Abstract
Sclerocoelus subbrevipennis (Frey, 1954) Limosina subbrevipennis Frey, 1954: 35. Leptocera (Limosina) subbrevipennis – Richards 1980: 620. Sclerocoelus subbrevipennis – Marshall 1997: 104. Diagnosis Body length 2.2 mm. Membrane around prosternum bare. Male S5 rectangular, posteromedially pale, bilobed, and covered in short, flattened setulae (cf. Marshall 1997: figs 54, 56); perianal pads well developed and dark; surstylus subtriangular with a rectangular anteroventral lobe bearing a posteroventral patch of thickened setae (cf. Marshall 1997: figs 52–53); postgonite very narrow and strongly sinuate (cf. Marshall 1997: fig. 55). Female S8 hourglass-shaped, lateral margins curved outwards into two prominent ridges (cf. Marshall 1997: fig. 59). Material examined TRISTAN DA CUNHA – Inaccessible Island • 1 ♂; SW of Denstone Hill; 37°02′ S, 12°12′ W; 14 Oct. 1989; H.M. Barber leg.; albatross nest; DEBU. Distribution South Atlantic: Tristan de Cunha (Inaccessible Island, Nightingale Island) Remarks Sclerocoelus subbrevipennis (Frey) is the only unequivocal Sclerocoelus species with a distribution outside the New World, and one of only four species found outside the Neotropical region. The close relationship between S. subbrevipennis and Neotropical members of the S. galapagensis group was documented by Marshall (1997) and we are confident that the species is correctly placed. Although undoubtedly a Sclerocoelus, it is clearly distinct from all other species we have examined so there is no evidence that it is secondarily introduced to Tristan da Cunha. Some of the type specimens were collected in bird nests and in rotting vegetation.

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.
