Right antenna and terminalia placed in a microvial with glycerin, both pinned along the specimen. Etymology. From the Latin folium (= leaf), the specific epithet refers to the shape of the ejaculatory ducts of phallus in the male genitalia. Geographical distribution. Colombia (Boyacá, Cundinamarca, Valle del Cauca, Nariño) (Fig. 108). Habitat. The specimens were collected at the Santuario de Fauna y Flora Iguaque reserve, where the vegetation is composed of forests of the cordillera of the Northeast region; Parque Nacional Natural Chingaza with ‘frailejón’ vegetation of the Andean region; Parque Nacional Natural Farallones de Cali, where the vegetation is composed of forests of the mountain range of the Southwest region and in the Reserva Natural La Planada, where the vegetation is composed of cloudy forest of the Southwest region of Colombia. Taxonomic notes. Based on males and due to the shape of the surstyli, S. folium sp. nov. is similar in appearance to S. paganus (Hardy) [see figure 31 presented by Rafael (1990)]. It differs from S. paganus by having the apex of phallic guide short, with acute tip and translucent lobe laterally (Fig. 89) [versus apex of phallic guide thickened, with truncated tip and two rigid lobes apically, figure 33 presented by Rafael (1990)]; phallus with leaf-shaped membranous projections laterally and dorsally (Fig. 89) [versus phallus with membranous projections rounded laterally, figure 33 presented by Rafael (1990)]; ejaculatory apodeme needle-shaped, with margins somewhat straight (Fig. 90) [versus ejaculatory apodeme mushroom-shaped, figure 34 presented by Rafael (1990)].

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.
