Abstract

Currently, Leodice has 34 species recorded worldwide. Among these, seven species are known along the Brazilian coast. This study is based on material collected during the Marine Algae project conducted in 1981 along the Continental Shelf of the State of Paraíba, at depths of 10-35 m. In this study, we present three new records: L. pellucida comb. nov. for South America, L. marcusi for northeastern Brazil, and L. unifrons for the State of Paraiba. A new species of Leodice is described from the State of Paraiba, Northeast Brazil, Leodice ivanildae sp. nov. This taxonomic study increases the number of known species of Leodice to 37, with nine occurring in Brazil. Additionally, it expands the species of Leodice known from the State of Paraiba, Brazil, from two to six.

Stored with the screening record, where it is evidence for the labels above.

Teacher imitation

Not 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.
