Abstract
Rhabdochona rotundicaudatum Byrne, 1992 Description (after Byrne 1992a). With characteristics of the genus. General characteristics: see those for R. cascadilla above. Male paratypes (means with ranges in parentheses): body 5.8 (5.0–6.7), prostom 0.018 (0.017–0.023), vestibule 0.090 (0.081–0.100), muscular oesophagus 0.224 (0.188–0.251) and glandular oesophagus 1.6 (1.2–1.9) long. Small bifurcate deirids 0.051 (0.033–0.057), nerve ring 0.133 (0.127–0.137) and excretory pore 0.200 (0.195–0.208) from anterior end. Caudal papillae digitiform: 18 to 21 pre-cloacal and 11 to 13 post-cloacal, mostly subventral. Phasmids minute, located just distal to most posterior pair of caudal papillae. Left spicule 0.388 (0.342– 0.421), its alate portion (blade) 0.183 (0.0.159–0.196) long. Right spicule 0.092 (0.087–0.101) long, relatively stout, with dorsal projecting barb at distal end and a bulbous, convex proximal end (Fig. 50 B). Length ratio of right to left spicule 1:3.93 to 1:4.22. Tail 0.306 (0.266–0.365) long, tapering and ending in a rounded tip (Fig. 50 A). Female paratypes (means with ranges in parentheses): body 10.6 (8.9–13.4), prostom 0.026 (0.023–0.028), vestibule 0.107 (0.097–0.120), muscular oesophagus 0.278 (0.261–0.290) and glandular oesophagus 2.27 (2.08– 2.54) long. Deirids 0.066 (0.060–0.076), nerve ring 0.158 (0.146–0.179) and excretory pore 0.233 (0.212–0.265) from anterior end. Vulva located near midpoint of body, 6.0 (4.9–7.3) from anterior end. Phasmids minute, posterior to midpoint of tail. Eggs ovoid, smooth, without filaments or floats, 0.023 (0.023–0.024) x 0.038 (0.036– 0.039). Tail 0.215 (0.188–0.241) long, tapering and ending in a rounded tip (Fig. 50 C). Note: Byrne (op. cit.) also provided measurements for the male holotype and female allotype of R. rotundicaudatum.

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.
