Prochyliza nigricoxa Melander & Spuler 1917
Bibliographic record
Abstract
Prochyliza nigricoxa (Melander & Spuler, 1917) Piophila nigricoxa Melander & Spuler 1917: 64. Type locality: USA (Washington). Lectotype (♂) designated by Steyskal (1968) and paralectotypes (4 ♂ and 5 ♀) designated by Ozerov (2003) in Smithsonian National Museum of Natural History. Material examined. 1 ♂ (CNC): Canada, Alberta, Sulfur Mountain; 28.vii.1967; leg. J. R. Vockeroth; det. J. F. McAlpine. 1 ♀ (CNC): Canada, Alberta, Cameron Lake; 17.vi.1956; leg. E. E. Sterns. Diagnosis. The following combination of characters is distinctive of P. nigricoxa: lower two- to three quarters of the frons orange; gena orange; front coxa darkened (Fig. 5 A); mid and hind tibiae entirely yellow; mid tibia and hind coxa of males not ornamented. Male sternites 5 to 8 as in Fig. 2 G. Remarks. The species identity was confirmed by Steyskal (1968) and Ozerov (2003), after studying the type specimens. Biology. The larvae are necrophagous. Feeding larvae have been collected on the bone marrow of a human femur, and reared under laboratory conditions on chicken wings, oxtails, beef liver and cheese (Skinner et al., 1988). Distribution. Nearctic; originally recorded from Washington, Idaho and Montana, USA (Melander & Spuler 1917), it is widely distributed throughout North America (McAlpine 1977).
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.
