Bibliographic record
Abstract
Truttaedacnitis clitellarius (Ward & Magath, 1917) Petter, 1974 Synonym: Cucullanus clitellarius Ward & Magath, 1917 Description (after Choudhury & Dick 1996a). With characteristics of the genus. Body moderately robust, cephalic end rounded, cuticle with transverse striations. Posterior part of body often curved ventrally. Narrow lateral alae beginning in cervical region, terminating at anal region. Mouth opening spindle-shaped, with three conspicuous papillae on either side—the central one likely an amphid. Mouth opening bordered by transparent cuticular collarette bearing weak longitudinal rib-like structures (“teeth”). Inner circle of three small papillae present. Two bud-shaped deirids, one on either side, often asymmetrical, adjacent to lateral alae, and posterior to nerve ring. Tail conical, gently tapering, bearing mucron. Hemizonid posterior to nerve ring. Oesophagus muscular, clavate, expanded anteriorly to form pseudobuccal capsule. Bilaterally symmetrical cephalic plates present, separated by narrow sutures and attached to thickened cuticular plates of pseudobuccal capsule (Fig. 86 C). Oesophageal lumen lined by cuticle, each side of triradiate lumen thickened to give appearance of “longitudinal rods” embedded into oesophageal musculature. Oesophago-intestinal junction guarded by cuticular folded valve. Excretory pore at about mid-level of pseudobuccal capsule (Fig. 87 A). Excretory duct long, cuticular, extending posteriorly along ventral body wall past nerve ring to first half of oesophagus, with prominent nucleus present immediately posterior to base of excretory duct (Fig. 87 A). Males: 13.5 (9.6–16.9) long; maximum width 0.40 (0.24–0.59). Nerve ring 0.585 (0.526–0.640) from anterior end. Oesophagus 1.35 (1.10–1.55) long. Tail 0.428 (0.301–0.564) long. Single testis originating posteriorly, extending anteriorly and looping back on itself. Posterior pre-cloacal sucker bordered by radially situated muscle bands, 1.70 (1.25–2.10) from posterior end (Fig. 87 B). Spicules equal or slightly sub-equal, gouge shaped with median serrated margins; left spicule 1.12 (0.90–1.30) long, right one 1.14 (0.87–1.35) long. Gubernaculum with Y-shaped sclerotized body, 0.139 (0.101–0.172) long. Eleven pairs of sessile caudal papillae: four pairs pre-cloacal, one pair ad-cloacal, and six pairs post-cloacal, of which one pair are phasmids. Median papilla immediately anterior to anterior margin of cloacal opening (Fig. 87 B). Females: 15.1 (9.9–18.6) long; maximum width 0.43 (0.33–0.53). Nerve ring 0.613 (0.564–0.677) from anterior end. Oesophagus 1.42 (1.15–1.60) long. Tail 0.380 (0.245–0.498) long. Ovaries coiled. Anterior ovary at level of, or posterior to, oesophago-intestinal junction, in anterior third of body. Posterior ovary in posterior fifth of body (Fig. 87 C). Oviducts extending beyond vulvar region, reflexing and giving rise to thin-walled uteri containing eggs. Vulval opening a transverse slit. Eggs ovoid, thin-shelled, 0.067 x 0.041–0.079 x 0.049.

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.
