Abstract
Lycodes diapterus, the type species of Furcimanus, has been divided into as many as three subspecies (L. diapterus diapterus, L. d. beringi, and L. d. nakamurae). Although L. d. nakamurae has been broadly recognized as a distinct species by recent authors, the status of L. d. beringi is unresolved, and several authors have noted the need for a comprehensive morphological study of L. diapterus. Based on an examination of nearly 500 specimens collected from Kamchatka to California, we herein recognize Lycodes beringi as a valid species distinguished from L. diapterus by meristics and squamation. Lycodes beringi is distributed from southeastern Kamchatka through the Bering Sea, Commander and Aleutian Islands, Gulf of Alaska, and south along the North American west coast to Puget Sound, while L. diapterus ranges from the Pacific coast of Vancouver Island south along the U.S. west coast to southern California. In this report we document the morphological variation present in L. diapterus and L. beringi and designate a lectotype for L. beringi. We also provide diagnoses, descriptions, and distribution information for both forms, and compare them with closely related congeners, providing comments on the subgenus Furcimanus.

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 it
