In the examination of marine fishes for digenitic trematodes in coastal areasof Xiamen,South Fujian, China.One new monorchid and one new bivesiculid tremaotde werecollected.The type specimens are diposited in the Dept.of Biology,Shantou University. Theirdiagnoses are as follows:1.Monorchlis Xiamenensis sp.nov.Fig.1Fifty speocirnens of th is species were colleced in the intestine of Glossogobius olivaceus.Bodyoval,0.768～1. 232 mm long hy 0. 400～0; 600 mm broad,covered all over with minute spines.Oral sucher rounded, subterminal,0. 082～0. 126 × 0.1 00～0.1 32 mm.
