Fig. 2.

The new second intermediate host, Lateolabrax japonicus (A) (bar = 30 mm), a metacercaria (B) (bar = 0.05 mm), and an adult (C) (bar = 0.25 mm) of Metagonimus takahashii. Metacercariae were characterized by a disc shape, ventral sucker displaced from the median, yellow-brownish pigments scattered in the body, and excretory bladder (EB) flat and V-shaped. Adults were recovered from a cat experimentally infected with the metacercariae, and characterized by a small-sized, rightwardly displaced ventral sucker (larger than the oral sucker), the uterine loop passed between 2 testes (T) and vitellaria (arrows) distributed over the posterior end of the right testis.
