Flukes of the Family Microscaphidiidae Looss, 1900 (Trematoda: Digenea) from the Green Sea Turtle, Chelonia mydas L. (Reptilia: Chelonia) in the Philippines with Description of Three New Species
Bibliographic record
Abstract
A total of 15 green sea turtles, Chelonia mydas L. were examined at various times for parasites from the coastal areas of Bohol and Zamboanga, Philippines. Among others, trematodes belonging to the family Microscaphidiidae Looss, 1900 were recovered following the concentration sedimentation decantation technique. Specimens were stained in borax carmine, cleared in oil of cloves and mounted in Canada balsam for microscopic examination. Twelve species including 3 new species of trematodes representing 6 genera of the family Microscaphidiidae Looss, 1900 were identified. These are: Microscaphidium reticulare (van Beneden, 1854) Looss, 1901; Microscaphidium aberans Looss, 1902, Microscaphidium warui Blair, 1986; Deuterobaris proteus (Brandes, 1891) Looss, 1900; Angiodictyum parallelum (Looss, 1901) Looss, 1902; Angiodictyum glossoides Blair, 1986; Angiodictyum longum Blair, 1986; Angiodictyum undulatum n. sp.; Angiodictyum dejesusi n. sp.; Polyangium manueli n. sp.; Octagium sagitta (Looss, 1899) Looss, 1902 and Polygorgyra choladus Blair, 1986. Angiodictyum undulatum, A. dejesusi and Polyangium manueli were described and illustrated as new species. A. undulatum differs from all species of the genus by its lateral margin thrown into folds giving an undulating appearance of the worm, vitellaria present only in the median area and their absence in lateral fields. A. dejesusi is differentiated from the closely related species, A. longum by its vitellaria extending anteriorly to level of anterior testis and not beyond it, the pharyngeal position of the genital pore and the relatively short esophagus. P. manueli differs from P. linguatulum, the only valid species of the genus, by its ovoid shape, the limited extent of vitellaria which is behind the testes and the more anterior location of the genital pore just behind the pharynx. This is the first report of these trematodes in the Philippines constituting a new locality record for these species. Keys to separate the genera of the family Microscaphidiidae and species of the genera Microscaphidium and Angiodictyum occurring in marine turtles in the Philippines are provided. Keywords: Angiodictyum dejesusi, Angiodictyum undulatum, Chelonia mydas, Microscaphidiidae, Philippines, Polyangium manueli

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.
