Ontario; USA, South Carolina). Cladotanytarsus males with similarly structured elongate anal points are reviewed, including C. tobaquardecimus Kikuchi et Sasa, 1990, considered a junior synonym (syn. nov.) of C. conversus (Johannsen, 1932). As a compilation of this study, a key to the identification of the adult males of 14 Cladotanytarsus species is provided.

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.
