EMU-842 Scleroplax granulata Rathbun, 1898 UABC, USNM17497 Scleroplax sp. UABC Material examined (UABC), new range and host: 10 males, 10 females, Punta Banda estuary, Ensenada, Baja California, 16 May 2006; in burrows of Neotrypea californiansi s and N. gigas (new host record) and 1 male, 1 female, same locality and date; in burrows of U. macginiteorum Williams, 1986 (new host record); 55 males, 54 females (24 ovigerous), 15–17 July 1999 and 6 males, 18 females (8 ovigerous), 16 September 1999, El Coyote estuary, Punta Abreojos, Baja California Sur, México; in burrows of N. californiansi s and N. gigas. Remarks. The present records extend the distribution of S. granulata about 1000 km southward, from Ensenada, Baja California to El Coyote estuary, Punta Abreojos, Baja California Sur, México and N. gigas as a new host. Hendrickx (1984, 1995), with some hesitation, recorded S. granulata as occurring in Estero El Verde, Sinaloa, México. The identification of the female specimen (EMU-842) on which Hendrickx based his report shows that it is instead an undescribed species of Pinnixa. The tip of the maxilliped dactylus of the new species clearly overreaches the tip of the propodus (Fig. 1 D), the flat carapace is transversally subrectangular and the WL3 is much longer than the other legs. Scleroplax granulata is a common commensal in the middle and low intertidal mud burrows of the echiurid Urechis caupo and the mud shimps N. californiensis, N. gigas and U. pugettensis (Garth & Abbott, 1980; present paper). Ricketts et al. (1985) recorded S. granulata in burrows of Upogebia sp., at Punta Banda estuary, Ensenada, Baja California, México. In this locality S. granulata has been collected in burrows of the only species of Upogebia, U. macginiteorum (see, Campos & Campos, 1989). Other crab species that live in burrows of the same hosts include Pinnixa franciscana Rathbun, 1918, and P. schmitti Rathbun, 1918 (Zmarzly 1992).

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.
