Genital synus presented. Ventral and genital suckers usually not combined. Cirrus and bursa absent. Two testes located in posterior part of the body. Vitellaria in posterior part of the body."

Metagonimus Yokogawai
''Metagonimus yokogawai'' is a species of a Trematoda, trematode, or fluke worm, in the family Heterophyidae. It is a human parasite causing metagonimiasis. It is among a few species of ''Metagonimus'' that cause metagonimiasis diseases (others being ''Metagonimus takahashii, M. takahashii'' and ''Metagonimus miyatai, M. miyatai''). Distribution This species occurs in Korea, China, Taiwan, Japan, Russia, Indonesia, Israel, and Spain. This species is found in areas with sweetfish, and that includes western and eastern riversides. It is basically found in places with water. Description ''Metagonimus yokogawai'' has adult flukes that parasitize the small intestine and causes inflammation. This species was discovered by Fujiro Katsurada with egg samples from Japan and Taiwan With this discovery, he was able to make a new genus of trematodes that this new parasite would fall under The size of these eggs are about 29 μm. Evidence also suggest that this parasite was present dur ...

Galactosomum Bearupi
''Galactosomum'' is a genus of flukes in the family Heterophyidae. There are currently 28 recognised species within the genus. They mainly infect aquatic birds, but often infest fish as larvae. Three species are known to use marine mammals as hosts. Description The excised spherical metacercaria is 2.7–4.9 mm long. Generally, only one is found per fish. Life cycle Some species of ''Galactosomum'' cause infected fish to swim closer to the surface and colorfully flash their underbellies. In fish, symptoms can be similar to those of whirling disease caused by the unrelated parasite ''Myxobolus cerebralis''. Gastropods hosting select species suffer from sensory impairment due to infestation. This makes these prey animals more likely to be consumed by aquatic birds, providing a host for the parasite to reach the mature stage of its life cycle. ''Galactosomum'' cannot survive in human hosts. Species *'' Galactosomum baylisi'' (Gohar, 1930) *''Galactosomum bearupi'' Pearson, 197 ...

Centrocestus Formosanus
''Centrocestus formosanus'' is a trematode parasite of Asian origin that has found its way into North American streams and rivers. It not only affects the fountain darter but many species of commercially important fishes. It is also capable of infecting humans The parasite is transmitted via a freshwater snail Red-rimmed melania ''Melanoides tuberculata'' Vergara D. & Velásquez L. E. (2009).
