Epipenaeon latifrons (Isopoda: Bopyridae) and Pandarus rhincodonicus (Copepoda: Pandaridae), New Records of Parasitic Crustacea for the Philippines
Bibliographic record
Abstract
Two species of parasitic crustacean namely Epipenaeon latifrons Bourdon, 1979 (Isopoda: Bopyridae) and Pandarus rhincodonicus Norman, Newbound and Knott, 2000 (Copepoda: Pandaridae) were identified from recent collections. The former species was recovered from the branchial chambers of the Indian white prawn, Fenneropenaeus indicus (Decapoda: Penaeidae) caught from the waters off Matnog port, Sorsogon and Lucena, Quezon. The latter species was found on the edges of the fins and lips, and gills of the whale shark, Rhincodon typus (Orectoloboformes: Rhincodontidae) on necropsy stranded off the coast off Jagna, Bohol, Philippines. Prawns infected with E. latifrons exhibited characteristic bulge of the carapace on the side of the infected gill chamber. Specimens were preserved and kept in 80% ethyl alcohol. Whole and dissected parts of specimens were studied by clearing in lacto-phenol and mounted temporarily or gradually dehydrated in increasing grades of ethyl alcohol, some stained, and mounted in Canada balsam on glass slides for microscopic examination. Based on the Philippine materials, the two species are described and measurements of both males and females are given; drawings and photographs of them are also provided. Epipenaeon latifrons and Pandarus rhincodonicus are reported for the first time in the Philippines, constituting new locality records. Key words: Epipenaeon latifrons , Copepoda, Isopoda, Pandarus rhincodonicus , Philippines

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.
