A new species of Valettiopsis Holmes, 1908 (Crustacea: Gammaridea: Lysianassoidea) from abyssal waters off California
Bibliographic record
Abstract
Deep-sea sampling off the central California coast has provided numerous material of a new amphipod species of the genus Valettiopsis Holmes, 1908. Valettiopsis concava sp. nov. is described from abyssal collections taken from baited traps and sponge stalk communities. Morphological characteristics which distinguish the new species from its congeners are found in the dorsal profile of the body, integument surface, and shape of coxa 2 and basis of pereopod 7. This contribution presents the second recorded species of the genus Valettiopsis described from the north Pacific, the first being the type species V. dentata Holmes, 1908. The new species is fully illustrated and compared with related species. The generic identity of Valettiopsis ruffoi Serejo & Wakabara, 2003 is discussed. A key to Valettiopsis species is provided.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
