Abstract
Canthon machadoi (Martínez & Pereira, 1967) comb. nov. Fig. 46 B–C Glaphyrocanthon machadoi Martínez & Pereira, 1967: 53–55 Glaphyrocanthon machadoi – Halffter & Martínez 1977: 63. Sylvicanthon machadoi – Halffter & Martínez 1977: 63. — Vaz-de-Mello 2000: 195. — Silva et al. 2007: 230. — Costa et al. 2009: 91. Canthon machadoi – Krajcik 2012: 64. Etymology The specific name refers to the Brazilian odonatologist Ângelo B.M. Machado, collector of the type series (Martínez & Pereira 1967). Pinto (2016) presented an interesting short biography of Ângelo Machado. Material examined Paratypes (4 ♂♂, 1 ♀) BRAZIL: 1 ♂ (“ Glaphyrocanthon / machadoi sp. n / Martinez - / P.

Machado ”, “ Glaphyrocanthon / machadoi sp. n / Martinez - / P. Pereira det. 60 ”, “♂”, “PARATIPO”) (MZSP). Collecting sites BRAZIL. Pernambuco: Reserva Biológica de Serra Negra. Comments The eight specimens of the type series of C. machadoi are the only known individuals of this species, which is apparently endemic to a ‘ brejo de altitude ’ (Caatinga moist-forest enclave) in the Brazilian state of Pernambuco. However, only five of those specimens were found during this work: three male paratypes housed at the MZSP, and a male and a female paratype at the CMNC. Martínez & Pereira (1967) mentioned the holotype male and allotype female of C. machadoi were deposited at the “author’s collection”, without specifying which of the authors. As said earlier in this work, Martínez’s holotypes and allotypes are nowadays housed at the MACN, while paratypes and ordinary specimens were incorporated to the CMNC via the Henry and Anne Howden collection. In none of them, however, either the holotype or the allotype of C. machadoi is preserved. Therefore, the whereabouts of those two specimens is unknown to us. As for the fifth male paratype, Martínez & Pereira (1967) stated it was deposited in the personal collection of its collector, Ângelo Machado (Belo Horizonte, Minas Gerais, Brazil), and it is probably still housed there.

How this classification was reachedexpand
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.
