Abstract
Lesueurigobius stironensis sp. nov. urn:lsid:zoobank.org:act: CCEB6FA7-DA02-47B3-8A38-D7CA369E9E79 Fig. 11 F–I Diagnosis This species is characterised by high, pentagonal otoliths. The shape of the dorsal rim is very characteristic in bearing 4–6 large lobes, with the highest one located at the middle and lowering towards both ends. The other rims are nearly straight and perpendicular to each other. The sulcus is deep and ventrally directed at the anterior. Etymology The species is named after its type locality, the Torrente Stirone. Type material examined Holotype ITALY: a left otolith (IRSNB P 9689, Fig. 11F). Paratypes ITALY: 21 specimens of which 3 are figured (IRSNB P 9690– P 9692, Fig. 11 G–I). Type locality and horizon ITALY: Tortonian Clay exposed in the Torrente Stirone. Dimensions of the holotype Length = 1.75 mm, height = 1.80 mm, thickness = 0.55 mm. Description The otoliths are tall and pentagonal. The dorsal rim bears 4–6 large lobes; the largest and highest lobe and highest lobe is located in the middle and marks the highest point of the otolith. The anterior and posterior rims are almost straight, and the ventral rim is straight in the holotype but very slightly curved in some of the paratypes (e.g., Fig. 11I). In some specimens, however, the anterior rim is crenulated at the lower part and a small concavity is observed in the middle part of the posterior rim (e.g., Fig. 11G). The inner face is more or less flat; the outer face is convex. The sulcus is deep, clearly delimited, and well-divided into ostium and cauda; the anterior part of the ostium is directed ventrally. The cristae are well-developed. The ostium is large and expanded ventrally, with a concavity at the antero-dorsal margin. The cauda is rod-like and rounded at the posterior end. There is a marked swollen collicular crest just below the cauda. Remarks The otoliths of this new species are easily recognised and the shape of the dorsal rim is consistent regardless of size among the available material. The sulcus shape and a slightly asymmetric dorsal rim of the otoliths are the main reasons for attributing this new species to the genus Lesueurigobius. Several Lesueurigobius otoliths have been reported from the Miocene of the Mediterranean (e.g., Reichenbacher & Cappetta 1999: pl. 3, figs 1–5, L. vicinalis (Koken, 1891); Hoedemakers & Batllori 2005: pl. 11, figs 9–13, Lesueurigobius sp.), but none of them present the characteristic morphology of the dorsal rim as our new species.

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.
