Abstract
Ericiolus bendifii Archontikis, J.G. Millán, A. Winter & Jer. R. Young sp. nov. Figs 8–15 SYNONYMY: Ericiolus? sp. sensu Young et al. (2003, p. 85, pl. 39, fig. 14). DESCRIPTION: Coccosphere shape unknown, possibly subspherical or saddle-shaped but found collapsed. It consists of c. 50–70 triradiate, star-shaped nannoliths probably forming a single-layered cover. Nannoliths with three coplanar bifurcate rays. The rays are symmetrically arranged (120° angle between them) and bifurcate near the centre of the nannolith with the bifurcations directed radially. The bifurcations are parallel-sided, and tips of each bifurcation are directed distally. On the distal side of the nannolith, there is an elongate central spine with a robust terminal knob. On the proximal side of the nannolith, axial grooves run along the rays from the bifurcations to the centre where they meet to form a small central pore (Fig. 12). DIMENSIONS: Coccosphere diameter 2.5–4.5 μ m; nannoliths 0.3–0.6 μ m long and wide. Ray 0.1–0.3 μ m long. HOLOTYPE: Stub no. 302/2 deposited at the facilities of NHM, UK (PM NF 4663 193–64). Specimen shown in Fig. 8. PARATYPE: Stub no. 459/2 deposited at NHM, UK (PM NF 4814 275–53). Specimen shown in Fig. 9. TYPE LOCALITY: North-western Mediterranean and Alboran Seas (37° 25.8 ʹ N, 0°25.3 ʹ W, depth 42.5 m (DCM), October 1999, MATER-II Cruise, Station 69–11). DISTRIBUTION: Subtropical low-photic waters. NUMBER OF SPECIMENS STUDIED: 16. ETYMOLOGY: After Professor El Mahdi Bendif (Institut des Sciences de la Mer de Rimouski), in recognition of his contributions to the field of extant coccolithophore genetics. REMARKS: Young et al. (2003) previously reported the holotype when examining plankton assemblages of Mediterranean waters and identified via SEM the possession of bifurcate rays in its nannoliths. The authors argued that this specimen (their p. 85, pl. 39, fig. 14, labelled as ‘ Ericiolus? sp.’) was reminiscent of Ericiolus, and although its morphology was incompatible with the generic description, the form probably represented a closely related taxon. This is now confirmed via our morphologic and biometric findings and therefore, it is established as a discrete morphospecies. The species differs in possessing nannoliths with three bifurcated rays, vertically directed ray-tips and an elongate central spine with a terminal knob. The bifurcation occurs near the nannolith centre.

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.
