Lapied leg.; BOLD Sample ID: EW-MI15-0079; MNHN. ETYMOLOGY. — This species is named in acknowledgment to Julien Touroult, co-organisator of the “Our Planet Reviewed” in the Mitaraka Massif. ECOLOGY. — The three specimens of O. touroulti Decaëns & Bartz, n. sp. were found in decaying trunks and termite nest in a lowland, a slope and a plateau forest (Fig. 19C, D). DISTRIBUTION. — Omodeoscolex touroulti Decaëns & Bartz, n. sp. is only known from the Mitaraka Massif. DESCRIPTION External morphology (Fig. 19A, B) Body shape cylindrical, slightly flattened posteriously. Body pigmentation dorsally reddish-brown, ventrally light yellow-brown. Body length: 25 mm in the holotype, 18 mm one paratype, after ethanol fixation.Body mass: 0.04 g after ethanol fixation in the holotype, 0.015 g in the paratype. Diameter: 1.2 to 1.5 mm in the preclitellar region, 1.3 to 1.6 mm in the clitellum, 1.2 to 1.5 mm in the postclitellar region. Number of segments: 92 in the holotype, 86 in the paratype. Prostomium tanylobic. Dorsal pores begining in 4/5. Setae closely paired, beginning in II, ab ventral and cd sub-ventral. Setal arrangement aa:ab:bc:cd = 4:1:4:1, dd> ½ Ø. Clitellum in XIII-XX, annular. Genital markings in two transversal lips in XVII and XX, delimiting a rectangular acanthodriline male field.One pair of ventral male pores in XVIII, and ovipores one pair in XIV. Spermathecal pores not visible. Nephridial pores not visible. Internal anatomy Septa: membranous. Gizzard: absent. Calciferous glands: two pairs in XIV and XV, with lamellar structure, kidney shape and attached through the middle inside part. Esophagus-intestine transition in XVI. Typhlosole weak. Hearts: five pairs, last three intestinal bigger and last pair in XII. Excretory apparatus holoic. Prostatic glands: two pairs in XVII and XIX, spatula-shaped. Ovaries: one pair in XIII, grape-shaped. Testes: two pairs of testes sacs in X and XI. Seminal vesicles: two pairs in XI and XII, very small and weak. Spermathecae: three unpaired midventral in VI to VIII, spherical. REMARKS O. touroulti Decaëns & Bartz, n. sp. is different from the two previously described species of Omodeoscolex by the presence of unpaired instead of paired spermathecae. Despite this strong difference, we provisionally assign the species to the genus Omodeoscolex because of lack of a gizzard and of the holonepridial type of its excretory system. This species corresponds to OTU#012 in Maggia et al. (2021).

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.
