Bibliographic record
Abstract
Rhabdias bakeri Tkach, Kuzmin et Pulis, 2006 (Fig. 15) Synonyms: Rhabdias ranae Walton, 1929 in Baker (1979). Host: Lithobates pipiens, L. sylvaticus (Amphibia: Anura: Ranidae). Site: lungs. Distribution: Northern Nearctic (northern U.S.A. and southern Canada). Description (after Tkach et al. 2006). Body 7.090 (4.051 –10.692) mm long, maximum width 245 (139–406) near vulva. Cuticular inflation less prominent in anterior part, from anterior end to level of distal part of oesophagus. In younger specimens, body cuticle evenly inflated along whole body. Oral opening oval, situated between 2 lateral pseudolabia. Each pseudolabium hemispherical in dorso-ventral view, rounded triangular in lateral view, with 2 small submedian protuberances (reduced submedian lips), each bearing a papilla. Vestibulum almost slit-like in apical view. Buccal capsule 17 (15–20) wide, 9 (7–12) deep, funnel-shaped in lateral view, round in apical view, with thick sclerotised walls. Lumen of buccal capsule narrow, cylindrical in lateral view. Anterior edge of buccal capsule slightly behind anterior edge of oesophagus. Oesophagus elongated, comparatively narrow, club-shaped, with dilated anterior muscular portion and egg-shaped posterior bulb. Oesophagus length 539 (465– 590), or 8.0 (5.4–11.9) % of body length. Width of oesophagus anterior end 36 (31–41), width of muscular dilation 43 (36–49), minimum width of glandular part 35 (27–44), width of oesophageal bulb 59 (48–72). Nerve ring encircling oesophagus posterior to its muscular dilation, at 174 (146–211) from oesophagus anterior end (32.3 [27.6–36.9] % of oesophagus length). Excretory pore opening just behind level of nerve ring. Intestine narrow at level of oesophageal-intestinal junction, then widening posteriorly. Rectum narrow, with thick sclerotised walls. Vulva postequatorial. Distance from anterior end to vulva 4.142 (2.297 –6.317) mm, or 58.7 (53.7–63.8) % of body length. Proximal ends of syngonia far overlapping at level of vulva. Egg size 50–61 × 94–113 (n = 19). Tail conical, elongated. Tail length 254 (193–336), or 3.7 (2.7–6.7) % of body length. Inflated body cuticle covering tail up to its tip in younger specimens; in older ones tail tip lacking inflated cuticle. Phasmids situated somewhat posterior to mid-length of tail. Remarks. The species is presumably a specific parasite of L. sylvaticus occasionally parasitizing other frogs (Tkach et al. 2006). Material studied: 33 specimens, including the type series (17 specimens, USNPC). References: Baker (1978), Tkach et al. (2006).

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.
