Redescription of Phagicola pithecophagicola Faust, 1920 (Digenea: Heterophyidae), the type species of Phagicola Faust, 1920.

Phagicola pithecophagicola Faust, 1920, the type species of Phagicola Faust, 1920 (Trematoda: Heterophyidae: Phagicolinae), is redescribed on the basis of examination of type specimens (syntypes) from the monkey-eating eagle, Pithecophaga jeffreyi, from the Philippines. The oral sucker is armed with 1 complete row of 16 circumoral spines (10-19.5 microns long by 4-8 microns wide) and 4 accessory spines (5.5-8 microns long by 3-4 microns wide) on the dorsal side; this arrangement differs from the original description and later redescriptions, where only 12 circumoral spines in 1 row were reported. The ventrogenital sac contains a ventral sucker and a large gonotyl with 2 small, often indistinct, lobes containing a few refractile bodies. The intestinal ceca extend reaching down to the ovarian level. The uterus is confined to the acetabulo-ovarian region, and eggs are 17-20 microns long by 9-10 microns wide.
