Bibliographic record
Abstract
Parapagurus pilosimanus Smith, 1879 (Fig. 21) Parapagurus pilosimanus Smith, 1879: 51. Parapagurus pilosimanus. — Lemaitre, 1986: 529, figs. 1C, D, 3A–E, 4C, D, 5E, F, 6I, J, 7C, G, 8H, 9F–H.— Lemaitre, 1990: 13, figs. 3, 4, 5A, 6, 39A, B (lit.).— Jones & Brewer, 2012: 105 (Mauritania, 1400–1500 m).— Cardoso & Lemaitre, 2012: 597, fig. 4 (South Atlantic, 997 m). Parapagurus pilosimanus: García Raso, 1996: 739 (In part). Material examined. MU08, 1308 m, (4); MU09, 1412 m, (2). Males: 6.34–12.65 mm, females: 7.44–9.10 mm Habitat. Reported on mud, mud with stones, muddy sand, sand, broken shells, corals and pumice bottoms, inhabiting gastropod shells of genera Fussus, Natica and Trophon and also a scaphopod shell of Dentalium (see A. Milne-Edwards & Bouvier 1900). A. Milne-Edwards & Bouvier (1900) reported the association with Epizoanthus and actinians, and Urzelai et al. (1990) with Epizoanthus paguriphilus Verrill, 1883. Williams & McDermott (2004) reported the platyhelminthe Ectocotyla hirudo (Levinsen, 1879) living in the shell and the bryozoan Arachnoidella dhondti (Franzén & Sandberg, 2001) over the pereiopods of the hermit crab. Our material was captured on sandy mud, muddy sand and sandy bottoms, always in carcinoecia of Epizoanthus paguriphilus. Distribution. Eastern Atlantic, from southwest of Iceland and Faeroe Islands to the Gulf of Guinea, and in Tristan da Cunha Island; western Atlantic, from off Nova Scotia (Canada) to Guyana (Lemaitre 1989, 1990). The species was also reported from Walvis Ridge (Cardoso & Lemaitre 2012). The recorded depth range is between 102 and 3864 m, but the species is mainly reported from 400 to 1400 m (Lemaitre 1989). Our specimens were mostly captured between 1100 and 1600 m. In the same area, recent remote operated vehicle (ROV) observations located P. pilosimanus and its symbiont zoanthid Epizoanthus paguriphilus at 1400–1500 m depth (Jones & Brewer 2012). Remarks. Our specimens concur with the descriptions and figures given by Lemaitre (1986, 1989) and can be distinguished from other allied species in the area by its unarmed mesial and lateral faces of meri, carpi and propodi of the ambulatory pereiopods; the symmetrical posterior lobes of the telson; and the presence of 2 or 3 irregular rows of conical scales on the propodal rasp of the fourth pereiopods.

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.
