【Abstract】 This paper deals with a new monogenetic parasite Silurediscoides parasoti sp.nov. from the gill filament of Silurus meridionalis Chen from Chongqing in the summer of 1991. The measurements are in millimeters and the type specimens are deposited in the Biology Department of Chongqing Normal College. Silurodiscoides parasoti sp. nov. is much closely similar to Silurodiscoides asoti Yamaguti (1937) in shape of opisthohaptor, but it differs from the latter in that it has different shape of dorsal anchors, dorsal connective bar,copulatory tube and supporting apparatus.更多还原
