Abstract
Proscoloplos cygnochaetus Day, 1954 Figure 25 Proscoloplos cygnochaetus Day, 1954: 21, fig. 3a–f; 1967: 538, fig. 23.1e–g; Meyer et al. 2008: 879–889, fig. 1; Blake 2017: 118–120, fig. 58a–f. Proscoloplos confusus: Hartmann-Schröder 1962: 133–134, figs. 161–164. Proscoloplos bondi: Kelaher & Rouse 2003: 909–917, fig. 2. Material examined. Western Australia: King George Sound, Vancouver Peninsula, near Mistaken Island, 35°04’S, 117°56’E, 13.12.1983, intertidal, coll. H.E. Stoddart, AM W.23614, 6 specimens. New South Wales: Ben Buckler rocks at north end of Bondi Beach, coralline algal turf, 29.05.2000, coll. G. Rouse, 33°53’42”S, 151°16’48”E, AM W.29015, paratypes of P. bondi, 7 specimens. Type locality. Tristan da Cunha. Description. Body width 150–300 µm, length 2–3 mm, 22–38 chaetigers (Fig. 25A, C). Prostomium round, without eyes, two peristomial segments (Fig. 25 A–D). Transition from thorax to abdomen indistinct. Branchiae from chaetiger 6–8, oval, same length as notopodia or slightly longer (Fig. 25A, B). Notopodial postchaetal lobes digitiform, increasing towards posterior (Fig. 25A, D). Neuropodial lobes short, papilliform, almost disappearing in abdomen (Fig. 25A). Notochaetae crenulated capillaries in all segments; neurochaetae crenulated capillaries in all segments, besides swan-shaped chaetae in abdominal segments (starting from chaetiger 6–9) (Fig. 25B, E). Pygidium with four short cirri (Fig. 25A, C). Distribution (bases on literature). Chile, Argentina, South Africa, Atlantic French coast, Australia, Western Australia, New South Wales. Habitat. Intertidal and upper subtidal, sand, algae. Remarks. Proscoloplos cygnochaetus was described from the South Atlantic Ocean, Tristan da Cunha Island (Day, 1954). Since, this species has been redescribed by Kelaher & Rouse (2003) (as P. bondi), Meyer et al. (2008), and Blake (2017). Meyer et al. (2007) investigated both morphological and molecular data on three Proscoloplos species and concluded that Proscoloplos confusus Hartmann-Schröder, 1962 and Proscoloplos bondi Kelaher & Rouse, 2003 are junior synonyms of P. cygnochaetus. This was accepted by Blake (2017). The specimens studied here are in agreement with previous descriptions. The present study expands the distribution of P. cygnochaetus to Western Australia.

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.
