“…These metacercariae were identified as Mesostephanus Lutz, 1935 due to the presence of a spherical oral sucker, a ventral sucker slightly pre-equatorial and smaller than the oral sucker, the voluminous tribocytic organ and the genital primordial excretory vesicle I-shaped. Four species of Mesostephanus have been described for the region: M. haliasturis Tubangui et Masilungan, 1941 for Haliastur indus intermedius Blyth, 1865 from the Philippines (Tubangui & Masilungan, 1941); M. neophocae Dubois et Angel, 1976 for Neophoca cinerea (Péron, 1816) and Mirounga leonina (Linnaeus, 1758) from Australia (Dubois & Angel, 1976); M. haliasturis and M. scottae Cribb, Barker et Beuret, 1995 for Phalacrocorax sulcirostris (Brandt, 1837) and P. varius (Gmelin, 1789), and M. pelecani Cribb, Barker et Beuret, 1995 for Pelecanus conspicillatus Temminck, 1824 from Queensland, Australia (Cribb et al , 1995).…”
