First record of Sergestes belonging to edwardsii species group (Sergestidae, Crustacea) from the Indian Ocean
Bibliographic record
Abstract
Sergestes edwardsii Kröyer, 1855 species group is composed of 9 species: S. semissis (Burkenroad, 1940); S. gibbilobatus (Judkins, 1978); S. orientalis (Hansen, 1919); S. geminus (Judkins, 1978); S. tantillus (Burkenroad, 1940); S. consobrinus (Milne, 1968) California Current Form; S. consobrinus (Milne, 1968) Central Form; S. edwardsii (Kröyer, 1855); S. brevispinatus (Judkins,1978). The bathypelagic shrimps belonging to the genus Sergestes are being studied from the IIOE material for its taxonomy and distribution. Two species, S. brevispinatus (Judkins,1978) and S. edwardsii (Kröyer, 1855), have been collected by the research vessels ANTON BRUNN, ARGO, DIAMANTINA, METEOR, OSHORO MARU and VARUNA in the Indian Ocean for the first time. Sergestes edwardsii is broadly distributed throughout the tropical Atlantic; it occurs from the New Land Plaza, Canada, to the wide of the Great Power of the North; throughout the Caribbean and Gulf of Mexico. Records at high northern latitudes in the Western Atlantic are probably due to transport by the Gulf Stream (Judkins, 1978). In Brazil it occurs in Para, in the Archipelago of Are Peter and Sao Paulo, Great River of North Fermando De Noronho (D’Incao, F., 1995, 1998). Specimens of the present material are housed in the Marine Reference Collection and Resource Centre (MRC&RC), University of Karachi.

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.
