Abstract: Abstract: This paper reports a newly recorded monogenean in China, Salsuginus bermudae Rand Wiles, 1987, found on the gills of an exotic fish, Gambusia affinis Baird and Girard, from Guangzhou, Guangdong Province. The shape of our specimens basically agrees with the original description except for the dimensions of the whole worms, the shape of the connective bars and the number of the marginal hooks. The specimens are deposited in the Lab of Fish Parasitology, College of Life Sciences, South China Normal University.
