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
